What the — ? A commutator question

Post by hull 433 » Wed Mar 18, 2026 10:09 pm

My commutator was acting up, so I took it apart and found the fiber washers had split.

In the process I noticed a notch in the brass spacer nuts. Not in the Ford parts list for the year of my car so I’m wondering what they’re for and whether they’re Ford parts at all — or just repurposed from something else during an ancient shop repair.

A picture of your commutator would help. There were many styles and I'm just using one as example. Is it like yours?
In comparing to the timer on the left, your timer would need a nut or equivalent to hold the threaded piece in place when the thumb nut was loosened or tightened . So is the mystery piece threaded?
