Good To Know

Q: Does this kit include wrist pin bearings or circlips? A: The kit includes the piston and rings, but wrist pin bearings and circlips may need to be sourced separately depending on the specific model.

Q: Is the cylinder ready to install or does it require machining? A: The cylinder is finished to standard bore size and should not require additional machining, but always measure ring end gap and piston clearance before assembly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
