Work clean—protect the new sleeve from debris; contamination will damage the bore quickly.
Inspect the piston/rod and packings; replace worn components at the same time for best results.
Torque fasteners to spec and verify concentricity/alignment during reassembly.
After installation, pressure-test and monitor for abnormal heat or bypass.

Frequently Asked Questions
