Great idea, Bill

<= div>I thought of that also.

I kinda wanted to let t= he prsu remain virgin until I mounted it on the engine after rebuild. <= /div>

What I did today was using a caliper made measureme= nts of the front disk, shaft,outside measurements of the bolt circle diamete= r, distance between the close bolts, distance between far bolts (all outside= of head to outside of head) and the diameter of a ale bolt head
<= br>
With these measurements I should be able to recreate the bolt p= attern successfully. I was just hoping somebody else had done it before me (= I hate reinventing the wheel-- or prop

When I do t= he calcs make the piece and fit it , I will post it. Probably some time this= winter when I tear into the engine

Thanks for your= help

Thanks, Bill

 

Almost

 

In Tracy's prsu, the forward oil seal is in a=20 circular aluminum piece which is attached to the prsu by several Allen bolts= =20 which are arranged in groups of two. What I was looking for is the diameter o= f=20 the bolt circle and the spacing of those bolts=20

 

My bracket will be a flat steel plate affixed to the=20= front of this plate using 3 of the bolts. The brush/rpm sensor will be conne= cted=20 through an ear on this plate

I have already designed the mounting=20 plate

 

All I really need is the spacing of the bolts so I ca= n=20 make the fixture before I disassemble the=20 prsu
