6. Remove the auto-tensioner (see page 4-32).
7. Clamp the auto-tensioner (A) by using two 8 mmbolts (B) and a vise (C) as shown. Do not clamp the
auto-tensioner itself.
8. Set the torque wrench (D) on the pulley bolt, and align it as shown.
9. Align the indicator’s pointer (E) on the tensioner base with center mark (F) on the tensioner arm by
using the torque wrench, and measure the torque.
If the torque value is out of specification, replace
the auto-tensioner.
NOTE: If the indicator exceeds the center mark,
recheck the torque. 1. Remove the drive belt (see page 4-31).
2. Remove the idler pulley base.
3. Remove the pulley bolt (A), then remove the

7. Remove the four through bolts, then remove the
rear housing assembly (A), and washer (B).
8. If you are not replacing the front bearing, go to step 13. Remove the rotor from the drive-end
housing. 9. Inspect the rotor shaft for scoring, and inspect the
bearing journal surface in the drive-end housing for
seizure marks.
 If the rotor is damaged, replace the rotor assembly.
 If the rotor is OK, go to step 10.
10. Remove the front bearing retainer.
11. Drive out the front bearing with a brass drift and a hammer.

12. Install a new front bearing in the drive-end housing
with a hammer, the driver, and the attachment,
42x47mm.
13. Measure the length of both brushes (A) with a vernier caliper (B).
 If either brush is shorter than the service limit, replace the brush holder assembly.
 If brush length is OK, go to step 14. 14. Check for continuity between the slip rings (A).
 If there is continuity, go to step 15.
 If there is no continuity, replace the rotorassembly.
15. Check for continuity between each slip ring and the rotor (B) and the rotor shaft (C).
 If there is no continuity, replace the rear housing assembly, and go to step 16.
 If there is continuity, replace the rotor assembly.
