Installation and Fitting Points
Shaft groove diameter: 28.00+0.05/-0.00 mm, groove width: 1.60+0.10/-0.05 mm, groove depth: ≥1.50 mm, groove wall burr-free, chamfer ≤0.2 mm.

Use special retaining ring pliers to pry open the retaining ring and smoothly place it into the shaft groove, ensuring the retaining ring is fully embedded in the bottom of the groove without any warping or skewing.

After installation, the outer circle of the retaining ring should be flush with or slightly lower than the shaft surface, with adjacent parts end faces fitting together without axial movement.

Before installation, clean the shaft groove and retaining ring, ensuring they are free of oil and rust. Inspect the retaining ring for cracks, deformation, and peeling plating.

For disassembly, use snap ring pliers to clamp both ends of the opening and slowly retract to remove it. Do not pry forcefully to avoid breaking the retaining ring or damaging the shaft groove.
