Poor Generator Practice

[Tom Wesenberg]

Here's another example of extreme commutator cutting. Notice the small diameter of the commutator and the large gap between the brush holder and commutator. Even though the brush may look full length the spring is almost hitting it's stop, so the brushes will have a short service life. The brush holder also appears to be off center, which makes the problem worse. This generator is on ebay right now.

A properly restored or repaired generator doesn't mean the commutator has to be cut. They only need to be cut if they are rough or have a burned segment, or have runout.
