CAT 095-4149 RETAIN UPPER

CAT 095-4149 (0954149) is an upper track shoe retainer for Caterpillar 400GT tracked chassis. It is compatible with heavy-duty equipment such as 349/352/374 excavators and 982/988 loaders. Installed at the connection between the track link and the upper side of the track shoe, its core function is to lock the upper side of the track shoe in place, preventing it from loosening, shifting, or falling off under heavy loads and impact conditions. This ensures the stable operation of the tracked running system and is a critical fastener for the tracked chassis.

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

Functional Positioning: Locks the upper part of the track shoes to prevent loosening, shifting, or detachment; 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 Location: The upper connection point between the track shoes and track links. Secured with bolts, the upper part of the track shoes is locked to prevent loosening, shifting, or detachment during travel, turning, and heavy-duty operations.

Application Scenarios: Suitable for heavy-duty 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-duty operations, preventing track shoes from detaching and causing equipment failure and safety accidents.

Core Functions: Locks the upper part of the track pads to prevent loosening, shifting, or detachment; positions the track pads laterally to reduce impact wear between the track pads and chain links, extending the track system’s lifespan and reducing maintenance costs and downtime.

Installation and Maintenance Points

Installation: Clean the connection surfaces of the retainer and track pads/links, ensuring they are free of oil and impurities; tighten the 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 pads to ensure there is no track pad 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 cannot effectively lock the track pads; original parts are preferred to avoid track pad detachment, misalignment, and other malfunctions caused by dimensional deviations or insufficient material strength.
