INSPECTION AND REPAIR CONTINUED
Bluing of any part of fan mounting assembly is a sign of excessive heat. This heat can
weaken bonding of rubber member. Anytime this happens, strength of bonding must be
checked as follows:
6. Clamp pulley in fabricated holding fixture (WP 0125), install fabricated fan pulley torque fixture (WP 0125) in
keyway of coupling flange and torque to 1,800 to 2,000 lb-ft (2,450 to 2,700 Nm).
7. If any slippage occurs between coupling and pulley, part must be replaced.
8. If necessary, fabricate fan pulley holding fixture (WP 0125).
9. If necessary, fabricate fan pulley torque fixture (WP 0125).
