Thanks, Bill

Almost

In Tracy's prsu, the forward oil seal is in a circular aluminum piece which is attached to the prsu by several Allen bolts which are arranged in groups of two. What I was looking for is the diameter of the bolt circle and the spacing of those bolts

My bracket will be a flat steel plate affixed to the front of this plate using 3 of the bolts. The brush/rpm sensor will be connected through an ear on this plate

Thanks,

Rich

Rich,

If I understand what you are asking, I think Tracy’s PSRU has a SAE 2 flange. The dimensions are in this gif.

Thanks bobby,

I have already designed the mounting plate

All I really need is the spacing of the bolts so I can make the fixture before I disassemble the prsu

Greetings gentle people,

Does any body have a diagram (and measurements) for the bolt pattern of the front plate of Tracy's rd1-c prsu

I want to make a bracket to hold a ivo brush assembly.

Thanks in advance
