1. Abrasive wear is the scuffing and scoring of a lubricated surface. It can be further divided into two-body abrasion and three-body abrasion. Two-body abrasion occurs when two lubricated surfaces come into direct contact with each other–usually as a result of loss of the lubricating oil film. Three-body abrasion occurs when the clearance between two lubricated surfaces is bridged by … Read more
The issues which can arise when switching brand and/or type of hydraulic oil, is a question I get a lot. And the crux of this problem, is:
1. You can never completely drain ALL of the original oil out of the hydraulic system; and therefore:

The objective of flushing a hydraulic system is to eliminate sludge, varnish, debris and contaminated or degraded fluid from conductor walls and other internal surfaces and system dead spots.
Reasons for performing a system flush include:
1. Fluid degradation – resulting in sludge, varnish or microbial deposits.
2. Major failure – combined with filter overload, which disperses debris throughout the … Read more
