Title: which is the flywheel side of a clutch friction palte?
Post by: terry paget on 30 January 2014, 19:29:39

OE03EWW 3.2 petrol manual saloon
LUK clutch kit arrived today. I was expecting the friction plate to be labelled flywheel side, but it is not. How can I tell which is the flywheel side?

Anything stamped on it at all :-\

Getreiben Seite is gearbox side if that helps :y

Thank you. Getriebeseite it does say. I must brush up my German.

If you look at the friction plate you should see a raised section on one side, this usually has the spring mechanism on it which works with the pressure plate to engage/disengage the friction plate from the flywheel.  The side with the raised section would be the gearbox side. I will try and find a picture of a typical clutch friction plate.

Here you go.

The problem is that the Omega does not have 'cush' springs due to the presence of a dual mass flywheel :y

So the friction plate looks like this:

Thanks. There are no springs in my friction plate, to my surprise. I imagine they were some sort of shock absorbing system. Perhaps the dual mass flywheel does a similar job.

Thanks Marks, it is true that you (in this case me  :) ) learn something new every day ;D

Even more relevant in my case is  'Old age doesn't come alone' ;D ;D

Thats right, the dual mass flywheel (DMF) is a two part item, one part engine driven, the second has the pressure plate bolted on it. The two are coupled by a set of large springs inside the DMF.  :y

How is the DMF superior to the cush spring clutch plate system? I have read of DMF failure. At least in the cush plate clutch you changed friction surfaces and cush system together.

Quite simply its smoother, you have two rotating sprung masses and this dampens engine pulses and flattens them out. The cush springs did nothing more than dampen gear changes (and the springs on them did also fail sometimes)

On the likes of the Omega, DMF's are very reliable, modern high power diesel engines with high torque pulses give them a battering (plus racing starts and hard changes knock the springs out).

Thank you Mark. As Ever Ready observed, we learn a lot on this forum.
