CAT 095-6848 INNER RETANR

CAT 095-6848 (0956848) is an internal retaining ring for the track tensioning cylinder of the Caterpillar 400GT. It is compatible with models such as the 349/352/374/395 excavators and the 982/988 loaders. It works in conjunction with the 095-6768 lower bearing cap, 095-6769 upper bearing cap, 095-6429 retainer, and 095-6657 spring retaining ring. Its core function is to axially position the internal bearings and sealing components of the tensioning cylinder, preventing component movement under high pressure conditions and ensuring stable operation of the track tensioning system. It is a key axial positioning component of the track tensioning mechanism (Cat® Parts).

Item Details
Part Model CAT 095-6848 (0956848) Internal Retaining Ring

Type: Flexible internal retaining ring for bores, compatible with 400GT track tensioning cylinders, and used with 095-6768/095-6769 bearing caps and 095-6429 retainers

Material: 65Mn spring steel, integrally quenched and tempered, hardness HRC42-48, good elasticity and fatigue resistance, suitable for operating conditions from -40℃ to 120℃

Key Dimensions: Free inner diameter approx. Ø100-110mm, thickness approx. 3-4mm, slot width approx. 3.2-3.5mm, unfolded outer diameter approx. Ø115-125mm, opening clearance approx. 5-6mm

Compatible Models: CAT 349, 352, 374, 395 Excavators, 982, 988 loaders, and other 400GT tracked chassis equipment.

Functional Positioning: Axially positions the internal bearings and seals of the tension cylinder, bearing an axial load ≤50kN, preventing axial movement of components, and ensuring stable operation of seals and bearings.

Compatibility and Application:
Compatible Parts: Installed in the groove on the inner wall of the track tension cylinder, mates with the 095-6768 lower bearing cover and 095-6769 upper bearing cover, axially positioning the lower bearing, upper bearing, and sealing components, preventing component displacement under high pressure, and ensuring stable transmission of tension force to the track.

Application Scenarios: Heavy-duty, high-frequency working conditions such as mining and infrastructure construction, bearing track tension force and ground impact, preventing axial movement of bearings and seals that could lead to wear, seal failure, excessively loose/tight tracks, and track deviation.

Core Functions: Axial positioning, anti-movement, extending bearing and seal life, and reducing maintenance frequency.

Installation and Maintenance Points

Installation: Use special retaining ring pliers to pry open the retaining ring and insert it into the groove on the inner wall of the cylinder, ensuring it is completely locked into the bottom of the groove; ensure it fits snugly against the bearing end face, with an axial clearance ≤0.05mm to avoid uneven bearing wear.

Maintenance Cycle: Check the retaining ring for deformation, breakage, and elasticity decay every 1000 hours. In harsh working conditions such as mining, this period should be shortened to 500 hours.

Replacement Standard: The retaining ring must be replaced if it is deformed, broken, lacks elasticity (cannot be reset after prying), or the groove fit clearance is >0.1mm. Original parts are preferred to avoid positioning failures or component movement caused by dimensional/material deviations.
