REPLACING/REPAIRING
NOTES:
•
Inspect the rubber iso mounts (P/N 2351-1) for
cracking or signs of deterioration and replace as
needed. Good preventative maintenance would
recommend replacing the rubber mounts at the
same time as the alternator belt.
•
When installing the bolts into the rubber iso
mounts, make sure the flat washer and star lock
washer are in place on each bolt.
•
Use Loctite 242 (Blue) Threadlocker compound
(or equivalent) on each bolt.
•
Install all twelve (12) of the rubber iso mount bolts
and tighten only finger tight before tightening any
bolts with a wrench.
