pattern relative to its running direction, if
the original belt is to be re-used it must be
refitted so that it rotates in the original direction.
CAUTION: Belts must be stored on edge
on a clean surface and in such a manner
that bends are not less than 50 mm radius.
Do not bend belts at an acute angle or radius of
less than 50 mm, otherwise premature failure
could result.

tensioner plate.
NOTE: Belt tensioning should be carried
out using a dial type torque meter having a
range not exceeding
60 Nm.The torque
meter should be used in the almost vertical
position.
35.Apply a tension of
14 to 16 Nmfor a new belt or
11 to 13 Nmfor an original belt. When tension
is correct tighten clamp bolt.
36.Tighten injection pump gear bolts.
