Have the pin out a question about the pin that's out is tapered at the bottom is it supposed to be tapered from the factory or has someone been in this final drive before hard to find specs on it.It's the pin that locks the nut that goes through the hole in the nut.Thank you.
UH123 dowel pin # 4138498 . IIRC the dowel pin is the same diameter at both ends. I assume someone put a taper on the pin to help guide it into the lock hole in the ring gear.
Thanks Diesel Dave you know the Hitachi did you own one.That pin seems to be impossible to get.I have a friend at a machine shop going to make one.Now I know someone was in there before because it was tapered.The cone seal was busted up that was my leak seals came today going too replace both Igot it apart.Got some new bolts everything cleaned all thread bolt thread cleaned bolts soaking in cleaner.Once again thank you Timneh
Never owned one but turned wrenches for years at the Deere dealer. Do you have the torque spec for the large nut when going back together ?
No but I made the tool to take it out I know it's alot
seals came today from California there the exact match i was nervous but when you have me the info and schematics on it i was able too get them the machine is old me and my partner aren't afraid to fix and get dirty we have the tools I've been wrenching also since a kid not like you your a master mechanic
My partner can run any piece of equipment he grew up in the Washington Valley of New Hampshire work on the ski trails.I ran rosier but mostly rock crushers on rental through out N.H a lot of town accts made there 2inch minus for there class 6 travel roads

The UH123 final drive bearing nut, hub and bearings are the same part numbers as a Deere 792 straight. Maybe @LACHAU or @mg2361 could dig up the torque spec for the final drive bearing nut.
It was a hard job on the crushers always keeping a close eye on metal going in the jaw.Had a old 20 lb sledge hammer head rusty could pass as a rock got in the jaw and all hel l broke loose belts squilling.Took me 4 hrs with the torches to free it lucky it didn't break the the bearing.No fun with your arms and head in the jaw on your belly.Don't miss the crusher.
For a 792 Deere, the spec is 289 lbft (392 Nm). After first tightening, rotate several revolutions, smack the nut a couple of times with a brass punch, torque again to same spec. Align nut with hole, insert dowel, making sure it is countersunk below nut 11.5 mm.
Thank you everyone
