I picked up earthmovers mag today, and in the back pages there was an ad for expanding/adjustable girth (steady on!) pins.
Forget all this grease gun malarkey and your fancy graphite impregnated copper alloy bushes - in future just get a bunch of these expandable pins and keep winding them. Everything now tight as a drum. Sorted!!

Got a link? Is it the swedish firm "expander pin" or have you found someone else?
Genuine expander pins are very good providing they are fitted correctly and there is no flex in the frame. If frame flexs then they simply will not stay tight!
I have used them on matbro and manitou centre pivots and there steering rams for years.
Also good for sorting jcb TM300 bottom main lift ram pin.
No good what so ever on a matbro main tilt compensating link pivot to boom they flex and no matter what the bolts just loosen off.
However they are very expensive.

Indeed it was the Expander System! 10 year / 10,000 hour warranty.
What do they say oil (grease) is the cheapest form of maintenance.....

Your talking £300 plus even for a small pin so that buys alot of grease
Warranty only covers failure of part due to faulty material not if pin wears part though which would naturally weaken it so it still needs to needs greased.

This video should answer everyones questions? I cant find the pictures of ones I have fitted? I think they may have been lost forever last time my laptop had a melt down!
you can skip the first 2 minutes they are very boring.

I guess they would struggle to stay put where the bore has become ovalled rather than a more regular circular wear.

no they will cope with 1.5mm oval. or if the oval is worn more than that you can grind a flat off each side of the sleeve or die grind the hole a bit more round.
I have not come across a hole worn bad enough yet that the standard sleeves cant deal with either.
they don't like a lip in the hole, so if say the old pin is not quite as long as the lugs and leaves a tiny unworn lip were the pin didn't come all the way through the lug you have to grind that out as well or the sleeves will not tighten up in the hole.
so long as there's no flex between the mounting lug holes in the frame then they tend to work very well. just they are so dam expensive! Don't stop you making your own version of it though out of EN24 bar
Tip don't make the sleeves from EN24 bar, EN8 is fine. EN24 is too hard and the sleeves crack

Like all good ideas it looks deceptively simple, but the devil is in the detail I have no doubt.just they are so dam expensive! Don't stop you making your own version of it though out of EN24 bar

Careful measuring is needed to get right lenght of pin yes. Too long and the sleeves not in the lugs enough. To short and they can push through the other side and interfere with the ram!

Final question, would expanders or line boring be your first/default choice?

Depends which i think is more suited.
Matbro centre pivots expander pin every time as so much easier and works really well. They are also awkward to line bore as you have to disconnect everything and stand machine on its nose or dig a hole to get room as you cant mount the gear on the top due to boom sweeps back over the pivot.
The expander pin option takes only slightly longer to fit than a standard pin.

I have had a alemite for 4 years and it been very good but the batteries have started to get old I have had a dewalt for about 3 weeks and so far I’m impressed.
Thanks for that one. Purchased it earlier. Hopefully better than having another branded set.
