Trying to remove a stubborn pin on my Volvo loading shovel,had a pepper pot burner warming the boom up but can't get it to shift.

The pin in question is about 100mm in diameter and the booms probably 75mm on each side,we've had a 20t bottle Jack pushing on it but nothing is budging.

All suggestions appreciated,Tia Scoff

Just done one no long ago and had to burn the centre of the pin out! She was seized solid, I had borrowed a mates 100t Enerpac, and used heat. Still wouldn’t budge

is it on the boom or tilt? Forget th heat for a start, load the pin up with the jack, get a great big piece of solid bar for a drift, a fourteen pounder and some animal to swing it, and drift the frame/tip link or wherever it is in the opposite direction to the Jack. Keep pressure on and if that don't work, then get the heat out but try to keep it off the pin.

I had one a manitou telehandler had it red hot on the bushes with a 20 ton bottle jack would budge:mad:
Even had a jack hammer with a flat tool on it :mad:
Ended up cutting the pin ether side to release the greased part of the pin then burned the two pieces of stuck pin out(y)

Center pin on the GDF link (middle link with the 3 pins) on an L70 by any chance?

Yep,you know they are bad to shift?
I've taken the boom/arms off now so should be a little easier,I hope!

Well we got the pin out in the end,3t mini with the breaker wouldn't move it at all😪

Ended up lighting my brothers forge under one side and heating the other with the pepper pot,3 of us taking turns on the sledgehammer,it's taken about 6hrs to get the pin out,my wrists are aching and my head is banging time for a whisky or two.

I Thought I had replied to this but still getting used to this new site:) This is how I moved them, 60 ton hollow ram 30mm high tensile threaded bar. The L70s are the worst to do, the frame is to flexible and you don't get the full force of your hammer or pullers. What i do is cut some bars and jam them the 2 frames, keeps it solid.
