Transmissions

Hydraulic pressure was supplied by a pump integral with the gearbox giving 68-72lb/in2 for early models and up to 87-91lb/in2 later. This oil supply was filtered only by a gauze filter and was susceptible to fine contaminants entering the system that could result in the relief valve sticking in the open position.

How to solve hydraulic system overheating problems

Hydraulic oil temperatures above 180°F (82°C) damage most seal compounds and accelerate degradation of the oil. While the operation of any hydraulic system at temperatures above 180°F should be avoided, oil temperature is too high when viscosity falls below the optimum value for the hydraulic system's components.

Gear Oil Issues

Gear Oil Level Too High. The opposite of a leak is having the gear oil level too high. This can happen when hydraulic oil leaks into the gearbox. One potential cause is a worn oil seal or bearings. If this is the case, they would need to be replaced as soon as possible.

Controlling Hydraulic Oil Temperatures

Consider that for every 18-degree increase in temperature above 140 degrees, the life of the oil is cut in half. Systems that operate at high temperatures can produce sludge and varnish, which result in the sticking of valve spools. Pumps and hydraulic motors bypass more oil at high temperatures, causing the machine to operate at a slower speed.
