Fig. 7

Fig. 8

8. Remove Baffle plate. 9. Remove Yoke unit by tapping Main frame

complete with Plastic hammer.

While aligning Notch of Bracket side to Pilot Rib, insert Yoke unit into Mainframe

complete to fit Notch of Commutator side to the accepting Rib which is molded in

Main frame complete on the Commutator side.

(2) Assemble Armature to Bracket, and set V-pulley 4-24L to Armature by taking the disassembling

step in reverse. (Refer to Fig. 6)

Note in Assembling:

1. Tighten V-pulley 4-24L to Armature shaft by turning it counterclockwise.

2. It is not necessary to tighten V-pulley 4-24L to very high torque.

Reaction torque caused by stopping the rotation prevents V-pulley 4-24L from being loose.

(3) further assemble by taking the disassembling step in reverse. (Refer to Figs. 5, 3 and 2)
