Rear axle housing repair : my feeback

[FlatheadTed]

Yeah Lawire I thought the same ,the problem is that with the limited space you have any bearing you use that supplies its own inner race restricts roller size , I liked this because the inner race is close to the axle but still need a inner ring ,I did have that feeling that it would not perform like Fords one .I used it because my hub race was pitted ,I have since removed it because I got a near new drum .after it was removed I checked it and found the outer shim sleeve had bunched up so a better idea would need to be found .I think it could work with the right lube ,but a trial run would be needed with regular monitoring Ted

Ted, have a look at my post on using the NU1010 roller bearings,You only have to machine the axle bearing diameter down a small amount,and bore and sleave the worn hub,
I did two ends for spares for the 33 and 34,the axle assy is all done and on the wall as a spare.

Ok Lawrie thanks, does that mean removing the axle housing for machining , Ted

[Lawrie]

Yes, but its no trouble,I made a mandrel to fit into the bore of the carrier bearing recess,then a large centre in the wheel bearing end,clock it up on the brake backing plate spigot.

Lawrie did you use one or 2 bearings ?

Two each side,I was concerned about their load carrying capacity but it was about if I remember right about 9tons per side.

Ok that takes care of the problem i had in mind...if the bearing isn´t long enough the axle will see some stress from drum being at an angle.

[FlatheadTed]

Lawrie its sound like a real good solution ,If you compare a front tapper roller specially the outer one it would be similar to the IKO ,in size if it worked it would save a lot of extra work .Ted

[Lawrie]

Ted ,some where I have the drawings of the bits I made and the bearing and seal part numbers
I,m sure I had sent them to some one on the barn

Here is a link to the thread that I commented on a few years ago, with instructions on how I did this mod. The bearings are much cheaper than the roller ones mentioned earlier in this post. Scroll down until you see my pictures.

Here is what meric42 posted 11-29-2010:

"In the first pic you can see the inner spacer held in place by the factory inner hub seal cir-clip and the two ball bearings between which is another spacer @ 1/2" wide. There is a third spacer identical to the inner spacer but fitted on the out side of the outer bearing. The second pic shows the inner seal cir-clip and the inner spacer and the third pic is a close-up of the inner/outer spacer."

"The width of the spacers is not particularly critical, the complete set-up should be sized to fill the space right out to the seal retaining clip grove. The inner hub seal is no longer required as sealed bearings are used and should require no further lubrication."

"Remember the bearings used are only a loose fit into the hub so a thin sleeve is required between the outside of the bearing and the inside of the hub. I have used loctite on mine to secure the bearings and prevent movement in the hub."

He doesn't list bearing size/numbers.

If you use ball bearings,what do you do for axial movement of the axle?

Lawrie, I remember being very interested in your bearing conversion at the time you were posting details on this. It's possible that you sent me pictures and other details on this, but I can't remember now. I would need to go back into my computer files and take a look.

[cas3]

the way Lawrie did it sure seems like a good plan to me. retail price of those bearings is quite high, but i found some much cheaper shopping around on line. one on ebay at half price, but you need four. i like it, but i have not done it.

[FlatheadTed]

As I see it the axle side thrust is controlled by the spider gears ,Ted

Ted there is a small amount of axial movement in the axle,so you have to make provision for that,I saw some ball bearings that some A guys used,they had the rubber seals melted.they must rely on the bearing inner maybe just a slip fit on the inner bearing area.
It worked but not the best.and the ball bearings load rating is a lot less than the roller bearings.
Lawrie

[flatheadmurre]

Not to easy to install a ballbearing or conical rollerbearing in this aplication either...you will have to press with load through the bearing...and will be a pain removing the drum later.
Some kind of a 2 piece drum and a set of conical bearings could make it a fullfloater axle.
I still find it easier to make sleeves and use the original style bearings...even if the supply of good ones is low.

[Lawrie]

Look at my old post on the mod I did,none of that drama,I used roller bearings with a removable inner race.
