7S6875 Gear Gp-Hydraulic — Cat 955K 955L

This is a hydraulic gear group, a fundamental assembly within the hydraulic pump responsible for generating fluid flow through the meshing action of its gears. It is constructed from durable, wear-resistant materials to meet rigorous performance standards, offering extended service life over a worn or damaged gear set. Operators may experience reduced hydraulic system pressure, slow operation of hydraulic functions, or whining noises from the pump when this gear group fails.

Failure Symptoms

A failing hydraulic gear group often first manifests as a decrease in hydraulic system pressure and slower response from hydraulic functions. If the wear progresses, the pump may begin to make audible whining or grinding noises, and hydraulic performance will significantly degrade. Continued operation risks overheating the hydraulic system and damaging other sensitive components.

Installation Tip

Carefully align the gear teeth and ensure smooth rotation by hand before fully assembling the pump housing. Avoid introducing any dirt or debris into the gear mesh during installation.

Service Note

It is advisable to inspect the pump housing for scoring and wear, and to replace the hydraulic pump shaft seal if applicable, when installing a new gear group.
