F1 racing chromoly e36 m3 flywheel doesnt fit on my 24v

[graphikg]

I tried to fit the flywheel on my car but not only is it about an inch thicker than the m20 lightened flywheel I had on there, but it doesnt fit. Of the 8 threaded holes on the block, one has an alighnment boundary where you can set the flywheel to start bolting it, but it seems too large for the holes on my flywheel.

What do I do? Should I shave one of the holes on my flywheel a little larger to fit it?

Maybe they sent you the incorrect item? I wouldn't start drilling or cutting anything. You paid good money for a part and it should fit contact the seller and figure out what's going on.

Disregard my earlier post, I read your other thread and now just realized youre running a getrag 260 and not a zf. If and when you do get it properly installed, please post a review of the quality and feel of the new setup. I have a s50 with a zf and I'm debating whether to getths lightweight f1 flywheel with the f1 stage 3 clutch or the own sachs. Than in advance and sorry I couldn't be of any help. -David

I will call them and see what they say. They already have to send me the alignment tool for the getrag 260 pilot bearing since it is different from the zf one. I think the flywheel fits, it is just that one of the holes has that border around it which stops the flywheel from setting itself in place.

The alignment dowel is there to always make sure the flywheel goes on in one way... If you drill some out of the flywheel you may have check the balance on it. Let me think about this.

Dont drill it. Have them take it back and send you a new one.

e46s54dr - Im running the F1 Racing Lightweight Flywheel and 6 puck unsprung clutch in my car. I like it. It's holding up quite well. My buddy in his m3 is running the same one and has driven HIS car more than I have and the clutch hasn't come apart. Make sure you install the clutch disc the correct way though.

Evil Twin... So the holes from your flywheel from f1 racing did clear the alignment dowel on the block? Or did your block just not have an alignment dowel?

I am going to give them a call today. And which way is the right way for the clutch disk --- I notice that it needs a specific orientation.

NVM figured it out. I just used a pair of pliers to pull out the dowel. Bent it off quite easily, and my flywheel is already bolted on to 77ft lbs just fine.

Great! That's what I was hoping to hear. The price for the set is unbeatable and it'd be great to have if I decide to boost the engine a little later down the line. I appreciate your response and review.

Oh no, you really shouldn't have done that.
Are you 100% sure that one of the holes in the fly wasn't larger than the others? It should have been, and without the dowel the flywheel isn't located on the back of the crank properly.

Also, loctite those bolts into the crank.

Actually, when I contacted gripforce (the people I got the clutch kit from on ebay - good cust support BTW), the guy said that I should remove the dowel if I could because there isn't one hole that is larger on the flywheel. He said that he has never heard of anyone contacting gripforce about that dowel question, whcih is weird to me because I am sure someone has run into the same issue.

The gripforce guy said that there is no modification needed on their kits, and the flywheel to the crank should be fine after removing the dowel.

The way I tightened the bolts were by first handtightening them in the "1-7-3-9-5-11-6-12" pattern, then turning them about a 1/4 way with a socket in the same pattern, then torqueing them to 77 ft lbs with blue loctite to finish it off in the same pattern.

SO I think it shouldve been done correctly.

The alignment dowel position is different on an s52 than it is on an s50, they probably sent you an s52 flywheel or vice versa depending on what you are running (s50 iirc?)

Removing the alignment dowel is not the right way to do it.

^^^^ AWWWW... Well thats what I did already. I actually have an M50 block bored to 3.2l - so it is an M50 with an alignment dowel on the crank.

There was literally no other way of doing it. Either drill one of the holes a little more open (which gripforce did not recommend), or pull the dowel.

I also noticed on the m20 flywheel that I pulled from the motor, that one of the the holes was larger than the other 7. There was also a yellow mark indicating which one was the larger hole - this makes me think that someone did enlarge it.

I really dont see any repercussion for removing the dowel... it just helps hold the flywheel in place as you start to bolt on the flywheel.

You'll be fine, it's really just an alignment pin. It isn't the proper way to do but with the right torque and loctite, you should be fine. For your 3.2L build, did you use the s52/m52 crank to stroke it or did you just simply bore out the cylinders with a stock m50 crank?
