Replace the lift barrel with the improved barrel and seal-kit.

Refer to UENR3334, Disassembly and Assembly, "Lift Cylinder - Remove and Install", to remove and install the lift cylinder.

Refer to the Service Manual if/as necessary.

Note: Before assembly of cylinder, refer to the instruction below to inspect the status of setscrew on the piston.

Instruction for Setscrew Inspection:

1. Check whether the setscrew is loose or not, if loose, add Loctite 242, then tighten to a specified torque of 25 +/- 3 N.m.

2. Check the punched dimples around the hole for the setscrew. If the dimples don't make a deformation of thread of the hole, punch these dimples until the thread is deformed, which will prevents the setscrew from falling off after becoming loose.
