If anyone gets stuck and for some reason needs a new clutch return spring, a mop bucket spring works perfectly :) found this out at a service station today.

I don't use one- so my clutch is now self-adjusting, like 99.9% of more modern cars, including Rover Mini. 8)

I must admit I religiously ran springs for years ... until persuaded by Kev. Several years on it seems to be going fine...

Cheers, Ian

It does work without the spring but I can't help thinking it is suppose to be there !? Anyway, my mop bucket spring aka MBS, is currently working a treat!

Any ideas on why they designed it to have a spring on the slave if it doesn't need it? Any premature throw out bearing wear? Do you still run a 20thou gap on the arm? I might try it without as well - I have never liked the original setup

Any ideas on why they designed it to have a spring on the slave if it doesn't need it? Most small cars back then had adjustments on the clutch. 1st one that didn't I think was the Hillman Imp. When Rover fitted the Verto clutch to the Mini in 1980? they did away with this adjustment. Note their slave cylinder is almost the same, except for mounting.

Any premature throw out bearing wear? Not so far, the only load on the bearing is the ounce or two now provided by the tiny spring inside the slave cylinder.

Do you still run a 20thou gap on the arm? No, you wind the adjusting screw in so it's well away from the arm. Standard clutches that run no gap here DO overload the release bearing (and the engine's thrust washers).

Thanks Doc.
I noticed that you originally said it would wear out the standard ball bearing type from an old post I was reading. That was 10 years ago so obviously your thoughts changed. I haven't checked if mine is a carbon or ball bearing.

It is a ball bearing, I am running the current design RHP one, not the early (better) flat one which is pretty well NLA now.

Won't she who must be obeyed crack it when she can't squeeze the dregs from the mop? I suppose you could put a spare hold-down bungy rubber in its place and say someone on Ausmini told you it works better than the dodgy old spring on the mop bucket so, in her best interests, you've effected the swapover. :shock:

I just pulled a spring off a ironing board that could do that job as well or a carby spring too might chuck it in the tool bag I carry

Yeah I have a flat one, I'll fit it if/when this RHP 7W5-8 one gives up the ghost. The diaphragm is an orange dot, the combo has been going 7 years now, no problem.

Is this the original one that is hard to find?
