REMOVAL SERVICE POINTS
<<A>> TIMING BELT REMOVAL
AK500721
1. Using chalk, etc., mark an arrow on the back of
the timing belt to indicate the direction of rotation.
This is to ensure correct installation of the belt in
case it is reused.
<<B>> AUTO TENSIONER REMOVAL
Keep the auto-tensioner longitudinal. If it were kept
lateral, it would possibly cause aeration.
<<C>> PUMP SPROCKET REMOVAL

1. Use the special tool Injection pump sprocket
holder (MB992048), hold the pump sprocket.
CAUTION
Never strike the shaft or sprocket to remove the
sprocket. This may cause malfunction in the
injection pump. Be sure to use a puller to remove
the sprocket.
2. Remove the pump sprocket nut.

• Crank pulley puller (MB992099)
<<D>> CRANKSHAFT SPROCKET REMOVAL
AK404172 AB
MD998778
Use the special tool Crankshaft sprocket puller
(MD998778), if the sprocket is stuck and hard to
remove.
<<E>> TIMING BELT "B" REMOVAL
AK404168
Using chalk, etc., mark an arrow on the back of the
timing belt to indicate the direction of rotation. This is
to ensure correct installation of the belt in case it is
reused.
NOTE: Water or oil on the belt shortens its life drasti-
cally, so the removed timing belt, sprocket, and ten-
sioner must be free from oil and water. Do not
immerse parts in cleaning solvent.
NOTE: If there is oil or water on any part, check front
case oil seals, camshaft oil seal and water pump for
leaks.
