Title: Unknown tool
Post by: Roadwhimp on December 30, 2021, 10:08:47 AM
I was wondering if anyone could tell me what this is used for.  Maybe should be put on the Shovelhead forum but thought I'd start here.  Thanks in advance...

This is just a guess.  Back in the early 90's, General Motors was researching and building Electric Vehicles.  I believe it was a relatively new program, probably leading up to Today's Electric Vehicle craze.  I wonder if it has something to do with that.  Possibly, it is an actual part, or some type of alignment tool/jig used in the manufacturing, and/or repair.  I believe that GM moved on from the EV1 program, and moved on to EV2, EV3, etc.  Other than that, the only other thing I can come up with is something to do with Andrews Cam's, in their EV types.  Like I said...just a guess.  I have never seen one of those, but the EV1 stamp on it must be there for some reason.
Did You just recently come across that?  Or had it for a while?  I would find it interesting to know just what it is Myself.
Good Luck on the research, I'll bet somebody will know just what it's used for.

The fact that some holes are threaded & some are thru suggest to me a puller or press of some kind... like a side door puller for example.  :idunno:

Does it have bolt patterns to match either side of EVO heads?

A Trock product?

Xlfan, you may be on to something.  I was looking through a list of items that this came with.  One of the items is HD head rebuild jib for shovel and evo motors.  Never seen one before just was curious.

I think you're on to something guys. I know I've seen this tool, but I can't for the life of me remember what it does for sure. It's some form of a fixture.

I just went thru My HD, and GM specialty tools.  Both OEM, and Aftermarket.  I have quite a few pullers, alignment jigs, etc...but nothing that even comes close to looking like that.  I seem to have gotten by without one, but I would like to know what it is also.

Looks like part of a jig to service bushings/bearings or a bore on some mechanical unit. The fact it is casted then machined makes me think its defiantly not a one of.  Bob

It's for surfacing the heads. I have one. Bought it probably 30 years ago. Still using it.  :up:

It's for head machining you can clamp it to a mill table or hold it in a lathe Chuck,had mine for years,I think it came from Competition Cycles in Texas
