Note: Retaining ring WR12 fits into a groove on Armature shaft. The groove is too small to have enough room to insert
tips of common retaining ring pliers.
Therefore, move the clearance of WR12 to outside of the groove using 1R004 or 1R291, then remove Retaining

When inserting Armature to Inner housing complete,
do not fail to pass Armature through Yoke unit in advance.
Note: Yoke unit can be independent from the directional of
front end and rear end.
Ball bearing 6001DDW on Armature gear shaft side may be incompletely
fit into the bearing room in Inner housing complete without full attention.
Therefore, turn Armature by hand to engage the gear shaft with Spiral
bevel gear 26 in Inner housing complete and fit Ball bearing 6001DDW
completely into the bearing room in Inner housing complete. After that,
fix Ball bearing 6001DDW with Bearing retainer and two M4x12 Hex

Note: Be sure to apply adhesive (ThreeBond 1321B/1342 or Loctite 242)
to the threads when fastening the reused M4x12 Hex socket head bolts
because their bolts are threadlocker type.
Make sure that the following parts are set in place before assembly of Housing R to Housing L.
