Alternator Pulley: Service and Repair
Preliminary work:
Generator removed, See: Service and Repair
Collar nut (1)
unscrew, screw on, tightening torque 80 Nm.
Use socket (10 mm) with internal serrations together with reversing ratchet to hold the shaft (2).
Poly V-belt pulley (3)
take off, fit on.
The poly V-belt pulley (3) is subject to very diverse stresses. The level of the stresses depends primarily on driving conditions. For this reason, when
reconditioning generators after mileages of more than 60,000 (100,000 km) also renew the poly V-belt pulley (3).
