I saw a post recently on another site about a loose countershaft nut on a 1486. I know many years ago when I was real young, the countershaft nut fell off on the 1066 we have and ruined a lot of trans parts. I just wondered if there were any indicators of the nut becoming loose? Like maybe a certain noise, or anything to be aware of or looking for? I was only curious because we still have that 1066 and a 1086 and a 1486. All of which are going to be split this winter. The 1066 has needed a TA for years, but we haven't really used it much, the 1086 we bought needing a TA a few years back and we don't use it much either for heavy work, but the 1486 does all of the heavy work, and has developed a tick in the transmission. I eliminated one last year with replacement of the bull shaft bearings, but those covered up this quieter tick, that has seemingly gotten louder. Just wondered what symptoms a loose countershaft nut has?

Usually you will hear gear rattle that you have not heard before or they will just start getting rattly a little at a time. Most ignore it till it is to late . when i am into the speed trans doing a T/A once i get the preload set i drill the nut and install a 1/8 roll pin about a 1/2 inch long . Yea it is a little work to split at the speed and range transmission , not to bad a job unless it has a old style or year round cab .

pull trans brake housing on bottom of TA housing and look if shaft has moved or if spacers are loose. Had 826 year ago that had no 1st gear and what happened was the nut came off and the shaft slide forward out of the splines on first gear. Got a bar and was able to get it back into the splines. Customer not wanting to split the tractor at rear end to fix it right so I drilled couple holes into one of the spacers and welded spacer to shaft so it wouldnt move. Now this wasnt the correct way to do this and I was very against doing it but customer is always right(or so they think)
