Rear axle housing repair : my feeback

[tof33]

Hello
Recently I bought a Ford 35 and during a rear brake inspection I showed the wheel bearing surface of the axle housings was scored on the under side between 0.02 to 0.11".
Usually you have to buy a new inner race and grind the shaft housing : quite hard, expensive and who can do that ??

So I think to an other method. Only 100 miles since but all is OK

I put a big IKO bearing on the hub (no grinding needed): ref: TR628138-IKO
I insert the bearing inner ring (LRT556238.5-IKO) with an other custom made inner ring and a lot of Loctite 638.

See pictures...

Keep us posted on how long it lasts! I'm sure back in the day people did much more questionable repairs to keep their cars on the road. If this holds up, it beats the hell out of disassembling the entire rear end, machining the ends of the bells and fitting new bearing races.

This is interesting...... need some details. What is involved in making a "custom made inner ring?"

Thanks

Tom

The custom made inner ring is very simple:

in diameter : depends your housing surface, but usually the original bearing surface
out diameter : the inner diameter of the IKO bearing : 55mm
length : the original bearing surface housing length

Precision:
- you need 2 IKO inner bearing : one for the bearing and a half for the seal.
- and another part to turn whick hold the seal (62X72X9 metric size : I'm a frenchy :-) )

About the cost : 120 Eur for bearing, ring and seal, 100Eur for truning custom ring and seal support + Loctite.
So a repair for 250 Eur.


I haven't take other picture because of time lack : I have to use the car for a meeting.

Welcome to the Fordbarn. I have often thought there must be some alternate ways to repair those rear bearings. Another member here....Lawrie... from Australia, was also looking into trying some alternate rear wheel bearings, but not sure how that turned out. Let us know how your idea works. Also, I /we would enjoy hearing some details on your 35 Cabriolet, assuming your avatar picture is the car you just bought and doing the bearing repair on.

Yes my Avatar is my 35 cabriolet. More exactly it's a page of the Kellner catalogue.
My car is a French made V8-48 with a Janer custom body (5 places under the hood). Janer was the coachwork for little series by Kellner.
I don't know any other same car. Today there's a Buick '34 with the same body for sale (http://www.prewarcar.com/classifieds/ad203678.html). Quite strange


And I'll give you rear axle "health" information ... I have many car it could take some years (2 or 3 ) to reach 1000 miles ...

Is the new bearing surface, (ring) heat treated for hardness?

[Lawrie]

John, my mod turned out great,I have not run it yet but its all done and on the wall as a spare,I may fit one side into my 33 some time as the axle end is a bit second hand..
let me know if you want some info.
tof33,if you do a search under ( rear wheel bearings ),you will come up with some pics of the mod I did.

Yes the inner ring surface is hardened. It's sold with the bearing.

Please be patient with me, I want to be sure I understand this. The custom ring's inner dimension fits the axel housing outer dimension and the custom ring's outer dimension fits the inside of the race that comes with the bearing. The bearing's outer dimension fits the inside of the hub. The seal needs a custom ring to make it fit everything. I get lost when you say you need two bearings. Your use of the word "half" gets me puzzled. Are you saying you fit two roller bearings side by side inside the hub, and two races over the custom ring on the axel housing side by side?

[Russ/40]

BTT looking for a confirmation from "tof33"

[tof33]

Yes you are right.


So from inner to outer:

1/ custom ring : 52,3 mm (axle housing) x 55 x 54mm (axle housing length)

take, check, verify your own measure, depends on you axle condition

2/ inner ring 55x62x38 + 55x62x16

"1 and a half" : you have to cut a 2nd inner brace to reach the 54mm. This second brace is needing for the seal

3/ bearing 62x81x38

only one. 38mm long vs 43mm fort the original bearing but it doesn't matter.

fitted in the hub: original hub size around 80.93mm (tight! ) but in the wear in the middle could extend to 81.2mm (on my car) and you need some fixing/sealing compound.
Note: if you heat (a little) the hub, it can be more easy.

4/ seal
you can find 62x81x8 seal but with wear I prefer do an "holder" for the seal to have perfect fittement


Hope it's clear: you can send private message if needed. (Sometimes I don't use the correct english word)

This may help. 1-1/2 of these per side.

And one of these per side.

Then you make a sleeve that goes over the axle to fit the bearing inner(s) and put the outer in the hub. You then need a seal or an adaptor for a seal.

Thanks for the info, tof33, that's pretty interesting.

Mart.

[Russ/40]

Thank you tof33 and you too mart. The photos of the items helped immensely. I did not realize the bearing was a caged bearing, stationery to the hub.

Hi, I've just come across this post and looking for a repair for my 40 pickup rear axle. Am I right in thinking the hubs of a '35 have a larger outer diameter bearing than a 1940?

I'd be interested to know if there is an off-the-shelf bearing and sleeve that could work. Or would it be an option to use '35 hubs/drums on a 40 diff?

[JM 35 Sedan]

Bttt

tof33, any updates on this rear bearing repair?

[FlatheadTed]

JM 35 asked for a update ,this is my slant on this upgrade ,The bearing I used is NA6911 ,IKO it will work for Model A through to 1936 ,in 37 the axl race was smaller so would need a different bearing ,The inner sleeve is a snug fit on the outer but a sleeve is needed , in the drum hub it needed a shim of about 1mm ,Ted
Foot note a Sleeve is still needed .

bbbbbbbbbbb

[Lawrie]

Ted I didn,t like the IKO bearing as I thought the little needle rollers would be turning too fast,and I didn,t know how they would go with grease not oil.

Hey all you 35-36 guys with a bad race: You don't need to do any machine work, just flip the housings side-for-side. The bad part of the race will now be on the top of the housing where there is no real pressure. The new bottom of the race is fresh and should last another 80 years.
