(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)
