c.
Each measurement in step b should be approximately equal. If difference is great between any two readings,
replace stator (22).
ASSEMBLY
1.
If removed, install new slidable bushing (64).
CAUTION
If either rotor half has been damaged, both rotor halves must be replaced. Failure to replace both will cause
rotor to be out of balance and alternator will not operate properly.
2.
Install two woodruff keys (63), rotor half (61), hub (62), and rotor half (60) on shaft (50).
3.
Install inner bearing race (59) with chamfered edge facing away from rotor half (61) until gap of 0.141 in (3.6 mm) is
between inner bearing race and shaft (50) threads.
4.
Place rotor assembly (57) in soft-jawed vise and install nut (58). Tighten nut to 110 lb-ft (149 Nm).
5.
Apply a light coating of sealing compound to shaft (50) where slip ring assembly (56) will be installed.
CAUTION
Use extreme care not to damage two terminals located on end of slip ring assembly.
6.
Install slip ring assembly (56) on shaft (50) until end of slip ring assembly is against inner bearing race (59).
7.
Install bearing (54), new seal (53), bearing retainer (52), and four screws (51).
8.
