Trying to repair a smaller hydro cylinder on a boom lift. This is the "master leveling cylinder" for the basket. It runs at the very back of the machine. I cannot pull the top pin without running the boom to the moon and I am not sure what the basket is going to do. I figured I could just leave the rod and its pin in place and just pull the barrel and do an "in situ" repair.
Well I can't get the damn head off! this is a screw in type where the head screws down in the barrel. I cannot find a friggin set screw but there are 4 pockets in the head for a proper spanner that someone already beat up. So I tried that. That head will not move at all! Never had one stuck like this. I know there is not a grub in the top, but I studied the sides for 30min trying to see if there was a grub in the side. Just cannot find one.
Anyone ever see a cylinder with no retainer on the head? I am hoping I am missing something here.
