Utah State snowmobile motor

I got a call from Utah State to see if I could offer any options to extend their range. They are getting 3 miles at 35 MPH. I offered to trim some fat and create an extra pair of terminals. This will allow them to use the motor with the fields wired for series / parallel or series. I forgot the camera on the day I finished it but I was able to get a few pics worth looking at. The most immportant are the brush ring, and armature pics. It shows the lack of proper brush seating and what happens to the armature.

The armature comm. raised some flags. The edge showed signs of being over-burdoned.

Here is another shot of the comm. You can see the two different patinas where the front and back brushes ride. Although the pic doesn't show it the comm was quiet purple close to the riser.

Here is the reason the comm was getting upset. You can see that the brushes are barely seated. The hard hit area on the comm was actually the better seated brushes as it took most of the current.

This is an OEM field coil set and the bobbins they use to insulate them from the housing and pole shoes.

On top of the unseated brushes I found two mount threads stripped out. I informed them to tell the gorilla to ease up a bit : )

Getting back to the fields, here is a closer shot of the bobbin after I gutted it like a fish and removed it.

This is why I like fiberglass wrap, ohhhhhhh. I added a 10 mil Nomex arimid paper wrap around between the coil and the pole shoe for added insulation. Sorry but I had no camera to show these dipped and installed : (

Thought I'd catch an action shot as I turned the comm end plate.
