A good feeling

Last spring I could hear a slight tick in the rear end of our 1486 occasionally, only when backing up. I chisel plowed with it for a couple days, then I found that I could noticeably hear it/feel it when pulling. I quit using it for the tillage and used the other tractors, but decided to see if I could figure out where to go after before I parked it. I jacked up the rear end and blocked it off the ground, removed the 3 point top link cover so I could look into the rear end, and had dad get in it and run it. I had him put it in low gear so I could look at the ring and pinion. They looked great, lots of lube oil being sprayed on them too. So I had him put it in High 3 and hold the right brake while I looked in the housing and used my stethoscope. Nothing on the left side. Had him hold the left brake in High 3, bingo. Noisy, and clicking. Good deal, probably just a bull pinion, bull gear and all of the bearings in there. Good deal, I put it away until I had time to tear it apart. Drained the oil out of the left final, transmission, and rear end center housing, and were clean as could be. Drained the oil out of the right final and picked out metal with my magnet, looked more like bearing than gear, and didn't get any big chunks. Got the final off, and lucky me, it just needs a bull pinion bearing set, and an inner axle bearing set. I'll also put an axle seal and brakes in it while I'm already here. I already have the brakes done on the LH side. Makes me feel pretty good it is even better than I thought, that NEVER happens here.

Nice when everything comes together like that !

Way to go, Ross! Good catch...

Nice job troubleshooting - It's a good feeling, when it turns out to be not as bad as you thought...
I've got a noise in my 2-105 that I haven't pinned down yet - it's got a pretty good howl, but only in 6th gear

As others have said; excellent diagnostics (an increasingly lost art).

Good catch. If that was continued to run that way, would have cost a lot of money.

It is good that you had your Dad in the cab to help. It is hard for us singles to pin point something like this by ourseves. Good work!

The looks on the bearing would show??? Water damage- poor heat treatment- over heat, What do you think. Glad you caught it.

I almost had to run it more at first, it was so intermittent. Once it got where it was making noise consistently, it was much easier to find. There's a pretty fine line where you COULD still run it, and when you SHOULDN'T still run it lol.

No water in the rear end... Guessing it maybe caught a piece of something, maybe a flake off a gear tooth? It has Bower bearings in it, which will be replaced by another USA bearing. The inner axle bearing and race together are about $175 at Case IH. But, on EBay, there is old stock Bower, SKF, and Timkens, all made in USA for about $20-40 for the pair. Old junky boxes, but as long as the bearing is still in the wrapper and says USA on it, I'll buy it. I've had VERY good luck buying NOS bearings on EBay, and saved a lot of money too.

Yep, I'm normally a one man show, but he happened to be here during last year's spring work, while we were moving equipment back and forth, so it worked out well. I try not to ask him for help if I don't have to, he's worked hard his whole life and doesn't need to be helping me since I'm usually able to do everything myself. Although, if I asked him to help, he'd be over at any time at a moments notice, but I don't like being like that.

Ross

Good catch. What does the other part of the bearing look like?

Actually, not bad... Has some real light indents in it from pieces of the bearing, I was quite surprised it was no worse than it was. A lot worse after I put a weld on the race to pop it out lol.

Ross

Thanks John!

Yep, you're right Jack.
I figured for sure when
I first heard it, that
it was something in the
bull gear or bull pinion
on that side. Those big
gears are pretty pricey,
and I've heard that when
a 1486 loses an inner
axle bearing or bull
pinion bearing, they are
more likely to ruin the
bull gear than the
smaller ones for some
reason (same finals).
That's just what I was
told.

So where does the power come out from the transmission the top hole? And when did ih go to planateries ?
