Figure 3-71. Removing Piston Pin Circlip
8. See Figure 3-71 . Remove the piston pin circlip as follows:
a. Insert the PISTON PIN RETAINING RING
INSTALLER (Part No. HD-34623C) into the piston
pin bore until claw on tool is positioned in slot of piston
(directly under circlip).
b. Squeeze the handles of the tool together and pull
from bore. In the event that the circlip should fly out,
hold a shop towel over the bore during removal.
Remove circlip from claw and discard.
NOTES
• It is not necessary to remove both piston pin circlips during
piston removal. Leave the second circlip in the pin bore.
• Since the piston pin is a loose fit in the piston, the pin will
easily slide out. The pin has tapered ends to help seat the
round retaining rings.
