CAT 054-6734 BUSHING

CAT 054-6734 is a Caterpillar genuine construction machinery articulated pin/eccentric shaft straight-tube bushing (pure original factory information, no additional description). It is compatible with Caterpillar 980F loaders, D350E/D400E articulated trucks, CB-334D/E and other vibratory rollers. It is used for radial support and wear reduction at articulated points/eccentric shafts, absorbing impact loads, compensating for installation errors, and extending the life of pins and supports (Cat®…).

Installation and Maintenance Points
**Before installation, clean the support hole and bushing outer diameter, ensuring no burrs or rust. Check that the bushing oil groove/lubrication hole is unobstructed, the alloy layer is not peeling off, and the steel back is not deformed.**
Use a dedicated pressing tool for smooth cold pressing, avoiding impact. Align the lubrication hole with the support oil passage, ensuring coaxiality ≤ 0.08 mm. After pressing, there should be no ellipticity.

After installation, measure the gap between the pin and bushing to 0.10-0.18 mm. Ensure there is no jamming during swinging/rotation. After a 15-minute trial run, check that the oil temperature is ≤ 80℃ and there are no abnormal noises.

Maintenance: Apply lithium-based grease (NLGI 2) every 500 working hours. Check the gap every 1500 hours. Replace the pin/support if the gap exceeds 0.30 mm or the alloy layer wear is > 0.5 mm to prevent accelerated wear.
