I am rebuilding the steering on my H. The bearing that was in it was apart, missing felt, cup was half gone, etc.

I have posted a couple pictures and want to make sure I am putting back together as it should be and its a little difficult to see by the diagram.

Am I putting the bushing (#44a) back properly? I am putting the cupped side against the cupped side of the shaft, leaving the flat side against the bearing as seen in pic.

The new truss bearing (#44) seems to be at a slight angle. Which side goes against the bushing (44a)?

and last - does the felt and felt retainer go on top of the truss bearing?

Any help is greatly appreciated

I want to help, but my numbering system and terminmology is different. Andit"s been a few years. My old parts manual is different. But if IF IF I remember right, from a few years, I had the same question. Looking at it, it finally seemed it was evident to me which way the bearing went. I THINK I remember the curved edge, where your finger points, sits in a corresponding curved area. It was then self-evident to me how the heavy load was transmitted from one face of the bearing, through the bearing, to the other face. I remember thinking it all made for a good design. It all made sense, to me. Not much help, sorry.
 
Felt retainer and felt goes in first. Bearing goes with the smallest ID race down or to the spacer. Hard to see the difference in ID size of the lower and upper race of the bearing sometimes without measuring. If I remember correct that's also the smallest OD of the bearing shield also.
 
The side of the thrust bearing that has the shell over the top of it goes into the housing next to the felt. The lower side, which is showing in your picture, goes against the spacer washer on the shaft. The lower race turns inside the shell. The upper race has the shell over the top of it. When installed in this manner the shell does not have to turn inside the bolster.
 
Looks like 2 answers so I looked this up. Unless IH made a change this was the recommended way. Think that ends up putting the side showing in the picture up. That's how I find most of them installed anyway.

The bearing in the drawing is different than the ones I am familiar with. The shield does not cover the top race on that one. It really doesn't show which race the shield is attached to. The grease will be coming up from the bottom so it has to travel between the lower race and the shield. The larger ID of the top race would allow the greased to be pushed out the top. My guess it that the way I described earlier still leave the larger ID race on top. With that style bearing the shield is pinched between the upper race and the casting so the grease still has to enter between the shield and the lower race, go past the balls, and exit the top. If the grease enters from the top like on a wide front the principle is still the same, the grease just goes in the opposite direction through the bearing.

When dealing with thrust bearings where the shield covers one race it make no sense to lift the axle before greasing. If you take the pressure off the trust bearing the grease is allowed to bypass the bearing rather than being forced through it.
 
should I grease the daylights out of the everything (except felt) as I put it back or wait and grease thru the zirt at the front of the bolster?
 
Grease everything as you assemble it. There is no guaranty that some of the grease from the zerk will actually go up rather than all of it exiting through the bottom.
 
Bearing 354676R91 has the cover retained to the end showing in the posters picture. Race on the small OD end extends past the cover slightly and will turn without the cover or the other race turning. Be nice if the poster pictured the other side of the bearing to see if its like that.
Agree that the bearing is lucky to see any grease after installation.
 
Thank you all for the help and advice. I am going to put back together this weekend.

D Slater - where did you get that book? I don't think I have ever seen one like it?
 
That's a IH service bulletin. Looks like the reason they made it was because of complaints of premature bearing failure and increased steering effort when installed other than recommended.
Is the bearing you have like the picture at the small OD end of the shell? Should be able to hold the shell and turn the race looking up in the picture and the race on the other end won't turn unless the shell turns with it.
Bearing will get some grease in the tractor, but usually takes over greasing to do it. Good bit of grease may come out the bottom of the bushing before forced into the bearing.

Is that an old service bulletin or new repro? It looks like its an old one. Can you buy that anywhere?

I will look at bearing tonight when I get home. I bought it at CASE IH locally.
 
my new bearing is exactly like the one posted by D Slater. So does the top of the bearing in picture get installed 1st or against the washer? or does it get installed just like the picture?
 
Side showing in my picture goes down or to the spacer washer on the shaft. Also the side that the bearing race will turn when holding the cover from turning goes down or the end shown in my picture. If you have a caliper the race with a ID .030 or .040 or so smaller or the end I show in picture goes down to spacer. End that the cover doesn't have the bulge on the OD goes down to spacer.
Side showing in your picture is the top side going up into the bolster.
Hope that's clear enough what my opinion is.
 
I know this post is from couple years ago, only 1 I could find about this bearing. Have read, reread which the bearing goes. Still not 100% sure which way. So I took pictures today, which is correct way, picture 1 or picture 2. Thanks
 
Never mind, figure it out. Picture # 1, smallest inside diameter goes down. Or easiest would be, writing is right side up.
