has anyone changed the axle seals on a magnum fwa before. I have mine apart. Mechanic in at case said I should probably do bearings when I was picking up seals. One bearing is 1/4 the size of the other one. It’s screwed, 2 inches of the outer race is rough, one side on each roller is rough. The bigger bearing looks like new. Looks like this was made to be premature service. Seals and bushing looked really good. Now if big trucks were made like this they would have all the wheel ends done every year.

Premature service seems a correct term. From what I can tell is Case/NH and McCormick have a history of realizing their mfwd axle isn't up to the duty. Numerous axle changes/upgrades can be noted throughout production.
Front bearing went on my Mxm175 this spring. I heard something funny, kind of a howling but couldn't figure out where it was from. With 2 hours of spraying left then I had a 3 week window to look at it, I ran it till it started clanking and it was obvious then. Sent it to dealer and that was $11,000 to do one side. And the seal on inside of hub that was put in is leaking now too so need to remind them to come out and look at it again.

Ken I would lift the front end and check to make sure your wheel bearings aren’t loose that will cause a seal to leak. Our new holland T6030 would leak with a bit of play in the bearings. Happened a couple times after I replaced the bearings on the one hub. Must not have got them seated properly

FYI Hy-Capacity in Humbolt, IA has all the parts you could need for that front end significantly cheaper then CNH. Had one of the bearings on a mini mag 180 flake off at around 1500 hours, it's frustrating to say the least. Couple that with the engineer that put a snap ring on the back of the sun shaft instead of the circa clip that was there before, makes a not difficult job exponentially frustrating.

Sounds the same as kubota Cpt. Put a snap ring in instead of a circa clip, not fun at all. I have done wheel bearings and seals 3 times on the kubota, but it is 90% loader work. As soon as I see the seal starting to put a drop of oil on the rim its time to change it all.

I have a tm130 with the classIV axles (which are what would be in the mxm175) and I've done the big seals twice on each side, had the big bearing fail which took out the whole planetary and housing on one side at about 7000hrs, and had the other hub crack at around 8400hrs. Other than the first seal replacement I've done all the work myself. The replacement of pretty much the whole thing including the knuckle (that had to come from Italy) only set me back around $4000 so I'd say the dealer that did yours kenmb would have made a tidy profit. To the OP, I'd change both bearings and the inner bushing as well as the seals. Be careful how tight you screw that big nut on. You want to be able to turn the hub by hand. |

There isn’t a big nut , it’s got a plate that uses shims to set preload.

Yes, I should be concerned about mine leaking Meskie. It's under warranty and the service guy said they will look at it but that was back in November so have to get after them again.
Gary, I would think the tm130 has a smaller axle. It's a smaller frame tractor, but not 100% on this. These things get expensive, and yes, had a new knuckle installed too.
These row crops are just expensive to work on. I've been scanning ads a few days ago because someday I would like to get a case 9x10 or 9x30 to do most of the work the mxm175 does. A lot nicer tractor to operate and easier to work on, plus less crap to go wrong. In my mind anyway.

Those tractors sometimes have a couple different axle options on them so it could be different configuration in two different tractors. The NH parts guys always say they have trouble trying to finding the proper parts for the row crop tractors. Even with the serial number it’s sometimes difficult.
Our T6030 has a smaller hub but it was under $2000 in parts to put a new hub and then bearings and seals on the one side.

It’s got a 10 bolt hub. 215 wasn’t made for very many years there is a 10 bolt And a 12 bolt hub. Was going to change u joints. $600 for 2 u joints and they don’t have any. Seems excessive for a ujoint. |

I was looking at the prices for some of those parts, $4-500 for each of those bearings. I would have to agree, extremely excessive!
