Structural Features: Flanged straight cylinder structure, single oil groove with double oil holes (suitable for manual/centralized lubrication), rated radial load 45kN, operating temperature -30℃ to 120℃, static radial clearance 0.015-0.025mm

Compatible Structures: Suitable for pin diameter 50.80mm, mounting hole diameter 63.50mm, installation interference 0.018-0.028mm

Applicable Working Conditions: Rotating parts of the working device, speed ≤500rpm, radial load ≤35kN

Compatible Machines and Assemblies:

Loaders: CAT 966H, 972H (boom and rocker arm bushing assembly)

Excavators: CAT 324D, 326D (stick and connecting rod bushing assembly)

Compatible Assemblies: 966H boom and rocker arm bushing assembly, 324D Stick Connecting Rod Bushing Assembly Installation and Fitting Points: Before installation, clean the mounting holes and the outer diameter of the bushing. Use a special press to cold-press it in place. Do not strike the end face to prevent deformation.

After installation, ensure an interference fit (0.018-0.028mm) and a clearance fit (0.015-0.025mm) with the pin to ensure smooth and unobstructed rotation.

After assembly, check the coaxiality to be ≤0.02mm. Apply lithium-based grease promptly after installation.

For disassembly, use a special puller to remove the bushing. When replacing, check the pin and mounting hole for wear. If the wear is >0.05mm, repair or replacement is required.
