1100 clutch centering

[bart2181]

.guys I,be tightened the clutch cover bolts only to find the decking friction plates moved a note c**k.can the plate be tapped back to centre without loosening the bolts?its probably a couple of mill out.how important is it to get it cock on,cheers guys

I see no reason to try to force it. Why don't you just loosen the bolts and recenter it?

As you probably know it has to be spot on, otherwise you will not be able to fit the transmission back on (not easily, anyway).

Doubt it without wrecking it

Just loosen the bolts centre it and retighten!

Cheers lads.the only reason I thought giving it a Ta/p is those bolts have crush washers and once tightened I presumed were no good if loosened?

I cant speak for the 1100, my 1150 doesn't have any washers holding the pressure plate on. Bolts are technically single use but.... I have done worse things than reusing single use bolts. Especially in your case where no real "wear" happened to the bolt.

They don't have crush washers, they have spring washers.

I'd just loosen them and reuse them after centering the clutch properly...

A couple of times whilst changing clutches,i have left the bolts just loose enough to hold the friction plate in as central position as possible but it will move to accomodate the gearbox input shaft when it is fitted.I then tighten each of the bolts via the starter motor gap,turning the engine with the alternator drive pulley.

I've got a u/s spare input shaft from an old gearbox - I used it to centre the clutch I've just fitted. You're welcome to borrow it (but whether it's worth the postage etc is your call )

You can use dia 4.5 mm drills to center it.

I didn't want to start a new thread but on the clutch plate topic, I have recently bought a clutch plate here in the US and the price has gone up to $170. Also I did notice that it was made is Slovakia. I am assuming that the original stock has been exhausted and Sachs pulled the equipment out of storage and moved it to Slovakia. I have heard that there was shortage of clutch plates a little while back and this story would be the most logical one. The only question is if the clutch plates are being worn out at alarming rate or killed by input shaft wear syndrome.. Either way BMW parts department is doing well.

EDIT. I am talking about 1150 clutch

+1 on this method!
I first tried to center with a kit I bought. Not one of the sticks fitted. Tried to center with what I could find in the garage, but botched it badly... Loosened the bolts and did as described above. Worked a charm. I think I first read about this in a post by Steptoe (duly credited).

+2 I just centred plate using a rule with bolts slackened off just enough to allow movement. Gearbox back on no prob. Torqued up bolts through starter motor hole.
