6) Remove Ball bearing 608LLB from the commutator end of

The space between the ball bearing and Insulation washer is so

tight that claws of bearing extractor cannot grab the ball bearing.

ball bearing, clamp the backs of the claws securely with a water

pump pliers or the like as illustrated in Fig.

Now ball bearing 608LLB can be removed by turning the handle

of No.1R269 clockwise.
