ksfarmdude Posted March 21, 2021 Share Posted March 21, 2021 Yep its toasted . Do you do a lot of spinning in muddy conditions pulling heavy loads? Haven't seen one worn quite that bad I know others will jump on me on this but I'd start running that tractor 5 gal over full on hytran when your done Link to comment Share on other sites More sharing options...
Mighty1206 Posted March 21, 2021 Share Posted March 21, 2021 Make sure you have the right gasket between the TA housing and rearend. If you have the wrong one in there the diff won't get proper lubrication. Link to comment Share on other sites More sharing options...

But it has been almost four or five years using this tractor every spring for nearly three hundred acres of corn.. I know it's not a lot to some. It doesn't have any sight of overheating, i.e. blued edges. Link to comment Share on other sites More sharing options...
J-Mech Posted March 21, 2021 Share Posted March 21, 2021 Common problem on a 15 series. Yes, make sure it has the right gasket between range and speed housing. If there is any question, split it to check. Different carrier is junk. Get a used one from anything but a 15. No need for more oil. Wouldn't matter anyway. It can't get inside the diff unless it was at least half submerged. No holes in the housing for oil to get in. Link to comment Share on other sites More sharing options...
Thesd5488 Posted March 21, 2021 Share Posted March 21, 2021 Diff is pressure fed I think been awhile but it could have a steel line feeding it on left side Link to comment Share on other sites More sharing options...
Diesel Doctor Posted March 21, 2021 Share Posted March 21, 2021 We done 26 of the 66 series with the differential recall in the 70's. We found when setting the ring and pinion, use the tighter clearances for a quiet rear end. When you go to the looser side, that is when the differential noises start. The inside of these are basically the same but I can see many changes from my time. Link to comment Share on other sites More sharing options...
856 Custom Posted March 21, 2021 Share Posted March 21, 2021 Yeah, that's past it's prime lol! But we're dealing with something that's 42 year's old too. Those tractors aren't new anymore. Some of the die hards seem to forget that. Link to comment Share on other sites More sharing options...
ksfarmdude Posted March 21, 2021 Share Posted March 21, 2021 I can't help but wonder , I bet with all those worn out differential parts I'd think it would sound like a corn sheller turning or spinning a wheel Link to comment Share on other sites More sharing options...

It didn't make any noticable noise. I doubt I have the wrong gasket in there because it wouldn't have made it four years... If I would have put wrong gasket in there, everything would have let loose sooner. Link to comment Share on other sites More sharing options...

I've pulled several 15's apart before that looked like that. Most operators catch it before it stops moving, but not all. Last one I did, guy quit using it and we got it in just in time. Hadn't chewed all the way through. Once it starts to eat itself, it goes fast. Link to comment Share on other sites More sharing options...

Didn't I read that? That's not many. Think I also read where you don't pull anything big with it. At the very least, I'd put a gauge on the lube circuit. Honestly I don't know how someone would put in the wrong gasket unless they just weren't paying attention. Link to comment Share on other sites More sharing options...
MinnesotaFarmall Posted March 22, 2021 Author Share Posted March 22, 2021 Yes, it's not been abused, in no way or shape. We treat our machinery very well. I am tempted to put a hair on it, because last time I drove it, I sort of remember it seemed like the steering was hard to turn. I will check the lube pressure. I did pull the three point link cover and remember seeing oil come down around the differential carrier too with it just idling. Link to comment Share on other sites More sharing options...
MinnesotaFarmall Posted March 22, 2021 Author Share Posted March 22, 2021 On the gasket subject, I'm sure it's the right one because I ordered the gasket kit from case ih for a 1586, and had to give them the serial number. I checked if against what was left of the old gasket and only remember one hole going through the rear end. Link to comment Share on other sites More sharing options...

I did pull the three point link cover and remember seeing oil come down around the differential carrier too with it just idling. Steering hard as in difficult to turn the wheel? Or as in needed brakes to steer it? Both issues were likely related to the chewed up diff. The debris was plugging, or had plugged off the filter causing the hydraulic system to have low pressure due to starvation. Turning it, the differential would not have wanted to spin as it should. Binding up. Lube pressure and steering pressure are two different circuits. They are related, but steering pressure can be fine while lube is low. 16 minutes ago, MinnesotaFarmall said: and only remember one hole going through the rear end. The hole is in a different location on a 15. If a smaller tractor gasket was used it would partially cover the lube hole. Not completely as I recall, only partially. Other than that, they are pretty much the same. Seems like the 15 also has a zigzag cut out on it to lube the reverse idler shaft, that was cut slightly different than a <15 gasket. But at quick glance, or comparing to a torn old gasket, you wouldn't notice. You would notice when you stuck it on *IF* you were paying attention.

MinnesotaFarmall Posted March 22, 2021 Author Share Posted March 22, 2021 I'm certain there was only one gasket in the kit, and I do remember it being completely open. Turn the wheels as in the effort needed to turn the wheels. Once wheels were turned it turned ok untill it quit moving. Link to comment Share on other sites More sharing options...

MinnesotaFarmall Posted March 22, 2021 Author Share Posted March 22, 2021 I know you said not to, but we need some more parts off of it. Would the planetary parts be the same from a 1566? I'm mainly concerned with bevel on the gears. Link to comment Share on other sites More sharing options...

MinnesotaFarmall Posted March 24, 2021 Author Share Posted March 24, 2021 Exactly why I took the whole rear end. The local yard and I have a good relationship. I bring the whole thing home, bring back what I don't need and they of course get paid honest and fair. Here is the new rear end diff. Cross is stamped ih, and it honestly looks nearly new. Some wear on gears, but nothing on housing or anything major. Link to comment Share on other sites More sharing options...

MinnesotaFarmall Posted March 26, 2021 Author Share Posted March 26, 2021 It literally had .001" of wear or less. No galling, no worn spots. Link to comment Share on other sites More sharing options...
MinnesotaFarmall Posted March 26, 2021 Author Share Posted March 26, 2021 Set up shims on differential. Measured via blue ribbon book and got .090" for shim value. Set up shim pack and installed it. I can get .011" backlash, but if I shim it up tighter but retaining the .090" value for preload, the ring and pinion gets offly stiff, and doesn't turn well. I think I'm going to stick with the .011" backlash as it is in spec of .005-.015". Link to comment Share on other sites More sharing options...
