Checking the Belt-Pull
Bumper
Note:
Check the belt-pull bumper only when
troubleshooting vibration, performing a rebuild, or
experiencing an engine-mount failure.
The belt-pull bumper ( Figure 57 ) should maintain a
gap of 2.2 mm (0.09 inches).
If the bumper is too close to the engine bracket, the
belt causes excessive vibration; if the bumper is too
far from the engine bracket, the belt causes harmful
engine stress.
To adjust the gap, loosen the 3 flanged-head bolts
securing the bracket to the frame and slide the bracket
the appropriate distance.
Once the gap is correct, tighten the 3 flanged-head
bolts.
