Dear All

Has anyone any knowlege or this....

Is the five speed clutch pressure plate just the same as the four speed version albeit with the "platen" removed...seems so?

With Platen flat faced bearing


Without Platen curved face bearing

I thought only the five speed used the 8.5" cover plate with straight fingers and that the four speed used a smaller , 8"?, cover plate with platen and the curly fingers?

I think the 5 speed has a bigger dia. pressure plate but when I looked at fitting a 5 speed box I found the dia. of a 4 speed fitted the 5 speed driven plate [just]. If you are using a 4 speed clutch arm and bearing carrier then a bit of fettling needed; the internal dia. of the carrier needs opening out and the finger ends of the arm need a bit of filing.

The standard 5 speed pressure plate suited a maximum 8.5 inches clutch plate and a 8.5 inch clutch plate was fitted. The splines on the 5 speed gear box are different from the 4 speed for the clutch plate

The standard 4 speed pressure plate also suited a maximum 8.5 inches clutch plate but a 8 inch plate was fitted as standard. It can be replaced with a suitable 8.5 inch pressure plate.

There are detail differences in the 5 speed pressure plate in terms of the thrust bearing locating mount height and style but otherwise they are fundamentally the same.

John.

I believe the guy who I bought my Plus 2 off has a new pressure plate for a 5 speed box.

I think he's looking for around ?35 for it and based in South Yorkshire. He's on holiday until the weekend, but if you need one I can contact him.

One can use either 8" or 8 1/2" friction plate and 8" or * 1/2" pressure plate on 4 speed Twincs..

Agreed...

Don't need a pressure plate yet ( especially if removing the platen gives me one )

Just trying to get rid of a nasty rattle ( only at tickover in neutral without the clurch depressed ) coming from the clutch cover,which I think is the loose platen,

Next step to adapt the curved-face bearing to the carrier ( vice-versa )
