Dear hydraulics practitioner,
Consider for a moment, one machine owner's real-life tragedy:
"I have a problem with my excavator. Here's an overview of events so far:
1. The hydraulic pump was lugging down the engine when attempting to operate most of the hydraulic functions.
2. We had a team of hydraulics guys out who said it is a problem with the engine.
3. A diesel mechanic came out and said it is a hydraulics problem.
4. We had another guy come out and he said the pump needs to be taken off. Only to hear from him that he is unable to repair the existing pump and will quote us for a new one.
5. We then took the existing pump, in pieces, to another guy who said he can repair the pump at a reasonable cost. We gave him the go ahead. The same guy bench tested the pump in my presence up to 400 bar.
6. We then reinstalled the pump on the machine and are now not getting any functions! We were then told that it could be a valve bank problem.
7. We have stripped the two valve banks about 8 times on instructions from quite a few other 'experts' but to no avail.
We have now come to the end of our tether and are at our wits end because we haven't the faintest clue what to try next."
This situation is a complete disaster. The original problem hasn't been properly identified, the pump is in 100 pieces, and when it's finally reinstalled on the machine there's a different problem.
Machine parked. Bills piling up. And no solution in sight. You can't help feeling sorry for the besieged machine owner. But as you can see, this machine owner had no shortage of help. The problem was none of this help knew what they were doing.
It's obvious that no one who was asked had the ability to drill down and really understand this machine's hydraulic system BEFORE offering an opinion.
And their ego prevents them from telling the machine owner:
"I don't know what's causing this problem. Because I don't understand this machine's hydraulic system."
So they grope and guess instead. And lose all credibility in the process. (If you're curious to know what was causing this problem, stay tuned because I will reveal what it was later).
But in fairness to everyone involved, the reality is today's mobile hydraulic machines have some of the most complex hydraulic systems you'll come across.
This is particularly true when it comes to many of the controls devised for variable displacement pumps and motors. Semi cross-sensing, power summation, open and closed center load sensing, positive and negative displacement control, constant torque and constant speed control for closed circuits, just to name a few.
Even a directional control valve is not just a directional control valve on a mobile machine. It can incorporate power beyond, anti-saturation, work port pressure limitation, load signal amplification, pre and post compensation, anti-cavitation, differential pressure limitation and much more.
This helps explain why the hopeless situation the above machine owner finds himself in happens a lot. And it also explains why dedicated, hands-on, at-the-coal-face practitioners working on mobile hydraulic equipment regularly tell me they need a manual just to decode the machine manual. They do.
So for some time now, I've been paying attention to what guys like you who work on mobile hydraulic machines need to understand to succeed. And it's my observation that nobody is explaining it very well, if at all. I'm not talking about the basics. I'm talking about advanced mobile hydraulics. And the good news is, it's NOT difficult to master, because...
If you grasp just a few core principles, you can use them to chunk down and understand any mobile hydraulic system. Regardless of its complexity. Let me give you a couple of quick examples. Look at this hydraulic symbol:
It looks a bit like a relief valve doesn't it? And it is a close relative. But it's actually a relieving hydrostat. It also has a cousin, the reducing hydrostat. In mobile hydraulic systems, hydrostats are common and are used for a lot of different control functions. These include differential pressure limitation, load signal amplification, pre and post compensation and anti-saturation, just to name a few.
What this means is, when you understand a hydrostat's principle of operation (they're really quite simple) none of the many functions they're used for will be a mystery to you. Plus, you'll instantly recognize them on a drawing and quickly identify the function they're carrying out.
Now look at this simple circuit:
There's nothing about this circuit you won't instantly recognize. Except perhaps the mechanical link (1) between the cylinder's piston rod and the directional control valve's sleeve (2). What this simple circuit represents is called a follow-up servo mechanism.
And a follow-up servo mechanism is a feature of most variable pump and motor controls. This means once you grasp the operating principle of a follow-up servo mechanism, and are able to recognize its various forms, there isn't a pump or motor control in creation you won't immediately understand.
The above examples are just two of a handful of principles, which when understood, empower you to decode and understand the most complex of hydraulic systems. What to others appears to be some sort of exotic dialect out of a Star Wars movie, you'll be able to translate effortlessly on demand. And if you step up and enrol in my brand NEW mobile hydraulics training, I'll teach all of these principles to you, and much more.
So if you make your living, or a significant part of it, off the back of mobile hydraulic equipment, or you plan on doing so, keep reading, because this training is designed especially for you. It's called The Definitive Guide to Mobile Hydraulics. And it's one you shouldn't skip.
Before I tell you all about The Definitive Guide to Mobile Hydraulics, let me tell you what it's NOT: It's NOT a text book. And it's NOT a correspondence course. It's a learning SYSTEM that combines printed materials, computer simulation and screen-capture videos.
AND it's chock full of practical, mobile hydraulics know-how you can absorb at your own pace, at your convenience, and in the comfort of your own home, office or workshop.
The training is divided into 14 modules. Each module begins with a review of the fundamentals, and from there moves quickly into the advanced aspects of mobile hydraulic control. Explanation of the more advanced concepts is enhanced by 54 simulation videos with a total running time of 672 minutes (11.25 hours!).
Being an advanced mobile hydraulics practitioner means you've got to be comfortable reading drawings. There's no two ways about it. Which is why the first module deals with schematics and how to read them. And I reveal a simple but powerful technique you can use to decode any hydraulic circuit, regardless of how complex it may appear at first.
Plus, I explain how to interpret symbols with mechanical links, like the follow-up servo mechanism shown earlier. This is important because it empowers you to decode and understand any variable pump or motor control you'll ever come across.
From there we move through a recap of the physical laws of hydraulics. Hydraulics theory, like Pascal's Law for example, is the realm of the basic hydraulics text book. So it's NOT covered here. What is covered instead are the key laws of hydraulics that relate to the mobile hydraulic control systems explained in the subsequent modules.
And while proportional and electronic control are covered in detail, a BIG chunk of this training is devoted to variable pump and motor controls, hydrostatic transmission controls and load-sensing systems. Why? Because for the accomplished mobile hydraulics specialist, this is where the 'money' is. And it's where the money was on the hydraulic excavator described above.
So with this in mind, here's a partial list of the controls explained in each of these four, very important modules:
Variable pump control
Load sensing systems
Variable motor control
Hydrostatic transmissions
As I've mentioned already, each of the 14 modules in this specialized training begins with a review of the fundamentals and moves quickly into advanced territory. Not only are most of the above controls advanced in nature, you won't find them explained in detail anywhere else. And I'm sure of it. Because every mobile hydraulics control expert I know, myself included, had to figure them out for themselves, the hard way. But now you don't.
That said, The Definitive Guide to Mobile Hydraulics is not ONLY about variable pump, motor, load sensing and hydrostatic transmission controls. Here's a taste of what else is in store:

This training literally contains A STACK of mobile hydraulics know-how. It comes with 358 pages of printed materials and 54 simulation videos with a total running time of 11.25 hours! So it's just not possible to list all the knowledge you'll gain here. But at least now you have a good idea.
"I love your information. It's helped me a whole bunch on the mill's Wagner and our Cat 980H. I don't tell them my 'secrets' and I've become THE Go-To-Guy. The operators even wait 7 days for when I come on shift to tell me if there's something wrong with the equipment. I work 6 on, 8 off, and get double time for overtime. Thanks to you."
Jason Laprairie
Grand Forks, Canada
It's taken me 27 years to put all the pieces of this puzzle together on my own. If you've got quarter of a century to spare, you could probably do the same. But I don't recommend it. Not when The Definitive Guide to Mobile Hydraulics lays it all out in front of you in an easy to understand format.
I only wish this training was available to me when I started out. Because it would certainly have propelled me up the 'food-chain'. And here's a quick story to illustrate what I mean. Rick Sosnowski is a long-time inhabitant of 'Planet Brendan'. He's also a battle scarred and war weary heavy equipment mechanic (now retired). He sent me this little insight from the 'coal-face' recently:
"A friend of mine bought a Kobelco 300 at auction. When he put it to work, he found the functions difficult to control - all or nothing (lack of proportionality). He fought the thing for months. Mechanic after mechanic looked at it. A few tried to fix it but none succeeded. Finally, a young guy came along. It took him 30 seconds to identify the problem and 10 minutes to fix it."
The thing about this story is, if you make your living working on mobile hydraulic machines:
-- You DON'T want be the guy who scratches his head, shrugs his shoulders and walks away, hoping for an 'easier' job next time.
-- And You DON'T want to be the guy who has a go at fixing the problem but fails miserably. And leaves with that knot-in-your-stomach feeling.
-- You DO want to be the guy who is able to quickly understand the hydraulic system, zero in on the fault, and fix it. Why?
Just in the past few weeks I've heard from two of my students. Both are sleeves-rolled-up, oil-on-hands, mobile hydraulics guys. Zac Grubb is from Ungarie on the east coast of Australia. Ryan Reed is from Kansas City in the Midwest of the United States. Zac works on earthmoving and construction equipment. Ryan is a crane technician. Zac stumbled across me on 23 February, 2014. Ryan arrived on 'Planet Brendan' at 9.33 PM on 21 March, 2010.
Both very quickly became serious students of mine. And both, I'm pleased to report, have recently been rewarded with significant pay rises. Zac secured a raise of $320/week ($8hr). And Ryan, $400/week ($10/hr).
I'll think you'll agree, these are significant raises. Big enough to make a difference. Pay off the credit card. Eliminate mortgage stress. And do something nice to spoil that special someone. A vacation perhaps?
I'm not sharing this with you here as some sort of boast. Just the opposite in fact. The kudos is ALL theirs: Zac's and Ryan's. They learned it. They earned it. The important takeaway from their success is: don't ever UNDERESTIMATE the value of real, authentic hydraulics know-how. And the payback that comes from investing in yourself.
Why would you want to work your way up the ladder s-l-o-w-l-y when you can stand on my shoulders and 'leap-frog' your way to the top?
Anyway, now that you've got a handle on what The Definitive Guide to Mobile Hydraulics is really all about, let me explain exactly what you get:
I'd strongly encourage you to enrol in mobile hydraulics training like this at your local vocational college. But you can't. Such a course does not exist. Not to such an advanced level anyway.
But even if you COULD get this training from a vocational college, it wouldn't come cheap. Just last week I received a brochure from my local chapter of the Fluid Power Society advertising hydraulics courses at a local vocational college. The tuition fees ranged from $875 to $1375.
And that's not the end of it. I've done a lot of part-time study while working full-time. And it can be real stressful trying to attend lectures - or worse still, missing them, when you've got urgent work or family issues to deal with.
The foundation of my training is the program's printed materials (358 pages) organized and presented in study-guide format. Plus, review exercises with answers are included for continuous self-assessment of your understanding.
This means you can progress at your own pace, while studying at a time and place convenient for you. This removes the stress of trying to juggle work and family commitments. Plus, you don't have to endure the time and expense of travelling to and from lectures.
To assist, accelerate and reinforce your learning, you also get 54 videos on USB flash drive. These videos have been prepared and recorded using state-of-the-art computer simulation software and screen-capture video technology. Here's a the first 4 minutes from from one of them, which explains how a differential pressure limiter is used to 'soft start' a hydraulic motor:
Click on the > button, center of screen, to watch the video.
[NOTE: this video clip lost significant quality when it was formatted for the Web.
The actual videos are sharp and clear and can be viewed in 'full-screen' mode.]
The topic of each video has been carefully selected to reinforce and build upon the key concepts presented in each module of the study guide. Furthermore, the videos are fully integrated into the course printed materials. Which means you are prompted when to watch each of the videos as you progress through the training.
The total running time of these videos is 672 minutes (11.25 hours!). And based on what hydraulics training videos with a similar running time sell for, these videos are easily worth $500 on their own.
It's very important to me if you do decide to enrol in this training, that you succeed in becoming a high-paid and in-demand mobile hydraulics specialist. So the last thing I want is for you to get stuck on something you don't understand. And this is why as part of this training you get unlimited question and answer sessions with me. In other words, if you need extra help, you'll get it.
My consulting clients pay me $250 per hour for this type of support. And as you progress through this training, it's not unreasonable to expect you might prevail upon an hour of my time, perhaps more (and that's OK) - making this at least a $250 value.
Becoming a high-paid, mobile hydraulics specialist is not a one-time event; it's an ongoing journey. Which is why I share my best and latest hydraulics intell and advice every month through Hydraulics Pro Club. It comprises a printed newsletter and hydraulics simulation video on CD, delivered by postal air mail each month to anywhere in the world. No hydraulics topic is off limits: design, maintenance, troubleshooting, circuits, controls, componentry and everything else in between. After your free issue, membership is $14.79/month cancellable at any time for any reason. If you're already a member, your existing membership will not be duplicated.
As with all my other training programs, your investment in The Definitive Guide to Mobile Hydraulics includes FREE shipping to anywhere in the world - a $50 value. So the investment is the same no matter where you live.
It's not just the hydraulic control systems on mobile machines that are getting more sophisticated all the time. So too are the electrics and electronics. Which is why every mobile hydraulics specialist should have at least a basic working knowledge of electrical relay and PLC logic circuits.
Sure, it's likely you'll be able to pass off any problems in this area to an electrician. But if you DO have a solid foundation in this, it means you're able to 'talk turkey' with an electrician and work with him more effectively. Relay and PLC Logic For Hydraulic Technicians is a hard copy manual that gives you this foundation. It's a $30 value, and if you're one of the FIRST 16 to invest in The Definitive Guide to Mobile Hydraulics BEFORE it's yours FREE.
If you're one of the FIRST 16 to invest in The Definitive Guide to Mobile Hydraulics BEFORE , I'll roll up my sleeves and work right along side you to help you gain a complete understanding of a mobile hydraulic system of YOUR choice.
This is in addition to the unlimited question and answers sessions on the material contained in The Definitive Guide to Mobile Hydraulics. It means if you have a complex hydraulic machine you have to deal with at work, I'll personally help you become an EXPERT on it.
As my long list of consulting clients know, I bill my time at $250/hour. So this bonus IS a genuine $500 value - that I don't NEED to throw in. Because the unique training presented by The Definitive Guide to Mobile Hydraulics videos and study guide is by itself a sound investment for any serious mobile hydraulics practitioner or mobile equipment user (were I to present this same training in a classroom setting, nobody would gain entry for a penny less than $2000!)
Nevertheless, I am doing this because I'm VERY determined to ensure that anyone who takes immediate, positive action, absolutely succeeds in learning what they need to know. PLUS, there is no 'use-by' date on this support. You can call it in whenever you need to. All at once. Or bit by bit.
HOWEVER, because time is a finite resource for all of us, I obviously can't do this for everyone. So once these 16 coaching/tutorial support slots are filled, this $500 FREE Bonus will be withdrawn - at least temporarily, and quite possibly forever. So if you want to kick your mobile hydraulics expertise up a notch, and become an in-demand and high-paid mobile hydraulics specialist, AND have me personally coach and advise you along the way, then don't fiddle around, secure your place on this training today.
You take NO RISK whatsoever by evaluating The Definitive Guide to Mobile Hydraulics. Because if in the unlikely event you're not absolutely delighted for any reason - or no reason at all, I'll cheerfully refund your entire investment in full. No questions asked. There is no fine print. It's as simple as that.
Even though comprehensive, advanced mobile hydraulics training like this is NOT available from your local vocational college - or anywhere else for that matter, similar training of a hydraulic nature can set you back $1300 (not counting travel expenses and study materials). PLUS you get 54 videos on USB flash drive - worth at least $500. AND unlimited question and answer sessions - a $250 value. Add to this, one month's membership to Hydraulics Pro Club, and FREE shipping - to anywhere in the world - $65 value. PLUS, Relay and PLC Logic For Hydraulic Technicians, AND the one-on-one coaching/tutorial support on a hydraulic system of your choice, together worth $530 for your fast response, and that comes to $2,645.00 total.
You DO NOT have to pay $2,645.00 to become a high-paid and in-demand mobile hydraulics specialist. Nor do you need to spend 27 years trying to figure this out for yourself (like I did!). I must be going soft in my old age, because if you're one of the FIRST 16 to respond before midnight this I'm willing to give all this away to you for only $497 USD.
So basically, I just gave you a $2,148.00 discount on what it would cost you if you COULD get all this mobile hydraulics training and support elsewhere. (And you can't).
OR, if you're a mobile hydraulic equipment owner or user and you wanna slice 'n dice it another way: How much hydraulics assistance can you get elsewhere for $497? On a one-time only basis, not a lot. On an ongoing basis, none at all.
As attractive as this offer is, experience tells me that only about 1 out of every 10 who receive it will respond. Although that's OK with me from a business standpoint, it still bothers me personally.
Because I know how much fitters, mechanics, technicians and mobile hydraulic equipment users will benefit from this training. I read their emails; I talk to them on the phone; I meet them personally at seminars, and hundreds each year tell me that:
"A lack of specialist knowledge is our BIGGEST hydraulics problem."
With this in mind, I hate the thought of someone not getting this training because of some error or omission in my explanation. Which is why I've wracked my brain to come up with possible reasons that might be holding you back.
Here they are:
"I don't know much about hydraulics"
You don't need extensive hydraulics know-how to benefit from The Definitive Guide to Mobile Hydraulics. If you DO have some hydraulics knowledge and/or exposure to mobile hydraulic equipment - great, you'll hit the ground running. But it's certainly NOT an essential requirement because each module begins with a review of the fundamentals, upon which the more advanced concepts are built.
"My computer skills aren't very good"
The very fact that you're reading this tells me you already have the necessary computer skills for this training. You DO need a computer (PC or Mac) to watch the 54 tutorial videos which are an integral part of this training. But this only requires plugging a USB flash drive into your computer.
"Will the videos playback on my Apple Mac?"
Yes.
"Will I get a diploma or certificate when I complete the training?"
Yes. If you complete and turn-in your answers to the review questions at the end of each module, you will be awarded a Certificate of Completion.
"I prefer to work in Metric rather than US units (or vice versa)"
Both US and Metric units are used throughout this training (it's good to be familiar with both). But this isn't a big issue either way since there's virtually no calculations required.
"I'm a long time member of Hydraulics Pro Club. Will I notice duplication of content?"
If you've been a member of Hydraulics Pro Club since it began in March 2009, then some of the subject matter in this training will not be entirely new to you. But this training also contains a lot of material that's never been published in Hydraulics Pro Club. And all of it has been combined in a logical, easy to understand format not available anywhere else. It means if you are a Hydraulics Pro Club member of many years standing, you'll get more out this training more quickly, than a candidate who comes to it without the benefit of such prior learning.
"I already have a stack of books about hydraulics"
The Definitive Guide to Mobile Hydraulics is NOT a book. It's a training program which combines printed materials, computer simulation and screen-capture videos. And besides, there are NO books that explain the advanced mobile control concepts covered by this training. Believe me, I've looked far and wide.
"I live beyond Siberia, so shipping will be too expensive"
Worldwide shipping is included, so the price is the same no matter where in the world you live.
"It looks like a great deal, but I'm not sure I can afford it right now"
"I almost balked at the price, but within a matter of months I had more confidence than I could believe. The knowledge of how to attack any hydraulic problem with your efficient methods had me outshine a number of more experienced diesel mechanics and technicians. This upset some of the older tradesmen. So I now keep the methods I learnt from you low key. Your information and lessons are the most powerful tools in my arsenal."
James Olive
Agnes Water, QLD AustraliaLet's say you demonstrate to your boss your newly acquired, mobile hydraulics expertise and he gives you a raise of (only) $50 per week. Then you'll recover your entire investment in less than 10 weeks.
And if you think this kind of raise is unrealistic, think again. In the past few weeks alone I've heard from 2 of my students. One has just secured a raise of $320/week ($8/hr). And the other, $400/week ($10/hr). So don't ever underestimate the value of real, authentic hydraulics know-how. And the payback that comes from investing in yourself.
If on the other hand you're a hydraulic equipment owner, you only have to use The Definitive Guide to Mobile Hydraulics to help you solve just one problem and you'll likely recover your entire investment in full.
PLUS - you can spread the investment over 3 months - with our optional Equalizer Payment Plan, if you wish.
About that problem with the hydraulic excavator I described earlier. It was caused by a blocked orifice. Without a detailed understanding of the machine's hydraulic control system, you'd be hard pressed to even suspect this as a possible cause. Not until most of the hydraulic components had been replaced through guesswork anyway.
To the owner of this machine, someone (anyone!) who has the ability to quickly understand this machine's control system and then zero in on the cause of this type of fault, is worth his weight in gold.
The good news is this is a skill anyone can master. Anyone who wants to that is.
So, add this valuable skill to YOUR resume today.
Yours for better hydraulics knowledge,
Brendan Casey

P.S. #1. It's important to note that The Definitive Guide to Mobile Hydraulics may be tax deductible. Ask your tax advisor.
P.S. #2. If you don't get in on this mobile hydraulics training today, what WILL you do the next time you have a hydraulic problem to deal with? Will you openly admit you can't solve it because you don't understand the machine's hydraulic system? (This is probably the best strategy.) Or will you grope and guess, replacing one component after another until (hopefully) the problem goes away? (As you now know, this is a high risk strategy.)
The Definitive Guide to Mobile Hydraulics puts YOU in charge of the process. So don't put this off, respond now, before the deadline for this special offer expires this (if not before).
