Pushing installing tool into sleeve as far
as stop
- Remove the sleeve and slip it
onto the other end of the shank.
Note:
Pin must point toward flat
face of tool's shank.
- Apply the installing tool to the
piston boss, hold the piston
steady, center the tool shank
exactly and press home until the
snap ring slips into the groove.
- Push the slotted diameter of the
sleeve over the magnet and snap
ring so that the inner pin points at
the flat face of the tool's shank.
- Stand the installing tool, sleeve
downward, on a flat surface
(wooden board) and press
vertically downwards until the
sleeve butts against the tool's
shoulder.
Owing to the special shape of the
piston it is necessary to modify the
sleeve of the installing tool as shown
in the illustration.
Use the installing tool as follows:
- Remove the sleeve from the tool.
- Attach the hookless snap ring to the
magnet so that the snap ring gap is
on the flat side of the tool's shank
(see illustration).
