Nothing to leak on the wheel side so has to be either the oil seal at shaft output or the x-ring that seals the pumpkin cover. I would first pull off the wheel and inspect whether leaking from where cover bolts onto pumpkin or oil seal. The oil seal might be able to clean. Sometimes dirt gets under it preventing a tight seal. Try putting something very thin under the seal and move it around the circumference trying to scoop any dirt or grit to the outside. Very thin like a feeler gage, 35mm film, etc.steve68steve said:I brought fluid, I'm going to crack it open and see how low it is. Hopefully it looks worse than it is.
What's frustrating is that it leaks continuously. It leaked on the trailer strapped down for 3 days. If it really is a severe leak, I was thinking of taking it to the local yam dealer here in Cortez. Don't know how likely they'd have parts in stock. Seems like it would need more tools and space than a camp site could muster, but if you think it's doable, please bring whatever you have. Fwiw, I'm pretty sure it's leaking on the wheel side, not the shaft side. I had it all apart and cleaned up before I left. The shaft side looked dry. The wheel side didn't.
I've had final drive leaks that made an ugly mess over the pumpkin and wheel and rode 1,000+ miles like that. When fluid checked it was only low by an ounce or so.
Oil seal can be replaced blind without removing the cover. Drill a small hole, thread a small sheet metal screw into and and grab screw with pliers to pull out seal. Drive the new seal in using the old seal and fill up with fluid. Pumpkin cover x-ring is easy but Torx bit is required. I will bring one if somebody can tell me the size. I wont have my rear wheel off before coming to check what size the Torx screw is.
If leaking on the trailer that is bad. Mine previous leaks usually showed up over high speed prolonged riding, maximum heat and centrifical force made worse.
