IH 350 wheel bearing

Anonymous-0 · Jun 27, 2009

Well, I'mm getting most of this thing fixed, but I have another little problem.

I was putting in the rear axle seals, figuring the hardest part would be taking off the wheel clamps, and I wasn't disappointed. But having those off and one side done, I have found a loose bearing on the other side. It's on the furrow side and I know the seal has been leaking for some time, so the bearing must have been lose for some time.

It did surprise me to find it was a ball bearing, though.

Questions are:

1. How far can these go with play in them and what would you measure to decide when they have to be changed?

2. Since my first thought was to change it, my second thought was how to get that thing out without going into the bull gear setup. I don't like to use a cutting torch on everything, but is that a solution to taking the bearing out of the axle casing and off the shaft?

All suggestions appreciated.

the outside bearing would most easily be removed by sliding out the pto & removing the large bolt at the bull gear. You can press out the axle by backing out the bolt against a block up against the opposite axle.You must first remove the 4 bolts on the cap holding the outside bearing in.The bearing will slide off the axle easier if you will use a wire brush on a grinder to remove any paint & rust from the axle.All this can be done without removing the tranny cover.Murphys law states that if you don't drain the gear oil you will drop the bolt that holds the bull gear & you will drop your wrench several times in it.It is not as bad a job as one would think.
Hope this helps. Tim

Thanks a lot Tim. That does help - a lot.

I take it when I force the axle out with the large bolt you're referring to, a shoulder on the axle will force the bearing out of the casing and the axle will be in hand with the bearing on it?

About what will that bearing cost?

Thanks again,

Appreciate it, Bob

yes bob...after you take the cap off the outter axle bearing (4 bolts) and put a block inbetween the bull gear bolts...use a open end wrench and back the bolt off this will pull the axle outwards and eventually will come right out...I just did the bearings in mine...I found a local bearing house near me was cheaper than case ih, i paid 62.75 for the outter axle bearing (st-227) and 34.95 for the inner bearing (st-328) i dont have the numbers in front of me but case ih was between 75-80 dollars for the one bearing and i believe around 90 bucks for the other...good luck!

Hi Bob,I replaced the furrow side bearing in my 350-in a very cramped shop in about 3hrs and I'm crowding 80 ---so not to big a job as puller explained.
The new baering cost me 80 odd at the local bearing house. Good luck John

Couple of things...a bearing can be "loose" in one of two ways...first there can be wear issues between the inner and outer races, straightforward fix is to replace the bearing.

However, a more serious problem is that the inner or outer race has turned either in the housing or on the shaft (seen both over time on ball bearings used in other types of equipment)...which would then require some repairs to the case or the shaft itself. In other words, a new bearing would not fix that independently.

Doesn't sound like something I can't handle then. It really helps having the bearing numbers, too. I was looking at mine and the number was pretty well gone with a little bit of rust.

The races were still set to the axle and casing, but the ball bearings were really loose. I just use the tractor for mowing and light work, but I was concerned about that side giving out in the field.

Now I can get the bearing at Standard bearing and take it apart on the weekend. I had gone ahead a put it back together to move the tractor.

I'm really glad I checked here first, though. It'll make it a lot easier.

Thanks again to everyone, Bob

Hi Bob. One word of caution about discount or after market bearings, they aren't all created equal. Compare the number and size of balls in a ball bearing to make your choice. Less expensive bearings are usually that for a reason. When I rebuilt my M's rear frame last year I found that out. The cheap bearings have less load capacity due to fewer balls. For a outer axle bearing I'd go with a very good quality bearing. I bought all mine at the CNH dealer( because it was more convenient )except for two differential bearings. I got those very cheap at a discount house about 25 miles away and I worry about them to this day because they had about 8 fewer balls in them compared to the oem bearing. Good Luck! ...Randy

The heavier bearing goes on the inside end of the axle.

When the 560 bearings were updated the inner heavy duty ball bearing was replaced by a roller bearing and the outer standard ball bearing was replaced by a heavy duty bearing, the same bearing that was previously used in the inner end of the axle.
