In Reply to: Re: Case 530ck backhoe upper pin removal posted by AJ on Wednesday, December 28, 2016:
I've tried quite a bit of heat and there isn't room underneath to get a jack, that's why I used a heavy C clamp with the heat. There are a bunch of hoses coupled to the swing tree tower between the upper and lower pins and these would have to be removed to get a jack in there. I have used a sledge hammer with moderate blows from the top to no avail to try and knock it out the bottom. I also hit it from below with a heavy hammer and steel rod. I had thought about dry ice on the pin to shrink it. I don't want to make things worse by putting to much force on it, however I'll keep trying and if there are any other ideas out there let me know. Thanks for the warning on the oxygen and oil, I had forgotten about that.
