Frequently Asked Questions
This cylinder is specified for a 2.50 in (approx) internal diameter for the motor assembly it supports.
Re‑use is not recommended; OEM cylinders are machined to precise tolerances and polishing may not restore original specs.
Look for scoring, change in bore diameter, piston play or fluid bypass as key indicators of cylinder wear.
