Dampening Resistor Testing And Removal; Removal Of Collector End Shield Bearing And Seal - Bosch T1 Alternator Repair And Testing Instructions

9.9 Dampening Resistor Testing and Removal

1. The W Terminal incorporates a dampening resistor. Using a Multimeter MMD 302, connect one lead to the
exterior portion of the W terminal and connect the other lead to the other side of the W Terminal. The
Multimeter should read between 3.1 and 3.5 k (kilohm). If the resistance is above or below this range, the
W terminal is to be replaced as an assembly. (Figure 15)
2. Loosen the nut retaining terminal W to the collector end shield.
3. Remove terminal W.

9.10 Removal of Collector End Shield Bearing and Seal

1. Insert extractor KDLJ 6009 (Bosch Number 0 986 618 121) into bearing.
2. Screw threaded rod KDAW 9995/14 (Bosch Number 0 986 618 214) into extractor KDLJ 6009.
