Seems this is a perennial topic, and I'm the newest one in need of help. Thanks to KKeller's photos, and the pdfs, I've almost gotten my sticking stubborn jack disassembled.
Where I'm stuck is getting the inner tube out of the outer one. After taking apart everything at the top of the jack (gears, etc) I tried to pull that inner tube (the black one with the foot on it just to be clear) out of the outer tube. Totally stuck.
So I re-assembled and put the jack back on the camper and cranked it as far out as I could. Not easy, but it still functions with enough elbow grease on the manual crank. I hoped that getting it most of the way out, I would be able to pull it the rest of the way.
So I took it off the camper, disassembled it again, and have tried all the tricks I can think of to pull the two pieces apart. No success. I can't budge it a hair. Lots of WD40, lots of tapping on the tubes. Something is fiercely stuck.
Am I missing something? Something I need to remove before I can get these things apart? I hate the though of buying new ones because I can't maintain the old ones.
Cheers,
