Installation and Fitting Points
**Before installation, clean the cylinder block groove and retainer. Use flexible retainer pliers to expand the cylinder block groove before inserting it. Do not pry hard to avoid deformation.**
**After installation, ensure it fits snugly against the bottom of the cylinder block groove. The flange should engage with the dust cover positioning groove. The retainer and cylinder block should have an interference fit (0.008-0.015mm). The dust cover should not be loose.
After assembly, check that the radial runout is ≤0.020mm, and that there is no interference between the dust cover and the retainer edge, ensuring smooth piston reciprocating motion.
For disassembly, use a special puller to remove the cylinder block. When replacing, check the cylinder block groove for wear. If the wear is >0.04mm, repair or replace the cylinder block.
