3-1 Replacement of rod seal
Rod seal can be replaced while the cylinder is mounted. Replace by the following
procedure.
a) Removal
Remove retaining ring 1 using a specific tool (retaining ring pliers) and plug the port of
the rod cover with your finger. When the piston rod is removed, the seal holder 2 and
rod seal 3 will come apart.
b) Application of grease
Use our recommended grease.
Grease pack part number: GR-S-010 (10g), GR-S-020 (20g)
Apply plenty of grease to the internal and external circumference of a new rod seal
for replacement (See Table 4, P19). Fill the groove with grease.
Refer to Page 21 for made to order product (XC85, X446).
c) Mounting
Mount taking care that the rod seal is in the right direction. When passing the rod seal
through the threaded part at the piston rod end and wrench flats, push it slowly while
turning it slightly, and fit it firmly to the housing of the rod cover.
Then, mount the seal holder 2 and retaining ring 1.
