2. OAD Pulley Seal Cap - Remove

1.
Remove the OAD pulley seal cap (A) by piercing the center of the rubber cap with a flat screwdriver and prying it loose.

1. OAD Pulley - Inspect


1.
Clamp the alternator firmly in a vise.

2.
Insert the alternator OAD pulley holder into the OAD pulley.






3.
Place a beam type torque wrench (A) with a 17 mm socket wrench (B) on the alternator OAD pulley holder.

4.
While holding the OAD pulley (C), rotate the alternator shaft counterclockwise. Make sure the alternator shaft is locked when applying the specified torque.

Specified Torque:
11 N·m (1.1 kgf·m, 8 lbf·ft)

If the alternator shaft locks, go to step 3.
If it does not lock, replace the OAD pulley.





5.
While holding the OAD pulley (A), rotate the alternator shaft clockwise. Check that the alternator shaft rotates at the specified torque or less.

Specified Torque:
0.8 N·m (0.08 kgf·m, 0.6 lbf·ft) max

If the alternator shaft rotates at the specified torque or less, it is normal. Install a new OAD pulley seal cap.
If it does not rotate at the specified torque or less, replace the OAD pulley.
