Brendan Casey,
hydraulics author, educator and publisher.

Dear mobile hydraulics user or 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, read on 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...

PRINCIPLES Are the Key To Making the Complex Simple

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 all of these principles are explained in my NEW book: The Mobile Hydraulics Handbook.

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 book is especially for you. And it's one you should definitely own. Because 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.

Each of its 14 chapters begins with a review of the fundamentals, and from there moves quickly into the advanced aspects of mobile hydraulic control. 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 chapter 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 chapters.

And while proportional and electronic control are covered in detail, a BIG chunk of this handbook 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 pump and motor controls explained in each of these four, very important chapters:

Variable pump control

Pressure, flow and power control.
Proportional electro-hydraulic displacement control (e.g. Liebherr, O&K, Case, etc).
Positive hydraulic displacement control (e.g. O&K, Hitachi, Demag, etc).
Negative hydraulic displacement control.
Power summation; semi cross-sensing.
Power summation; full cross-sensing (e.g. CAT, Komatsu, Hitachi, etc).
Pressure control of multiple pumps in parallel.

Load sensing systems

Open center load sensing (e.g. CAT, Komatsu, Hitachi, etc.).
Closed center load sensing (e.g. CAT, Komatsu, Case, etc.).
Fixed pump load sensing.
Pre and post-compensation.
Anti-saturation.
Load signal amplification.
Differential pressure limitation.

Variable motor control

Constant pressure control.
Hydraulic displacement control.
Two position 'flip-flop' control.
Hydraulic control; speed dependant.

Hydrostatic transmissions

Stepless displacement control of pump and motor (e.g. Liebherr dozers).
Constant output torque control (e.g. Liebherr, O&K, etc.).
Mooring control (of a constant tension winch).
Speed dependant (automotive) control (Rexroth's 'DA' control, e.g. Linde forklifts).

As I've mentioned already, each of the 14 chapters in this specialized handbook 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 Mobile Hydraulics Handbook is not ONLY about variable pump, motor, load sensing and hydrostatic transmission controls. Here's a taste of what else is in store:

	IF YOU DON'T WANT TO LOOK LIKE A DUNCE, don't act like one. If these 10 truths about hydraulic machines aren't second nature to you, there's a good chance you'll end up with egg on your face.
	How to exploit the 'optical illusion' used by artists, to make immediate sense of the most complex hydraulic drawings.
	The real (21st century) meaning of digital control.
	The difference between open center and open return. And why you need to know about it.
	Two types of pressure control valve that pop up everywhere on mobile hydraulic drawings. And why you can't ignore them.
	The 3 ways mobile DCV sections are connected internally and what you must understand about each of them.
	How to make sense of the sneaky trick system designers use to rectify alternating flow.
	What you must ALWAYS double check BEFORE changing-out a directional control valve.
	The practical differences between the 3 main types of load control valve. And what you must be absolutely sure of BEFORE you reach for an Allen key.
	There are two ways to install chokes on a pilot operated DCV. If you don't know the simple rule explained on page 86 you've only got a 50% chance of getting it right.
	Two types of flow control valves that are often confused with each other. And how to make sure this mistake doesn't happen to you.
	A spool-type flow divider can't intensify pressure downstream. Or can it?
	The simple shortcut to understanding load sensing control (skip over this and you'll likely struggle).
	What to watch out for when using a power beyond facility.
	The 7 most common uses of logic elements. And how to quickly recognize each of them.
	A little known problem that quietly destroys a hydrostatic transmission.
	Why you should NEVER connect 'supply' voltage to a proportional solenoid. Not even in an emergency.
	How a variable pump's electro-proportional stroke limiter can function as its pressure cut-off.
	How a pressure compensated pump can actually create MORE heat than its fixed displacement counterpart.
	One practical reason why 'high-end' servo valves sometimes find their way into 'low-tech' mobile hydraulics applications.
	How a logic element can seal like a poppet valve, or leak like a spool valve.
	The simple trick which adds remote pressure control to any load sensing pump.
	The secrets of motor brake sequencing. And a problem that can arise in brake sequencing circuits on hydrostatic transmissions.
	How a hydraulic load signal amplifier works.
	The two main types of pump power summation control. And why one is far superior to the other.
	A common problem with multiple, pressure compensated pumps connected in parallel. PLUS, its 3 solutions.
	The pros and cons of load reaction and non-load reaction steering systems. And how they both work.
	Why closed center load sensing is better than open center load sensing. And how to quickly distinguish between them.
	The simple but amazing difference between a differential pressure limiter and a relief valve.
	Two popular methods for eliminating flow starvation and function stall on mobile hydraulic machines. And why one is preferable to the other.
	The right way to set up a transmission valve. Get this wrong and you'll cook the system.
	Beyond brake sequencing. How a 'pressure memory' switch works.
	How to recognize phasing cylinders when you see them. And their most common applications.
	The correct way to set a variable pump's pressure cut-off and relief valve, and why.
	Filters, filters everywhere. THE single most important filter location on a hydrostatic transmission.
	How a DCV with an open center inlet section CAN be used with a variable displacement pump (in closed center).
	What do an orbital steering unit and a servo valve both have in common? Page 227 explains.
	How an anti-saturation valve works.
	Better than a cross line relief valve. How pressure override works on a hydrostatic transmission pump. PLUS, how it's used for 'mooring control'.
	CAUTION: what you must always look for when there's an accumulator installed. And it's not what you might think.
	The difference between positive and negative displacement control. PLUS, how the wrong start of control setting can HOODWINK you into changing out a perfectly good pump.
	If you are now a "B" or "B+" technician, learning this one, little-known technique will catapult you towards the ranks of "A" or even "A+" technicians, who always get first pick of the best jobs.

This handbook contains A STACK of mobile hydraulics know-how. It comprises 260, A4 pages (8.3" x 11.7"), so it's just not possible to list all the knowledge you'll gain, here. But at least now you have a good idea.

27 Years Of Mobile Hydaulics Know-How

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 Mobile Hydraulics Handbook lays it all out in front of you in an easy to understand format.

I only wish a book like this 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?

Because to the victor go the spoils...

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.

So What's a Book Like This Worth?

How much should you expect to invest to own such a book? Well firstly, The Mobile Hydraulics Handbook is not the sort of book you can value by the page or pound. Because if you use it to help you solve just one hydraulics problem, it's sticker price is utterly irrelevant.

That said, I personally spend thousands of dollars every year adding to my own technical library, and I've got one of the most extensive private hydraulics libraries around. Based on what I've paid for similar books, the right price for The Mobile Hydraulics Handbook is around the $165 mark.

But I'm not asking this much. Nowhere near it. Reason being, this is NOT a book for academic types wearing thick glasses and white coats. It's a book for guys who work at the 'coal face'. Guys who are used to getting oil on their hands. And for this reason I want to make it accessible to as many of these folks as possible.

Which means if you get your copy of The Mobile Hydraulics Handbook today, it's yours for only $129.00. That's a saving of $36 on what you'd pay for a comparable book (not that there are any comparable books covering advanced mobile hydraulics).

Now let me break it down for you

Even though there aren't any other books that deal with advanced mobile hydraulics in the way The Mobile Hydraulics Handbook does, a similar technical book can set you back $165. PLUS you get the Relay and PLC Logic ebook and one month's membership to Hydraulics Pro Club - together a $45 value. Add to this FREE shipping - to anywhere in the world - a $30 value... and this comes to $240 total.

I have great news for you ...

You DO NOT need to invest $240 to become a high-paid and in-demand mobile hydraulics expert. Nor do you need to spend 27 years trying to figure this out for yourself (like I did!).

Because if you're one of the FIRST 7 to respond before midnight this I'm willing to give all this away to you for only $129.00.

So basically, I just gave you a $111.00 discount on what it would cost you if you COULD get all this mobile hydraulics know-how somewhere else. (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 $129? On a one-time only basis, not much. 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 material. 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 wealth of mobile hydraulics knowledge 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 knowledge to benefit from The Mobile Hydraulics Handbook. 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 chapter begins with a review of the fundamentals, upon which the more advanced concepts are built.

"I prefer to work in Metric rather than US units (or vice versa)"

Both US and Metric units are used throughout (it's good to be familiar with both). But this isn't a big issue either way bcause 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 handbook will not be entirely new to you. But The Mobile Hydraulics Handbook 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 handbook 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"

There is NO other book that explains the advanced mobile control concepts covered by this one. Believe me, I've looked far and wide.

"I already have The Definitive Guide to Mobile Hydraulics. How is The Mobile Hydraulics Handbook different?"

The Mobile Hydraulics Handbook is a slimmed-down, no-frills version of The Definitive Guide to Mobile Hydraulics training package. You don't get the 8-1/2 hours of simulation videos and study-guide, or the one-on-one, coaching/tutorial support with me. In other words, 'The Definitive Guide' is the 'Rolls-Royce' version of this mobile hydraulics training, and it's still available here.

But what you DO get with The Mobile Hydraulics Handbook is complete explanation of the principles and procedures that will transform you into a high-paid and in-demand mobile hydraulics specialist, no matter what your level of experience. AND it's presented in a convenient format you can easily carry around in your toolbox or in the glove compartment of your van or truck.

"I live beyond Siberia, so shipping will be too expensive"

If you act promptly, worldwide shipping is included in the FREE bonsues, 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"

Let'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 3 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 Mobile Hydraulics Handbook to help you solve just one problem and you'll recover your entire investment many times over.

"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."

An Investment In Success

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,

P.S. #1. It's important to note that The Mobile Hydraulics Handbook may be tax deductible. Ask your tax advisor.

P.S. #2. If you don't get in on this today, what WILL you do the next time you have a mobile hydraulics 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 Mobile Hydraulics Handbook 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).
