Ok let's say I needed to add metal to a worn clutch arm, I am sure it has been mentioned on here before,

So crack up the MIG and add metal. Grind/file in round. Anything else needed to be done?

Or who can find me a Metro cable operated verto clutch arm.

I have three and picked the best but was thinking can I make one like new.

It will be too soft. I would finish to the job by carburising the face with an acetylene torch. And quench in oil.

I've re-done them with a 'Stick' type Hard Facing Rod, a bit of work to grind back but last a VERY long time, longer than the plunger.

MIG weld often turns out to be annoyingly hard and may be adequate in the short term. But as above, hard facing rods are available in small quantities from your local welding supplier. Carburising in a flame is very good but only for those who know what they are doing. You or I may end up making it brittle.

Good luck with your efforts.

Wouldn't buying a new one be easier and more cost effective in the end

But that is not the one needed.

Like I said cable operated Verto clutch arm. Your link is for a Mini hydro verto arm.

That is the problem.

Ah, I thought you where running hydro still, but cable was a potential solution.

Ok found some one selling new and got someone seeing about availability long term.

Interesting is people selling used ones never post images of the contact surface side do they look new.

Might get the lad to get a new one and keep the best of the three as a spare.

But it seems the cable set up copes with wear better than the hydro when looking at what came out.

I had a thought about this last night while driving home. I would tentatively suggest using a nice, sticky, long life grease on the ball in future to hopefully reduce wear. How about Molybentone as used in CV joints? Just a little spot.

Having said that, I never wore out a ball end in 250k miles in 3 Minis, 2 of which were Verto and one the ancient coil springs. Few do that sort of mileage these days in what is now a classic car, which suggests that the problem starts with elapsed time rather than mileage and so is likely due initially to corrosion rather than wear. Make of that what you will. Maybe worth removing, cleaning and greasing every year?

A method of preventing the ingress of moisture and dirt would also be good otherwise grit, rust etc acts like a grinding paste

I have been dipping the ball ends in Molly Grease for a long time and it does help a lot, but I also shove some sponge rubber in the top of the slot for the arm too.

Try speed foam.
