Good To Know

Q: Can I install this kit myself? A: Yes, you can rebuild the cylinder with basic hand tools, but you need to carefully clean the bore and install seals without nicking them. Torque the gland nut to factory spec.

Q: Will this kit solve a slow-drifting bucket? A: Yes, if drift is due to internal seal bypass, this rebuild repair kit will restore holding pressure. If drift persists, inspect the cylinder rod for scoring.
