Item Details
Part Model CAT 095-3812 (0953812) Track Link

Type Track link connecting rod with pin holes and bolt holes, used to connect track links and track shoes, transmitting driving force and lateral load, compatible with 400GT track chassis

Material 42CrMo alloy steel, integral forging + tempering heat treatment (hardness HRC36-38), surface anodized black / Caterpillar yellow primer, impact resistant, fatigue resistant, corrosion resistant

Dimensions and Weight Compatible with 400GT track shoe width (approx. 400mm), length approx. 200-230mm, width approx. 85-105mm, thickness approx. 30-35mm; single weight approx. 8-10kg, pin hole/bolt hole spacing matches track link and track shoe mounting holes

Compatible Models 349, 352, 374 This product is suitable for medium and large excavators, 982 and 988 heavy-duty loaders, etc., and is compatible with the 400GT tracked chassis. It is compatible with chassis components such as 095-2943 track shoes, 095-3460 track retainers, and 095-3609 oil seals and retaining rings.

Functional Positioning: Connects track links and track shoes, transmitting driving force and lateral load, ensuring stable operation of the track system; works with track retainers to prevent track shoe misalignment, protects track links, track rollers, and guide rollers, and extends the service life of chassis components.

Compatibility and Application: Suitable for the connection points between track links and track shoes. Secured by pins and bolts, it connects track links and track shoes, transmitting driving force and lateral load, meeting the connection requirements of the 400GT track shoes.

Application Scenarios: Suitable for heavy-duty working conditions such as mining and infrastructure construction, bearing longitudinal driving force (commonly 10-20 tons) and lateral impact loads of the track, ensuring the stability of the track system during high-speed travel, turning, and heavy-duty operations, and preventing track pad detachment that could lead to equipment failure and safety accidents.

Core Functions: Connects track links and track pads, transmitting driving force and lateral loads; works with retainers to prevent track pad misalignment, protecting track links, track rollers, and guide rollers, extending the service life of chassis components.

Installation and Maintenance Points:

Installation: Clean the connecting surfaces of the connecting rods, track pads, and track links, ensuring they are free of oil and impurities; tighten bolts to the original torque (250-300 N·m, refer to the model manual); after installation, check the connecting rod positioning and lateral clearance of the track pads to ensure there is no track pad misalignment or jamming.

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

Replacement criteria: If the connecting rod has cracks, deformation, worn/deformed bolt holes, or worn pin holes causing track slippage, it must be replaced; original parts are preferred to avoid track slippage detachment, misalignment, and other malfunctions caused by dimensional deviations/insufficient material strength.
