Noise reduction in hydraulic systems often involves isolating the pump/prime-mover assembly using flexible mounts (isolators). In these cases, the use of hose is necessary to maintain the isolation between the pump/prime-mover and the rest of the system.

The flip-side to this though is, although long lengths of hose can reduce structure borne noise, hose is actually an efficient radiator in … Read more

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

The first member explains how he has just paid $10,000 for an old crawler tractor that needs works. He says: … Read more
