CAT 095-3989 RETAINER

CAT 095-3989 (0953989) is a track shoe retainer for the Caterpillar 400GT tracked chassis. It is compatible with 349/352/374 excavators, 982/988 loaders, and other equipment. Installed at the connection between the track link and the track shoe, it locks the track shoe in place, preventing it from loosening, shifting, or falling off under heavy load/impact conditions. It is a critical fastener for the stable operation of the tracked chassis’s running gear.

Compatible Models CAT 349, 352, 374 excavators, 982, 988 For loaders and other applications, this product is compatible with the 400GT tracked chassis and includes chassis components such as 095-2943 track shoes, 095-3812 track links, and 095-3609 oil seals/retaining rings.

Functional Positioning: Locks the track shoes to prevent loosening, shifting, or detachment under heavy load/impact conditions; positions the track shoes laterally to reduce impact wear between the track shoes and track links, extending the service life of the track system.

Compatibility and Application:
Compatible Locations: The connection point between the track shoes and track links. Secured with bolts, the track shoes are locked to prevent loosening, shifting, or detachment during travel, turning, and heavy-load operations.

Application Scenarios: Suitable for heavy-load conditions in mining, infrastructure, and other applications. It withstands lateral impact loads on the tracks, ensuring the stability of the track system during high-speed travel, turning, and heavy-load operations, and preventing track shoe detachment that could lead to equipment failure and safety accidents.

Core Functions: Locks track shoes to prevent loosening, shifting, or detachment; positions track shoes laterally to reduce impact wear between track shoes and chain links, extending track system lifespan and reducing equipment maintenance costs and downtime.

Installation and Maintenance Points
Installation: Clean the connection surfaces of the retainer and track shoes/linkage rods, ensuring they are free of oil and impurities; tighten bolts to the original torque (200-250 N·m, refer to the model manual); after installation, check the positioning of the retainer and the lateral clearance of the track shoes to ensure there is no track shoe shifting or jamming.

Maintenance Cycle: Check the retainer for deformation, cracks, and bolt torque every 250 hours; shorten this to 100 hours in harsh working conditions such as mining.

Replacement Standard: The retainer must be replaced if it shows cracks, deformation, worn/deformed bolt holes, or is unable to lock the track shoes; original parts are preferred to avoid track shoe detachment, misalignment, and other malfunctions caused by dimensional deviations/insufficient material strength.
