Tappet, Main Bearing, and O-Ring Removal
(1)
Remove the hydraulic tappet plungers using the Tappet Assembly Tool P/N 64941.
CAUTION
IF A TAPPET ASSEMBLY TOOL IS NOT AVAILABLE, REMOVE THE
PUSH ROD SOCKETS BY HAND OR BY MAKING A LOOP FROM A
SHORT LENGTH OF SAFETY WIRE. DO NOT USE A MAGNET TO
REMOVE THE SOCKET OR THE PLUNGER ASSEMBLY FROM THE
ENGINE, AS THIS COULD CAUSE THE BALL TO REMAIN OFF ITS
SEAT AND MAKE THE UNIT INOPERATIVE.
(2)
Remove the push rod socket (Figure 11) by placing heavy grease on the ball end of the
Tappet Assembly Tool. Push the greased ball end of the Tappet Assembly Tool into the
socket and withdraw it. The socket will adhere to the grease.
