ASSEMBLING

Fig. 29

When inserting Armature into Inner housing complete,

do not fail to pass Armature through Yoke unit in advance.

Note: Yoke unit is not directional when assembled with Armature.

Without enough care, Ball bearing 6001DDW on the drive-end of Armature may often be incompletely seated in the bearing room of Inner housing complete. Therefore, fit Ball bearing 6001DDW completely into

the bearing room in Inner housing complete while carefully turning Armature by hand to engage the gear of Armature shaft with Spiral bevel gear 26 in Inner housing complete. Then fix Ball bearing 6001DDW with Bearing retainer and two M4x12 Hex socket head bolts.

Note: Be sure to apply adhesive (ThreeBond 1321B/ 1342 or Loctite 242) to the threads when reusing M4x12 Hex socket head bolts removed from the machine because they are threadlocking bolts.
