Need a dealer for 4110 Parts !

[skipmarcy]

I need a dealer that's good with parts for my 4110, my selling dealer is no longer a Mahindra dealer. In the 5 years I've had my tractor I've broken probably 7 or 8 front axles and 2 countershafts, I keep a spare of each on hand. Last I talked to a tech at Mahindra a couple years ago he said I needed to run the front tires as hard as you can and run the rears low - they got the ratios off or something in the diffs. Anyway, thought I had popped another one but it wasn't this time. I need the 4 studs and 3 indexing pins that attach the ring gear to the carrier in the differential - snapped them all off. Luckily no other damage, just some cleaning to do. I need these studs & pins ASAP, will pay overnite freight to have them drop-shipped to me, hopefully they are in the States.

My tractor serial number is 411-U03-0043. I believe it is a TYM axle, the replacement axles I've bought are TYM, part # 14254330030. The front axle the service manual I have shows is not the same as what I have. If you can get these parts for me, I would like to also get the 2 outer tie-rod boots (been on & off too many times !!) and a fuel filter and an air filter.

Skip,
I sent you a PM. Thanks!

I find it interesting that they tell you to add air pressure to the fronts. If you can get extra circumference that would make the fronts spin faster. If you are tearing front drive parts, maybe less air pressure would let the parts live longer since it would'nt be pulling as hard, due to the smaller circumference.

Maybe I am not picturing this right, but what do you mean by "spin faster?" Increasing the circumference will have to reduce the RPM'S if you assume the same engine speed. The front wheel will have to travel further to make one revolution. The ground touching edge of the tire WOULD have a higher velocity caused by the increased circumference, but this would not have much of an impact. This may be completely off base, but this is just how it processed through my head...

As far as the tractor... what are you doing to this thing? I sense from the tone of your post that you recognize that you are abusing your machine and expect to pay for such repairs, but this still seems excessive.....

Oh.. one other note.... your dealer should still be able to service you with parts, but Mahindra's policies make it a little difficult for some of that. I don't know how other companies handle dealers that are no longer in the flock, so this is not a knock on Mahindra. How they handle this may be completely normal.

Yes and no - I have what most people would call abused my tractor at times but that is not the underlying reason I'm breaking axles. The first one I broke was within 2 months after purchasing my tractor and I was definitely still in the "babying" mode - extremely careful, no heavy work, mostly cutting the grass. When the axles go, they pop pretty good, I know exactly when it happens and yes, a couple times I was doing some heavy duty loader work etc. But ... with several of the breaks it was under perfectly normal duty, usually while dragging a load of dirt in my 6' boxblade. These axles are snapping right at the point where the splines start at the outer end of the axle, where it has been hardened. The final drive assemblies are fine, no bad bearings or slop etc. etc. Have been over this problem with Mahindra reps. many times with what I posted as their final solution. In all but one case, it's the left axle that pops, this is the ring gear side of the diff. Both countershafts that have broken were in the right final drive, don't quite understand that one, there again all tolerances within the final drive are just fine. Now the studs in the ring gear have broken, don't know if it's from all the stress and popping axles or the fact that they didn't use Loctite to install the studs in the ring gear. When I reassemble the diff., I'll use some and torque the nuts and I'd be willing to bet I won't be snapping these studs again. Same thing with the problem I had a couple years ago with the engine to plate mounting bolts backing out and snapping off - they didn't use any Loctite on the bolts and couldn't use loc washers because of clearance behind the flywheel so the bolts backed out and several snapped off. Since I repaired that problem myself 500 + hours ago and got the loader braces my tractor never had on it from Mahindra I have no more problems with that. My tractor is a pretty early production, don't think they had it quite down-pat at the time. All I can do is fix the problems as they arise, can't re-engineer the whole tractor. Got 1252 hours on the clock and it still gets the job done, I can change an axle in 15 minutes if that's all I have to do once or so a year.

Wow. All of that is quite impressive. More than I am capable of for sure.

I don't see how changing air pressure is going to make that much different in the circumference of the tire to effect your gear ratio, it never affect my old 4wd truck. Now, if you had the wrong size rims and tire then I could see a problem. Also, if you do a lot of driving on hard packed soil or roads with FWD engaged then you may be loading up the front end. But, I think the tech you talked with is at a loss and is blowing smoke, maybe I'm wrong but have you found this problem in any other Mahindra threads. But, I have a couple of questions for you....

1) What type of tires are you running
2) Are they breaking when turning under load

I agree that I do not think it's a tire pressure issue either. I was more trying to question the credibility...
Something sounds fishy to me on the whole thing, especially since I have never heard of anyone else having this issue.

My tractor was delivered to me with the Titan R4 industrial tires, which are still on there. The max. pressure rating for the front tires is 40 psi, I've always run right around 36 - 38 psi as I do alot of loader work. The first couple years I was running around 16 - 18 psi in my rears, since the rep suggested I run lower I've stepped down the pressure in stages - tried 12 psi, then 10, now I'm at 8 psi. None of this has ever had any effect on the axle problem but I am happier with the better traction I get in the rear with the lower pressure. By the way, my rears have been loaded to 3/4 full since new with methanol mix, not that this makes any difference on the front axle problem. I just hope I don't pop a tire bead loose running at 8 psi, don't really think it's likely but anything is possible. It's crossed my mind before that since my tractor is early production it's possible that the diff. ratios were for R1 ag. tires or so - much larger diameter tires - just a guess.

Once or twice the axle popped when turning sharp while either dragging a boxblade full of dirt and/or moving a bucket full of dirt, but they have also broken at what would seem to be perfectly "normal", straight-line operation. One time in particular I remember climbing a large pile of dirt to get on top to start dragging with the box and the left front wheel came off the ground spinning and then when it re-engaged the pile it snapped - this is the one time it didn't surprise me at all. What has baffled me is the fact that the axle is snapping instead of weaker links in the front drivetrain. Where the break occurs every time is .985" diameter. Seems to me either one of the two couplers on the front driveshaft would break before anything else - they are n't much more than a piece of pipe with splines cut inside them - wouldn't take too much torque to split one and let the driveshaft spin inside it. Now that I've had this ring gear stud problem I've got to wonder if they've been loose since very early on from lack of loctite and the slop & shock load was contributing to the axle breakage. The axle that breaks is on the ring gear side. Only time will tell after this repair. And yes, I've set up many, many differentials in my 34 years as a pro auto mechanic so it will be done properly. I've always been very meticulous about maintenance, including little items they don't tell you about in either the owner's manual or shop manual. Even with all the hassles I've had with my 4110, I still like the tractor and would probably buy one again - from what I read here they've gotten alot of the kinks out of them. Most everything else about my tractor has held up very well and I forsee many more years of service from mine. I don't have a single leak of any kind of fluid, the engine starts no matter what the temp. and as long as it has front drive it will do everything it was designed to do.

I must say I am impressed with loyalty here. It's very nice to see you talk about repairs that would be pretty major for most of us out here and not sense the slightest knock against the Mahindra at all. Too many people would have disowned the tractor by now. It's still a tough, well built tractor. I would love to have one myself. Good luck with your tough little booger. Hopefully you are right and these loose studs have contributed to the issues and they start to go away now.
