Clutch fun

[Topcat502]

Apologies if already answered here as I can't find in the search I've done...
So, I'm well into a strip down to sort said clutch and a few other bits...
During the strip down, some of the upper rear frame bolts snapped, despite heat
and penetrating oil
(another gsa garage adventure starts)
The rear input shaft seal was leaking so have replaced that, what I've noticed
in the BMW rom manual, it doesn't mention the clutch push rod. (again might be me not checking the right file area)
Should the push rod be installed lubed? Haynes said to do so. Just seemed a bit "grabby" where it enters the engine..
(holding push rod free hand into engine)
I presume the felt seal should also remain dry??
Have attached a couple of pics to help paint a few more words.
Did I also read somewhere that replacing exhaust stud nuts with brass ones?? (for further strip down of the above).
Despite how fed up I am right now, I still love this bike
Cheers All any further pointers certainly most welcome.....

Don't quote me on this as it is over a year since I did mine and I didn't take notes, but I'm pretty sure the bmw technician I spoke to before I did the job suggested moly grease on tips of pushrod and on exterior of felt seal. Small amounts

I though my clutch had gone... then I went on a long 100 mile each way ride and its not slipped since !!!

keep meaning to take the starter off and squirt some brake cleaner about and get any dust / liquid gunk out that's gone in there from bleeding the ABS that's died twice and the buckets of soapy water I threw there to wash off the paint destroying muck that is brake fluid…

I didn't realise that BWM and their brain dead design team built the breather at the top so any oil, lube, crap, rain water and bubble bath (when you wash the bike) gets to flow straight on to the clutch and has no way to drain out !!! Only saw the half moon trash the clutch feature after looking at a bike with the gearbox out...

the felt bit is to stop it rattling,

The push rod rotates all the time the engine turns at the same RPM.

A very very small amount of grease on the end of the push rod that engages with the diaphragm spring would not do any harm. To much and it will just fly off, which you do not want. But really it’s not necessary as there is no rotational movement between the push rod and the clutch diaphragm spring.

The felt is there to mop up any oil which may track from either a leaking gearbox seal or clutch slave cylinder. I always leave them dry so they can do their job.

The other end of the push rod engages in the thrust bearing on the slave cylinder piston, so no need to lubricate, but no harm if you do.

That’s the way I do it.

I scared myself silly in Ireland while touring when the clutch showed signs of slipping under load, only to realise the handguard had a knock and was fouling the lever returning to the fully out position.
