Good To Know

Q: Do I need to remove the cylinder to install this seals kit? A: In most cases the lift cylinder is removed and disassembled on a bench so the seals can be seated cleanly. Follow the service procedure for your machine to avoid damaging the new seals.

Q: How do I know this kit matches my cylinder? A: Confirm your machine model and existing cylinder part number against 6803329 and 7137769 before ordering. Serial number breaks can change which seals are used, so verify first.

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