Re: Rear hub gasket

Yes both gasket and O ring are normally fitted, not sure what you mean about the hub loading though.

Re: Rear hub gasket

You need to nip it up so the bearing inner race is good and tight against the shoulder on the axle tube.

Re: Differential overhaul

Phil

Just for future reference, would you clarify the significance of the ATA and BTA designations please.
I have not come across this before and would like to know how to recognise the difference when looking at spare diffs.

Thanks

Re: Differential overhaul

When you took the 4.22 apart was it evident where all the prop shaft free play was coming from shown in your original video ?
Was it purely due to the 2mm lateral movement of the planet wheels ?

Can you not build your 3.9 up using the good cage from the 4.22 ?

Re: Differential overhaul

Sorry I cannot help with dimensions, but as a machinist I would expect that job to end up quite expensive. Machining a concave surface is difficult enough without it being on the inside face and difficult to get at, as Phil mentioned earlier it will require some special tooling to do that, and they ...

Re: can this block be rebored ?

Those engine number tag rivets are almost impossible to remove intact, to get mine out I used a thin cutting disc in a Dremel to grind a screwdriver slot across them, they came out fairly easily with a big screwdriver.

Re: can this block be rebored ?

I know I will get shot down for making this statement but.......... If there are no plus sizes marked on the pistons, there is a very good chance it is still on standard bore, that is exactly the situation my spare engine was found in as well. Another "indicator" is whether the aluminium number plat...

Re: Rear hub gasket

Phil When I did mine I found all sorts of burrs and chisel marks etc where previous people had pried the flanges apart on the hub and halfshaft. I spent quite a bit of time with a very fine file ensuring the mating faces were nice and flat, and any holes were very slightly countersunk to remove any ...

Re: Axle tramp

Also pay attention to the correct way round for fitting the lip seal, it is easy to assemble it back to front and then you will end up oiling your brake shoes. You are trying to keep any back axle oil that makes its way along the half shafts on the inside of the hub assembly, so the open side of the...

Does anyone have a decent condition manifold to fit a 1098 engine from approx 1969, it is part N° 12A1141.

Re: Axle tramp

I have my doubts that your hub bearings have got anything to do with the play, after all they rotate by design, but yours were moving axially in the hubs, and that would not account for any rotational clearance. I think you have another undiscovered problem lurking in that diff. :( Please keep us in...

Re: Axle tramp

I'm still on the edge of my seat wanting to know where all that free play in your prop shaft was coming from.
Did you ever find out for sure what that was ?

Re: Coil? Or something else...

You could try eliminating the distributor from your tests, with the ignition switched on just dab a wire from earth onto the points connection on the coil and see if you get any spark from the king lead, the spark will occur as the wire is removed from the terminal which is simulating the points bei...

Re: Axle tramp

It's probably worth mentioning that one side is right hand and the other side is left hand threaded as well.
Not immediately obvious if you don't know about it.

Re: Axle tramp

The application of heat (blowlamp) usually destroys the loctite bond. I use it all the time when making parts in my model engineering workshop, it is very hand to be able to attach a temporary mandrel to a part to hold it whilst machining in a chuck or milling vice etc. Then once finished warm it up...

Re: Axle tramp

It looks to me from the video that the bearing outer races have been spinning in the hubs and have probably worn them over-size. If it were me I would be thinking about new bearings and some good second hand hubs, I had something similar on mine but nowhere near as bad as that. You have to get the e...

Re: Built in drip tray

If you make sure the crankcase is breathing correctly you should not need a drip tray. Mine was the same until I added a later breather set up, it is now "almost" leak free.

Re: Axle tramp

It might not be a problem with the mesh between pinion and crown-wheel, it could be other parts that are worn, half shaft splines for instance. To have that amount of movement between pinion and crown-wheel it would have to be almost out mesh altogether, or a tooth missing, I suspect it might be som...
