The clearance between Ball bearing 608DDW and Drum is too small to insert
the jaws of 1R269.
Therefore, sharpen the jaws.
Fig. 14
Insert the jaws of 1R269 into the clearance Ball bearing 608DDW and Drum,
and fix the jaws of 1R269 in Vise.
Remove Ball bearing 608DDW from Drum.

Take the disassembling step in reverse.
Note: When assembling V-pulley 4-37 to Drum using Wrench 13, it is not necessary to tighten the V-pulley
to very high torque.
Reaction torque caused by stopping the rotation prevents V-pulley 4-37 from being loose.
