In the process of removing and rebuilding my wiper motor, I broke the post on top of the motor gear. The one that the circlip attaches to... Anyway, I think I just need to replace the gear, but I can't find the part on any of the parts websites. Victoria British has a gear for a TR6 wiper motor that looks similar. Any idea if this part will cross over and replace the one on my TR3A?
 
Moss also has a gear for a TR4, not sure if that would fit either. I'm in a 1961. This is the motor I have Screen Shot 2018-07-22 at 7.41.32 PM.png
 
Josh,

Your motor could be a DR2 or a DR3A type; it should be stamped into the flat cover over the gear part that the dome sticks through. The DR3A driving wheel was slightly bigger diameter than the DR2, so not interchangeable. Also, the sweep of the arms should be stamped into the metal part of the gear, something like 115, 130 or 125. Not sure what the TR3 used.

Quite sure all the TR3As used DR2.
