JCB 3cx stuck pin.

Post #1 by mechman » Sat Oct 15, 2022 6:25 pm

Hi all.
As title, we've been trying to remove the boom to king post pin for the last 4/5 Saturdays and today was the day of reckoning. Tried all the usual routes, heat etc, so today we used a 30ton jack (porta pack) and the O/A gear and the 7lb sledge hammer. + we burnt the pin out of one end. I've never come across one as stubborn as this, anyway the barstewards out.
Norm.

Yes this one took the biscuit though. Forgot to photo the offending article when it finally surrendered.

I have a pin to remove on my Manitou /NH handler. You can't even get on the end of it. It is on a tipping link and someone suggested cutiing out with a slot disc. Trouble is I doubt I can get to it with a disc of any size to get right through.

Hi all.
Fixing boom ram, and fixed. A little mechanical help was required.

There were 3 of us involved in this delicate operation.
Norm (and 2 others).
