CAT 095-4961 RETAINER

CAT 095-4961 (0954961) is a track retainer for the Caterpillar 400GT tracked chassis. It is compatible with heavy-duty equipment such as 349/352/374 excavators and 982/988 loaders. It works in conjunction with the 095-4213/095-4216 spring base and the 095-3812 track link. It is used to lock the tension spring, limit axial movement, and transmit tension force, and is a core positioning component of the track tensioning mechanism (Cat® Parts).

Item Details
Part Model CAT 095-4961 (0954961) Track Recoil Spring Retainer

Type: Track tensioning mechanism positioning and fixing part, with flange and positioning groove, compatible with 400GT track tension spring assembly, and matches with 095-4213/095-4216 spring base and 095-3812 track link.

Material: 42CrMo alloy steel, integral forging + quenching and tempering (HRC34-38), surface Carter’s yellow primer + wear-resistant coating, resistant to heavy-duty impact, fatigue, and corrosion.

Dimensions and Weight: Compatible with 400GT spring assembly, outer diameter approx. 170-190mm, flange diameter approx. 210-230mm, thickness approx. 28-35mm, single weight approx. 9-11kg, positioning groove precisely matches the spring outer diameter.

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

Function: Locks the track tension spring, restricts axial movement, transmits tension force, and works with the spring base to position the spring compression stroke, ensuring stable track tension and cushioning.

Adaptation and Application:
Adaptation Location: Front positioning point of the track tension spring assembly. Bolted to the spring base flange, it locks the spring’s axial position, works with the base to position the spring compression stroke, transmits tension force to the track links, and maintains stable track tension.

Application Scenarios: Heavy-duty working conditions such as mining and infrastructure construction. It withstands the impact and vibration of track movement, prevents tensioning mechanism failure caused by spring movement, avoids abnormal wear of track links and track rollers caused by excessively loose/tight tracks, and ensures stable operation of the walking system.

Core Functions: Locks the spring, restricts axial movement, transmits tension force, works with the base to position the spring stroke, cushions impact, protects chassis components, and extends the service life of the track system.

Installation and Maintenance Points

Installation: Clean the connecting surfaces and tighten the bolts to the original torque of 350-400 N·m; check the matching degree between the positioning groove and the spring to ensure that the spring has no axial movement and that the track tension meets the requirements of the equipment manual.

Maintenance Cycle: Check for deformation, cracks, and bolt torque of the fixing device every 500 hours. In harsh working conditions such as mining, this period can be shortened to 200 hours.

Replacement Standard: Replace the track if cracks, deformation, wear of the positioning groove, or failure to lock the spring/transmit tension force is found. Original parts are preferred to avoid tension failure and track misalignment due to size/strength issues.
