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.
3. Slide the receiver cup KDAW 9995/0/5 (Bosch Number 0 986 619 250) onto threaded rod.
4. Screw on the handle, rotate until the bearing, and seal come out of the collector end shield. (Figure 16)
