Hi guys, trying to fit axles to housing but can only get as far as the first 'o' ring on the bearing. I've oiled seal, 'O' ring, diff housing. Turning axle as I hit it with soft hammer. Looks like it catches on 'O' ring. Here's some pics for you to study. <br />It may just need a BFH but before I resort to that and screwing up the 'o' ring thought I'd better check. Previous bearings only had one 'o' ring. Cheers. Marty.

It feels like the splines are supported but haven't reaches the female splines, turning the axles doesn't turn diff carrier or feel like they're close.
It's also a spongy feel when hitting axle hard with hard plastic mallet, I presume thats the o ring bouncing.

Trying to test fit without brakes so I can see what's going on.

Why are you running that setup?
I never had a leak with the stock gizmo's......
Sorry for the stupid question, i just dislike reinventing the wheel.
You sould probably try some smaller O rings though, the way thas going in is more like a seal, where the bearing would be supported by the O ring if it had enough clearnace to fit, bad idea......The O rings need to be smaller dia so they squish out when you fit it, or run those square O ring things.
Cheers.

Rubber grease around O-ring and a piece of 4x2 pine is usually needed, They do need a fair whack to get the O-rings seated, And rubber grease is your best friend when trying to squeeze it into tight area... Your axles should be sitting in splines & esp. without brake....

Remove the O rings and see if the axles go in easier will give you a better idea of what's going on.

Hi, just asked for new bearings to be fitted by shop. Didn't know they're all different. Took out oil seal, still no luck, took off first o ring and it goes into splines but sticks on last o ring. I can see it getting squished. Where would I get other size o rings?<br />Cheers. Marty
I will try rubber grease a big hammer with wood tomorrow.

O rings removed and it feels like nice interference fit.

Bearing supplies should have O-rings, try to get the square edge ones as may make for easier fitting... As Bomber said the axle tubes were never designed to have the rubber o-ring type of bearing fitted & used gasket seal instead, So can be a royal pain when changing over & esp. with some of the cheaper imported bearings etc...

Ah ok so you didnt do it intentionally as some gun modification, cool.
I'd leave the O rings off and put some 1206 around the retaining plate, but thats just me.
Cheers.

I would still be inclined to rubber grease the o-ring and get a large lump of wood along with the F.B.H. and a few whacks should see it seated correctly, The grease is to stop o-ring from rolling on bearing which cuts them in half, But nothing to loose, As Bomber said they can be sealed with silastic...

I will agree with above. Rubber grease is an essential part of any shed anyway, Autobarn sells PBR brand stuff which is invaluable when rebuilding brake parts (impossible without it)
And correct my typo whilst im going, 1207c, not 1206c, Threebond, best general purpose RTV on the market IMO.

Just scrap the inboard O ring. One O ring is sufficient, that's all the original bearings had.
Install the axles up to the O ring then slip the backing and retainer plates over the bolts, install the nuts and use the four mounting bolts to pull the axle all the way home. And get some rubber grease for the O rings.

Ok, couldn't wait. Rubber grease applied, last o ring on, bang with hammer, no good. Fit nuts and tighten up, thought I had it but on removal it had sheared the o ring. <br />I'll return to diff shop for their advice tomorrow. Thanks guys. <br />Really want to get the rear end under the car tomorrow. Marty

After shearing o ring I have a nice square one. Maybe do that to all of them. First o ring normal. Second sheared for reference.

I repeat, its against the laws of physics for the O ring as pictured (in the first grove) to fit where its suppposed to go.

^^^ Agree DJ. Seeing the cross sectional view of the O ring in the last pic it is too large for it's intended purpose

So the flat o rings are correct? Had similar problems with mine and tested my patience. .

No, the profile of the O rings is round not flat.

Talked to diff guys. They suggested no o rings and silicone outer edge of bearing. I check that with no o rings it was a tight fit. 
it was really frustrating trying to get it all together and gasket in place. Messy. All done now. 
as far as I know the o rings are only to stop water getting in, not oil getting out.

That's correct Martin, There's no oil past that inner seal, Bearings are sealed, "Frustrating" is only there to test us all, Great you got it sorted......

I need to do an axel bearing and seal change on my LX torana diff is banjo 6 cylinder going by brakes and drum size.
Repco supplied a wheel bearing kit 2769 same as this https://www.ebay.com...353.m1438.l2649
There is no rubber seals (Orings) on the bearing
Which says is compatiable with
LH;V8 Petrol 253 Red 4.2L;RWD Sedan;Rear LH,Rear RH 1974 Holden Torana LH Sedan 4.2 V8 RWD Petrol 4.2L 8cyl 138kW GMH 253 (Red) 4142cc 138kW (Petrol)
When I pulled the axle out it has a tapered Bearing it it ok to use the other one ?
thanks thomo
