Re: Thrust bearing noise..... or is it?

Back again.
Found the old small trolley jack and jacked the car up in stages like the old days.
Adjusted the clutch so there was a 2mm gap at the lever. Without even dropping the car I could tell the bite was an inch or two off the floor. There was a lot of 'free push down' on the pedal before the lever even started to push the clutch.
So.
I adjusted it up to the end of the rod.
So.
The clutch now disengages further up.
That means the slave is constantly under pressure even with no foot on the clutch.
That also means that either the slave, the rod or the master cylinder are not correct for the car? (I reckon).
Pretty sure the slave is correct but can't remember if the master cylinder maybe/could have been changed for something else in the 100 years I've owned it (I did replace the seals last year no problem, and I do remember years ago thinking I'd like to make an adjustable longer master cylinder rod (to pedal) to take up the slack.
Anyway - bites in a nice place. At the moment.
The noisey thrust bearing is still there but not so pronounced as the other day (I think). I could only drive about. 50feet because a tractor was in the way so couldn't say whether it'll still be there during a drive.
As Rohan said I need to drive and see if the pedal bites in a different place as it wears in, then readjust.
I do also agree that pulling the engine again is a last resort.
In theory, it should slip badly with the rod adjusted so far out - we'll see.
I need to drive it.
Thanks again all.
