Morris Minor Owners Club

Is the 'thrust bearing' for a clutch on a 1098 Traveller the same thing as a 'motion shaft bearing'? I've been looking for a thrust bearing online to see how much they cost but can't see anything listed by that name. Please does anyone know what other names it might be called (other than Alfred)?
Fab

this is it, called a clutch release/thrust bearing


Thanks go to ESM for the picture

You might find difficulty getting just the bearing, Birmingham Morris Minor Centre however sell them separately. (just bought one recently!)

Fab,

If you brought a 'clutch kit' you should have a thrust/release bearing in it.

A clutch kit used to contain:

Clutch plate, pressure plate & release bearing.

But it is a few years since I needed to buy one

As someone said (Cam?) changing the clutch on a moggie is a simple job - well compared to modern FWD cars. Which reminds me I did buy one (clutch kit) about 2 years ago and it did have a release bearing included. Some kind of Renault FWD and a really .....pain to change - remove all front suspension, drop sub frame, find hidden roll pin, etc. etc. Give me a RWD car any time - and they handle so much better

Does anyone do a proper roller bearing type release - rather than the nasty old carbon item ?

A motion shaft bearing is a completely different animal. A clutch thrust bearing is pretty universally known and I would say that most suppliers would be able to sell you one even if you had to ask over the phone as opposed to on-line. I too have had them from Birmingham in the past.

BMC, I think it's best that fablovely just gets the standard replacement item to avoid confusion/complications but yes, Birmingham to a roller bearing type to go with their uprated diaphragm clutch cover but they are not brilliant and I'm on my second one which squeals it's head off!

Thanks. I haven't bought one yet. I got a quote from a clutch clinic and their price includes the clutch. I'll bell them tomorrow and see if the clutch they put in will include the thrust bearing

It.'s 99.9% certain that it will - I've never found a replacement clutch kit for any vehicle that didn't, and the rule of thumb has ALWAYS been to change it when the clutch is done whether or not it looks OK

Cam - I just wondered - because the old carbon thingy is the reason you MUST NOT sit with foot on the clutch in a Minor - and fab had said earlier that the carbon thrust in her car was worn away to nothing.

Is it a straight swap between the carbon TB and the roller bearing TB?

I used to run a ball bearing relase bearing in my racer , it came I believe from Bath Morry centre , and was a direct replacement.

Eek! I wasn't aware that I'd been doing that...my clutch pedal was a bit
extra giving (I had to put my foot down almost to the floor to change gear). Anyway, I'll be extra careful when I get the clutch replaced.

You might not have been! everytime you use the clutch a tiny amount of the carbon will be scraped off, and think what London traffic is like....

Yes, years ago I got into the habit of not sitting with my foot on the clutch after having a few cars with a non-existant clutch and not wanting to wear the last thou of meat off it! It's a good habit to get into and has served me well after buying a Rover 216S with a slipping clutch and driving it for another 4 1/2 years without changing it.

A lot of Minors that I come across seem to have the clutch bite point virtually at floor level and it's simply because it's not adjusted correctly. It's a pet hate of mine and I always re-adjust as it bugs me.

The roller bearing fits into the throw arm the same as the carbon bearing but it's contact surface is not flat to match the corresponding piece on the clutch cover it is curved to match a 'fingered' diaphragm.

See the rightmost one in this picture:

A pet hate of mine is when bite is much off floor level

I like a nice low bite point, although not quite so low that you're compressing carpet to fully disengage!

In all my cars - I never sit with foot on clutch. Horrified to find my daughter was taught by driving school that it is quite correct to sit with car in gear and foot on clutch. Aghhh. Never mind the release bearing - think of the engine thrust bearings !!
Also ok apparently to 'zippp' the handbrake - the instructor noted that my daughter did NOT do this (my instruction) and told her she MUST do it - to make sure the examiner realised she had set the handbrake - and anyway " it doesn't do any harm " !!! Dear oh dear .

Every time I hear that this sort of lunacy is being taught now, I'm told that it IS correct, but I can't believe it in this case. Anyone know different, and if it is true, why?

It IS the way it's taught - along with slowing down/stopping in 4th gear at traffic lights, no 'going down through the gears'. Seems brakes are for slowing and gears are for accelerating. My daughter did pass - and she does not now zipppp the handbrake!

The gear thing is one of the bits of idiocy I was thinking of. The sitting in gear with foot on clutch seems to me to be every bit as daft, for at least two reasons. I'm intrigued as to what the reason for saying it is, and whether it's as half witted as the gear/brakes one.

Yes, I was horrified to find that both my son and daughter were being taught
to sit at the lights with the car in gear and the clutch depressed!! I soon put
a stop to that and they both passed first time. The standard release bearing
will last as long as the clutch if you do not sit with it depressed when you
shouldn't! The only noisy release bearings I haveever had have always been
the ballrace type.
