How To...REMOVE AND REPLACE THE ALTERNATOR
Tools Required: 3/4, 5/16, 1/2, and 1/4 inch wrenches.
STEP 1
Remove the HOUSING. Refer to “How To...” in this section.
STEP 2
Remove the two POSITIVE RED WIRES from their
POSTS on the ALTERNATOR. Using a 1/4 inch wrench,
remove the two nuts securing the BLACK FIELD WIRE and
the YELLOW WIRE. Then with a 5/16 inch wrench, remove
the REGULATOR TERMINAL NUT and the GROUND
TERMINAL NUT.
STEP 3
With a 1/2 inch wrench, loosen and remove the
ALTERNATOR ADJUSTMENT BOLT and two WASHERS.
STEP 4
With two 3/4 inch wrenches, loosen the ALTERNATOR
PIVOT BOLT and LOCKNUT. DO NOT remove the
ALTERNATOR until STEP 7.
STEP 5
Push the ALTERNATOR forward to relieve the belt tension, then loop the BELT around the small FLYWHEEL
SHAFT. Once the BELT is free, temporarily set it on top of the PULLEY to keep it out of the way.
STEP 6
Remove the PIVOT BOLT and its three WASHERS from the ALTERNATOR.
STEP 7
Remove the ALTERNATOR and install the new ALTERNATOR in place.
STEP 8
Reverse this procedure for reassembly using specified torques, however note the following:
NOTE: THE ALTERNATOR BELT MUST BE PROPERLY POSITIONED ON THE LARGE PULLEY AND
ALTERNATOR FLYWHEEL. MISALIGNMENT WILL RUIN THE BELT AND PULLEY.
NOTE: USING A BELT TENSION GAUGE, MEASURE THE BELT TENSION. IF THE BELT TENSION
MEASURES LESS THAN 60-70 LBS., MAKE ADJUSTMENTS USING
THE ALTERNATOR ADJUSTMENT BOLT.
