When removing Ball bearing 6001DDW, separate Retaining ring WR12 first from Armature shaft.
Then remove Ball bearing 6001DDW together with Sleeve 12 at a time using 1R269.
See illustrated below.
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
ring WR12 using common retaining ring pliers or 1R003 with 1R212.
