I have replaced the rear main seal while I was to do a clutch spline lube etc.

I have looked at Chris Harris's UTube videos and referred to the Clymer manual.  The manual says to apply lube to the outer rim of the diaphragm spring as well as the raised points in the centre.  Chris Harris does not mention this at all.

Other than the pins of the housing cover does anybody apply any lubricant to other parts of the clutch assembly?

P.S.  Man the rear main seal is a bugger to get in!

BMW rear main seal is the one to use and don't drive it all the way in. It should be proud by the thickness of a fingernail. Oil before installing.

yes indeed mate
the hinge pins - bearings - bushes on the clutch arm as it attaches to the hinge pin on the  lower part of the gearbox housing

many have installed a grease nipple to the arm about the centre of the mechanism to lubricate it

at times especially after a good ride ….in rain soaked roads .. I get a very hard to use clutch action but after lubricating the arm the action is very light .

recently I replaced the bearings in the clutch arm with bushes as the bearings had eaten into the pivot bolt of the pivot of the arm making it realy hard to use ...and I recon a cause for many clutch cables breaking with the added load of rotten bearings …(there are some good posts about clutch hand lever binding with the cable in here ...look them up ..as its a quite common issue )

the area im talking about

I don't lube the rim of the diaphragm spring but I do lube the ring that it rides on which is more or less the same thing.

If you lube the clutch arm then be careful removing the circlip on the end of the pivot rod or buy a spare one at the dealer ahead of time. It's one of those small parts that likes to fly across the garage and get lost.

I am to clean and relube the bearings and pivot pin on the clutch release arm.

Seems no one lubes the diaphragm spring other than on the ring in the clutch housing.

You need to lube the part that touch the pressure plate there are 10 or 12 small nodes.

Thanks Rick G.  That agrees with Clymer manual, but, they also indicate for the diaphragm spring ".....to the perimeter and the raised portions.....where they make contact with the pressure plate".

The raised portions they show in the diagram are the spring steel "clips" that connect the centre portion to the outside.  I am guessing this is just to lubricate the spring steel "clips" rather than as a contact point.  If this was the case you'd think they would lubricate all the points where the outer disc contacts the inner disc.

I bet this is common knowledge once you've done it, but, certainly isn't too clear.

By lubricating one the other is lubricated upon contact. You don't need much just a smear with your finger.
