Well at least I know I’m not going crazy then that it happened to someone else!!!

That’s why o was wondered if it was mounted backwards? That’s the way it came with the clutch. On the other side is flanged. I was wondering if the flange side should face away from the block? See if I can take a picture of it.

I just counted the teeth in my picture again and it is 142 teeth so it’s the right size flywheel. Maybe the bell housing want cut right?

Yes the flywheel-clutch and bellhousing all came from Safir. I’ll have to count it again and make sure I want off a tooth.

In case anyone is keeping track I’m somewhere in the neighborhood of 60-70 attempts of mating and unmating these two with zero success and just a much worse lower back. So I took it all apart and started with basics - assembly one piece of the puzzle at a time until I figure out what the...

Well Christmas has come and gone and I got my bushing. Of course I could ]not find the correct size so I needed to get one cut down a little to size. Put everything back together today hoping for a Christmas miracle but Murphy’s law is strong at my house. Same 1/4” gap!!! Had to walk away as...

I finally got around to testing the zf with just the bellhousing and it easily fits. Just waiting on a bushing and will reinstall it all back together.

Thanks I found some old posts showing the M1 has a 12mm input.

That’s curious. I did search some old threads and saw where they were used in M1s and had longer input shafts. My ZF was for a Pantera as I had to get Ron McCall to flip it and had him tear it apart while he was at it to go over everything. I’m curious now what the input shaft length should...

Thanks! Ordered a new Timken bearing and will replace it. I’m not sure why others on here are stating it should easily slide on and off? My mistake was not seating it all the way into the crank.

Okay I pulled everything apart again. I pulled the pilot bearing (been so long I thought it was a bushing in there!). The bearing is Koyo 6003RS. It is spec’d at 17mm ID. The input shaft on the ZF is a;so 17mm (actually measurements I got on it were anywhere from 16.93 - 17mm. I contacted...

The snout is going through the bushing but something is ‘hitting’ on the last 1/4”. I assume it must be the splines making contact and that if I sink the bushing deeper in the crank it will fit fine. I’ll measure it when I separate to know for sure.

Yes I have the backplate in.

The tolerances are very close on the bushing. Even when I’ve had to pull it apart it’s really in there where I need a pry bar to separate the engine and trans axle. I tried some scotch brite in the input shaft thinking it might have some residue on it or something but it’s clean.

That could actually be the problem. It would explain the 1/4”. I’ll pull it apart and let you know.

BTW I appreciate the suggestions Lee. Sometimes these chats comes off wrong. I’ll gladly take any hints, suggestions or questions in case I missed something. I’m going to try some more things tomorrow and hope it slides in!!!

I took the shims out, tried the bushing on the zf shaft when I got it and it ‘fit’ (just started it as I didn’t want to have to pull or press it off. Also the bushing was flush/ just past but not bottomed out in the crank.

I’m having problems mating my zf with my engine. I’ve never had and engine/trans so hard to mate up. I have a zf-2 with a safir bell housing with McLeod dual clutch package. I spoke to Bob Wood before ordering and gave him all the proper information for my zf. I set the distance for the...

I have this tool set for my Cobra (and soon I’ll be using it for my GT40) and have to say it is a very solid kit. I like to torque my wheels on and then give it a whack with a lead hammer and safety wire it. What I find this kit most useful for is removing the spinner. It’s a lot easier to...

That’s the same block and heads I have from Prestige. I should have sent the the valve covers when I was getting the engine built! I tried dry fitting them and didn’t think there was any clearance issues but maybe I was wrong.
