Hello, I’m new to the forum And have a question. I’ve got an R420 that I picked up dead. I’ve weeded through enough issues to get it running. The steering works, the lift works so that tells me the pump is working. The moving sequence was initiated by someone else. I replaced the washers for the brake as noted on the cover. The acorn nuts were removed and the lock nuts were loose On the Hydraulic motor. The nut that was not to be moved appears untouched and is tight. From the picture on the cover, it looks like there is a center nut that should have been turned, not the acorn nut with the o-ring. Any ideas on where to go next. The machine isn’t a major priority but is in the driveway and I’d like to move it to the shop, under its own power preferably. Thanks in advance!
