Thanks. I can do those two jobs (just bought a welder), do they have perfect circular holes where the bush goes? Thats the main defect with mine which I can't see me doing with a welder. I think mine has been without a bush for a long while and the ball he worn the inside of the hole unevenly which may be why it doesn't hold onto bushes even when clipped in.

if it wont hold a ball and nylon cage with snap ring its buggered, and ill send you one of mine to weld up and change pin on
Well i think it's holding one, it did snap in, its only slightly out of shape around the top, but i THINK the previous owner told me when I bought it (8 months ago) that he had JUST replaced that bush, and the gear problem turned up after only 1000-2000 miles so my thinking is that its out of shape enough to let the bush work loose under load, hence yeah I reckon its worth welding up the ramp and changing pin on one without a worn hole! Thanks!

Mine is also worn (did not have reverse light), I also wanted to remove and weld, but the screw fixing the yoke to the shaft could not be moved (even with special heavy duty tools) and before causing any bigger damage on the shaft I gave up and made a longer reversing switch
As yours already out you can try to weld, but take care of too much heat and possible deformation (but in worst case you can get an other one from james).

yes
Well jamesmartin is a true gent. Sent me a second hand yoke. I have to fit new pin in it. I bought a pin but it goes in loose, i was expecting to need to grip it in vice to press it in but i can pop it in and out with fingers. It will obviously drop into gearbox so wondering what best way to secure it is, if anyone knows? Weld is the only thing I can think of, assuming it's gotta be solid so it doesn't drop into gearbox. Any tips appreciated
I don't know. Don't want to guess at it considering what happens if i feck it up and it falls out! I always thought loctite worked inside a thread, not sure it will secure two smooth pieces of metal together especially in such a sensitive spot. Not sure how much clearance the top of the selector pin needs, a blob of weld at top of it (under the yoke) would be good, but it might foul the gate. not sure yet, but anyone who has had to do this when it wouldn't press in, please shout!

What held the pin in place originally?? Is it an Interference fit where the pin is a few thou bigger than the hole. We used to have a wee trick where you dabbed the pin or shaft with a centre punch and the raised edge of the mark held it tight.Well jamesmartin is a true gent. Sent me a second hand yoke.

Thanks, yes its an interference fit and that sounds like a neat idea, if it works! all new to me this! so you would smack a punch onto the side of the shaft on top of pin, so it grips when pushed in. Interesting!
Also interesting, I have just removed the top of gearbox again to go at this job and get old yoke out. I see creamy residue on underside of top plate (as i noticed last time i removed it) but this time I also see RUST on various bits inside. Should I be as worried as I am about that?!

You have now exposed things to air. If there’s moisture on the surface of any non ferrous metal when exposed to air you’ll get rust !!
in a gearbox with oil in it? lid was only off for a day! either way, should i be scrubbing thatt rust off or just get it done and sealed with new oil asap?
thanks
