(4) Install the anvil over the threaded end of the
main screw with the small end of the anvil against
the piston boss.
NOTE: Be sure spring is removed from anvil.
(5)
Install nut loosely on the main screw and place
the assembly on a press, as shown in Figure 107.
(6) Press the piston pin out of the connecting rod.
NOTE: When the pin falls free from the connecting
rod, stop the press to prevent damage to the bot-
tom of the anvil.
(7)
Remove the tool from the piston.
/nstal/ation
(1) Test the piston pin fit in the piston. It should
be a sliding fit in the piston at 70°F. Piston pins are
supplied in standard sizes only.
(2) Lubricate the piston pin holes in the piston and
connecting rod.
(3) Arrange the tool parts for installation
of the
piston pin, as shown in Figure 108.
(4)
Install the spring inside the pilot and install the
