Installation and Fitting Points
Clean the mounting holes and pins, removing burrs and rust. Mounting hole roughness Ra≤1.6μm, pin roughness Ra≤0.8μm.

Cold press-fit the bushing with a pressing force of 10–15 kN. Hot fitting is prohibited.

After installation, the clearance between the inner hole and the pin should be 0.040–0.065 mm, with no axial movement of the bushing.

Apply lithium-based grease to the inner hole before assembly.
