Please help......Working on a 240 utility and need fixed ASA

I am helping a friend work on a 240 utility and we discovered that the rear hubs wont tighten up on the splined axle shafts. It seems that there is nothing to prevent the hub from being slid onto the splines when the bolt is tightened up on the end of the axle. I walked around the local salvage yard today and did not find a similiar setup on any of the utilities that were there (no 240's). Can someone tell me what prevents the hub from sliding further on the axle shaft or better yet if someone could post a picture of one or has one near NE Wisconsin that I could come and look at. Thanks Brad
 
I peeked at the official Case IH parts page and maybe found what you are missing????? 351 246 R1 the rear wheel hub clamp?? NE Wisc. - anywhere near Black Creek Tractor? but I'm sure they wouldn't have a 240 any model.
 
I spent over an hour walking around the yard and inside the big sheds at Black Creek Tractor today. They had a 240 row crop in the yard and parts of a utility on the shelf in the shed. No luck finding the hubs though.
 
I understand you mean the hub will move back and
forth on the splined axle and has a large washer and
cap screw on the end of axle. If the movement is
only a small amount you may be missing the spacer
that goes on axle first. If it moves more than the
thickness of the spacer you must have mismatched
parts. Problem is I don't know how thick that spacer
is, maybe quarter inch or half inch. The hub has to
bottom so no movement is possible.

How much was left of the 240 row-crop?

Send me a PM, I might have a picture to send you of the outside of the hub.
 
As I recall, there should be a big internal snap ring in the hub, near the outer end. The 2 parts should press together with some very high force and stop when the snap ring contacts the axle. The flat washer and bolt should not have a lot to do to hold it together.

Sometimes the hub/axle joint loosens up. You usually find wear on both parts and it can't be fixed without changing out both parts. Sometimes you can remove the snap ring from the hub and push the hub in farther to tighten it up. You then need a sleeve over the axle for the washer to push against. This is usually a temporary "fix".
 
I think you know more about that model than I do. I
do see a snap ring listed in parts book but it does
not show it in picture.

Look at the left end of the axle shaft, part #16, that's the only snap ring. Holds the bearing on the inside end. Parts book only shows a washer and bolt on the outside end. Pretty hard to tell just looking at mine, can't see much.
 
Like I said, "as I recall". The last time I even saw one apart was in the 1960's. I think my description was essentially correct, even if there is no snap ring. Look at reference 9, part 369389R1. It is listed as ring, rear axle, hub retainer. It is not present on the Farmall 240. The position isn't where I would have expected, but it has to be in there somewhere. It isn't shown as a snap ring. Maybe it is a smooth ring that drops in against a shoulder.
 
The wheels on Dad's W400 are splined like that.

I can't remember if there was a lip on the hub that prevented them from sliding in or if they just rode against the inner race if the axle bearing...

What I do know is, they were LOOSE on the splines. Really bad loose. We ended up making full-wrap shims out of heavy roof flashing.
