"Clangy" bucket on a 3CX

[Shovelhands]

Not sure what to do about this problem now. It is the bucket that I use most nowadays and in fact I think it is the third 3CX that I've used it on which might explain why I have the problem. If I was still contracting then it would probably be time for a new bucket but I will try and think of a cheaper solution.

Would a new set of bosses in the bucket lugs be an option for you? Burn the old ones out and weld some new ones in? New set of pins can be had from Vicary Plant for fairly reasonable money. Would tighten it up like new, especially with a new dipper end bush.

Yes, I think I can see where you are coming from and it is indeed a possibility. Fair bit of work and I would have to make sure that the new bucket bosses were all lined up correctly before I started welding them in the bucket flanges. I have yet to do a detailed inspection of the dipper end bush/pin play and I intend to proceed on to that tomorrow.

If you are worried about getting things lined up you could see if @CPS would do you a pair of cheeks then cut the whole lot of and weld the new cheeks on with new pins inserted. Cheaper than a new bucket but quick and easy to do.

Almost got the same issues though, getting them lined up. Its sometimes actually easier fitting the bosses last anyway, as you don’t have to be quite so worried about the cheeks plates pulling when they are welded.
In any case, a new set of pins is essential, for lining up the new bosses if nothing else!

Thanks guys but not operational today. Covid booster yesterday and as usual I'm feeling crap today.

Just buy a new bucket from me
I have a couple of genuine JCB 30” on pallets waiting for a new home

You can PM me with a price if you like.

was going to suggest new bosses too, but didn't know what the OP's facilities were like to do it

I have a purpose made spacer for welding cheeks on - 200 x 100 x 12 RSA cut accurately to size ... set them up on the bench, clamp the spacer in with some card for removal, then stitch some braces on for the transfer and hold everything solid


it's also handy for single cheeks .. same MO .. set on the bench and transfer


My V block is also handily just the right size for my narrower requirements for my VA-r cheeks

Nice bit of engineering there.

Ok, this is not the right way to fix this but I think it will probably be ok for what you want without expense.

Take the bushes out of the arm and find a bit of bar / pipe / plastic / wood etc that is the same size as the OUTSIDE of the bushes. If you can’t find something the right size use something a bit smaller and build up the diameter with turns of tape wrapped around it.

Put the bar in the arm and see where the wear has occurred. Remove the bar put some weld in the arm on the low spots a bit at a time.

Keep testing the hole with the bar between applying a bit more weld to see how much you need to build up and where. If you overdo it a grinding wheel in a drill or better still a die grinder should take the high spot off.

Hopefully by doing this you will be able to get the bores in the arm back to round enough that there is not too much slack and the bushes are supported sufficiently for them not to crack up during use.

Good luck.

unless the bushes are shot, the dipper end bore should be OK ...... it's his bucket bosses that're banjaxed Rob

Sorry, didn't pick up on that.
