Wtd - Clutch Pressure plate SH is fine

[bstardchild]

I know I'm being very hopefull here but

Either

BMW M5 E28 Pressure plate.

or

M3 E30 Pressure plate.

Can be used - worn out - tired in fact as long as it's still in one piece and recognisable as a pressure plate I'd be happy

Basically I need one to compare and there seems to be an "M" tax on new bits - one will work just not sure which one so buying both new is gonna hurt

possibly got a used one laying around, many of them are similar to other more mundane bmw clutches. you after a centre plate or cover? some M clutch centres have a very thin friction material. come to my works if you have a part to match up, or send me an email or PM

Top chap been waiting for you to spot this post ;D

Pressre plate or cover plate

I'll take a picture of what I have now with some critical dimensions

No worries about the friction plate thickness my current one has done zillions of miles but untill it's down to the rivets it's not getting replaced ;D

[bodieanddoyle]

what I mean by thin is a very thin piece of friction material, like <2mm riveted over a much thicker piece of metal. the overall thickness is the same, just the lining is extermely thin.
cover plates are all much alike, just some have heavier springs than others. if you want, just pop over my works with the old one and we can mate it up from there
you got PM, too

Better plan (always handy keeping a spare so I don't have to remove the one from the car ;D )

You have PM back BTW

Right Pictures and a few dimensions



Hole centre to hole centre for mounting clutch pressure plate to flywheel 265mm

Much bigger and I'm into ring gear maybe 5-10mm more avaliable but not much more than that

Release bearing width 55mm



If you need any more dimensions shout ;D

e30 325i is 265mm betweend stud holes. nice heavy clutch.
e28 m535/e23 735i (also 528i/728i but less stiff) is 270 ish between studs. you have to stick with these early clutches because later engines use a recessed flywheel.
all bmw's use the same release bearing, 45mm id on the thrust face. I did measure the o/d, but its been farkin' busy this morning and have forgotten, sorry

OK I'm a tad worried about putting a 325 clutch in something with a lot more poke unless BMW over engineered them to handle much more power - unless as you say it has heavy spring pressure unlike my "Julian C" Opel item!!!

E28 M535 seems a much better bet

So I need an early version of the M535 clutch - got any old ones lying around?
