Geoff Weeks Posted 19 hours ago Share Posted 19 hours ago Do you have a cylinder chain vise and a HEAVY work table to bolt it to? without those it is impossible to repair some cyl.

Sometimes heat and an air hammer gently going around the outside of the barrel where the gland nut threads are can help loosen them up and then a GOOD spanner wrench to get the gland nut off....but it can take a while. Good luck! Quote Link to comment https://www.bigmacktrucks.com/topic/76188-91-case-580-hydraulic-cylinder-disassembly/#findComment-586206 Share on other sites More sharing options...

RoadwayR Posted 10 hours ago Share Posted 10 hours ago Yes, if you have room try to loosen the gland nut before you take the cylinder off the hoe. Use the exact right size spanner, but you know that. Light air hammer near the threads is a good idea. And lots of penetrating oil. Been there, done that. Love old 580's. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/76188-91-case-580-hydraulic-cylinder-disassembly/#findComment-586224 Share on other sites More sharing options...

Might make a sleeve for the pipe wrench! With a hook on it and maybe be use the machine to power the wrench chain off to a stump and put pressure on it with the hydraulics and air hammer as suggested! The out riggers will have change tactics if it works! Will see! If I can break it free and get some oil flowing around it things may get moving! IF it works!
