the diameter of the shaft to determine the
clearance between the two. If the clearance
exceeds the service limit, replace the idler gear
or shaft.

(3) Removing idler gear shaft
To remove the idler gear shaft for replacement,
use idler shaft puller (MH061077).
Crankshaft pulley
Check the V-belt groove for wear. Wrap a new belt
around the pulley, pressing it in the groove as far as
it goes, and see if the top surface of the belt is above
the top of the pulley.
If the top surface of the new belt is uniformly above
the top of the pulley all the way around, it is not
necessary to replace the pulley.
If the top surface of the new belt sinks into the groove
more than 1.6 mm [0.06 in.], replace the pulley.
