1978 MGB noisy clutch release bearing

[ATE399J]

All,

About 6 months ago the clutch died and l had it replaced, the garage that did the work said that although the clutch was warn the release bearing was in a terrible state which was why it had been making so much noise ( to be honest l hadn't noticed ).

Now, six months down the line and l can definitely hear the bearing ( noise in neutral, clutch down and noise stops). So, my question is:- is there some sort of adjustment that would solve this problem? Has the car got something wrong in the actuation mechanism (wrong slave push rod or something)? The garage didn't say they found anything wrong - but they probably weren't looking.

Ideas?

P.

Did they offer to replace it whilst it was all apart?

If not, it is my opinion that they should have. (It is easy for me to say that on the interweb )

If you said you'd wait until it broke it is going to be an expensive repair to a few quid's worth of bearing



If it is the carbon type the noise you are suffering now is likely to be the cast iron carrier rubbing against the clutch after all the carbon has wafted away with the usual clutch dust

It was replaced when they did the clutch so it's done less than 5000 miles.

I could well be wrong but the first thing that comes to my mind is piss poor quality of new parts perhaps combined with poor or not best practice by the driver of operating the clutch

have a look at this for more detail - How to Not Destroy Your Clutch the Easy Way - https://www.youtube.com/watch?v=d173K60GSU8&li...

also you do not dip the clutch or lift off the accelerator pedal when engaging or disengaging the overdrive, it needs load to operate properly

I have been driving since 1978 and this is only the second time that l've had a clutch wear out. I am used to overdrives - don't dip the clutch, just flick the switch.

I would certainly hope the garage that did the work didn't leave the engine "hanging" on the input shaft and they charged me for a new bearing (l did know that it's a carbon slip ring sort of set up rather than a classic bearing and have heard that fitting one of these as an "up grade" isn't necessarily a good plan) so l guess they fitted one.

I'll just see how it goes for the next couple of months, if it gets louder l suppose l can always turn the radio up.

sorry the comments were made as general, I wasn't trying to besmirch your manhood

it's still worth looking at that video for background info

I keep my "manhood" in check at all times!!
I just have some suspicions about the way it was assembled before l got it. Wrong length clutch actuation rods etc. wrong gearbox even, l have even heard of engines being rebuilt with the wrong crankshaft!!
I will look at the video

Thanks for the advice guys, l'll assume it's the input bearing and turn the radio up!!
