INSPECTION - CONTINUED

Check for short circuits in armature (13) using a growler and steel strip.

Rotate armature (13) in growler.

Hold steel strip (e.g., hacksaw blade) across armature slots as armature rotates. Steel strip will vibrate as slot between

shorted bars passes under steel strip.

10.

If short circuit is detected, check for build up of copper dust or other conductive material between commutator bars.

Clean out copper dust and check again for short circuits. If commutator bars are shorted, replace armature (13).

11.

Check armature for grounds or open circuits.

12.

Set multimeter to ohms, on highest scale. Check for grounds by measuring resistance between commutator and one

armature bar.

13.

Switch multimeter to lowest scale.

14.

Place multimeter leads against two adjacent commutator bars and observe multimeter. Multimeter needle should swing

to zero and remain.

15.

Repeat check for all commutator bars by moving one multimeter lead at a time. There must be continuity between each

pair of bars. If there is no continuity between one or more pairs of bars, replace armature (13).

ASSEMBLY

If removed, install bushing (40) in drive housing (22).

Install bearing (39) on driveshaft (30).

Position shaft support (31) and drive clutch assembly

(32) on drive shaft (30).

WARNING

Use care when removing snap and retaining

rings. Snap and retaining rings are under spring

tension and can act as projectiles when released

and could cause severe eye injury.

Install pinion stop (37) and new retaining ring (38) on

drive shaft (30). Retaining ring may have to be forced

over driveshaft using a block of wood.

shaft (30).

Install shifter fork (27), drive clutch assembly (32), shaft support (31), and driveshaft (30) as an assembly in drive hous-

ing (22).
