CAUTION
Always use new retaining ring. Make sure retaining ring
groove is clean and that ring seats firmly in groove. If it
does not, discard the ring. Never install a used retaining
ring or a new one if it has been installed and then
removed for any reason. A loosely installed ring will
come out of the piston groove and damage cylinder and
piston beyond repair.
3. Install new piston pin retaining rings with the
PIN RETAINING RING INSTALLER (Part No. HD-
34623A). Make sure the ring groove is clean and that the
ring is fully seated in the groove with the gap away from
the slot at the bottom.

properly positioned as shown.
