Sounds to me like your cable in the console has come loose from its holder. We had the same thing happen in an 8070 power shift. The cable was held in with a zip tie. It just got old and brittle and broke. It was easy to fix.

If the short shift lever under the cab floor can move side to side (the neutral position) AND the tractor will drive/move in what seems to be low range, I'm afraid there has been a seizure of the low range gear to the pinion shaft. This is how I'm interputing your description of what's going on.

This is a big deal. That seized gear will have to be torched off of the pinion shaft and hard gears don't really cut well at all. It will require a different ring and pinion and any gears that get damaged from the torch work.

That does not sound pleasant. Let us know how the rebuild goes.

8050 ring and pinion and seized gear should be the same as 7045/7060/7080, but I'd want to do some part number checking to be sure. 7030 ring and pinion not the same I know.

I'm no help with the repair, but since it has a Cummins repower in it, have it dynoed so see what it puts out. If it's over 200hp your going to continue to have problems. I've been down this road with a 7080.

Seizure of a range transmission gear doesn't really relate to the engines HP. It is the seizure of a free spinning gear on the pinion shaft. The gear that seized isn't even being used. For some reason, there was a lack of lubrication problem somehow. The Cummins 8.3 transplant would probably be more likely to cause main transmission problems on the input shafts when equipped with a Power Director transmission. If you always ran 5th gear LOW button the main tranny could only fail if it twisted off the input shaft, which I suppose it could, given enough torque going thru it.

Most likely cause for seizure is dirty oil or has set for years then taken down the road in HI range. MACK

Is the tractor with the possible seized gear a 2WD or FWA model ??

I'm pretty sure a FWA pinion is different than 2wd, if it is indeed seized.

I agree with the good Dr. - and it is a BIG JOB - might suggest Heitman tractor or google 'dismantled 8050 Allis' and get an entire rear end assy. I would say one is looking at 60-80 hours labor plus used parts anyway. Has to be FWA of course for all doner parts.

Update: just pickedup 8050 from local repair shop, apparently short shifter under seat was wore enough to jump out of the shift gate,also the cylindrical pin that is in the shift rail slots was wore on both ends allowing too much slop.
So they replaced cylindrical pin,did machine work on all worn surfaces,and reassembled. Tractor is back in service. Thanks to all who responded,I really value your knowledge of ac tractors. Total repair bill $1123 |

I will give credit to Matthew and his crew at Stauffer Repair, they have been repairing tractors in a converted machine shed for 40+ years,they work on all colors not afraid to tackle any job, anything from log skidders,payloaders,riding mowers,rtvs etc. Usually 25-35 tractors waiting to be repaired.
