This part is labeled as a Cam Spacer. Question is Do I need it, and if so where does it go? It is the exact diameter as the timing gear end of the cam. I checked the 84 Service Manual, but don't see mention of this.
There is a plate with two bolt holes that is located behind the cam gear. It's been a while but I believe it's like a crush spacer inside the thrust plate.

No.
retainer/trust plate Does Not use anything to keep clearance etc. Gear is press on the cam w/ a bit of play so retainer moves freely. Gear teeth won't allow play when engine is running.
I've never seen the part before. See my Cave, Cam Gears

Zeak, yes, that is the part. This is in the Pontiac engine build kit for the SD 4. Puddlejumper, could you Post a picture from the cd of where this part goes?
This pic has it as #145 http://www.google.ca/imgres...kso4lM%3A&zoom=1&doc id=0S7rJYCttW0OyM&itg=1&hl=en&ei=vVOkVOCkBovkoATUtYC4DA&tbm=isch&ved=0CFEQMygrMCs&iact=rc&uact=3&dur=1200&page=2&start=32&ndsp=41
The spacer goes between the cam gear and camshaft. Measure the thickness of the thrust plate and the spacer. If the spacer is .005" thicker than the thrust plate, you have your answer.
I used a press to install the cam gear on my '84. If you press the gear on too far, you will lock up the thrust plate. I used the spacer for that reason.
I have not measured it,but take another look at the pictures. This thing is pretty thick. Perhaps 1/8th of an inch. Certainly more than these tiny measurements that would be done with a feeler Guage. Still don't understand the use of this part.
bump: No body had their Duke cam (or timing gear) out recently to confirm if this is the spacer being used or not????
What I really dont understand is why the one side of this spacer is beveled. One side is square/flat (I assume this side would face the block) and the other side is beveled.
