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.
