Re: Save a Moggy? Can a newcomer do it

In my view, anything is possible if you have the time, the money, and are willing to learn. Go ahead, try, but be patient, be willing to take advice and learn from your mistakes, and above all, be prepared for a lighter wallet!

Re: Axle tramp

Bear in mid that the restraint of the bearing is designed such that a seize bearing will spin in the hub rather than the axle housing. The nut needs to clamp much tighter than the halfshaft flange against the out race. The outer race has better leverage so its clamping should be rather light. It's ...

Re: Axle tramp

Is bearing lock a bit like thread lock? Does it still allow the bearing to be removed in future?

Re: Axle tramp

Question on installing bearings in hubs-do they need to be hydraulically pressed in? I did it using a vice and the outside of an old bearing off the Micra, which was a good fit for the outer race of the Minor bearing. I pressed it home to the required depth, as in the BMC manual, and used a gasket &...

Re: Axle tramp

Ok, seems like I may have a faulty hub after all. I took to half shafts out, in preparation for removing the diff, and found that the drum screws and half shaft screws were a bit loose. I also found that the hub is loose on the bearing. It's the same both sides-there is a couple of mm play in the h...

Re: Axle tramp

Well, that's what I thought, but all the wheels do it pull the hub tight against the half shaft. They don't actually prevent play, as far as I can see. Should the bearings be tight in the hubs, and not able to move back and forth in them? I guess it's worth sorting the hubs out first before messing ...

Re: Differential overhaul

:lol: :lol:

Hopefully not too epic. I think at least one pinion need replacing, but apart from that I'm hoping it'll just be a good clean, and the oil seal that needs replacing.

Differential overhaul

As I'm going to strip and overhaul my spare 3.9:1 diff, which is going to replace my worn 4.22:1 diff, I thought I'd start a thread for it. You never know, someone else might find my learning journey useful at some point. I'm sure someone will have posted similar before, but there's no harm in addin...

Re: Diff Identification

As I'm now going to overhaul my 3.9:1 diff and fit it in place of the 4.22:1, I'm going to start a new thread covering the process, rather than clog this one up.

Thanks Phil. The manual kind of explains, but leaves tantalising gaps in knowledge!

Re: Diff Identification

OK, I’ve now watched the video on p1 all the way through. I have a couple more questions  1-If a solid spacer is fitted, instead of a crush washer, does the flange nut still need torqueing to 140lbft? Does the pre-load still need to be measured? 2-What if the pre-load is reached when the torque is ...

Re: Diff Identification

Ok thanks. I was under the impression that you have to reset the pre-load when replacing the oil seal. Do you have to reset the pre-load when replacing the differential bearings? Do you have to go through all the procedure detailed in the BMC workshop manual, involving the dual test indicator? Cheer...

Re: Diff Identification

Ok. Is there no way of telling without dismantling? And should I still test the pre-load as i torque it up, to make sure it doesn't exceed the current pre-load?

Re: Diff Identification

So.... Is the crush washer not automatically fitted?
What about the pre-load? The pinion moves under the weight of the angle alone-doesn't that mean the pre-load is too low?

Re: Diff Identification

Ok, here is my home made in-lb torque tester:- IMG_20190912_215905~2.jpg It's a bit Heath Robinson, but it should do. It's a piece of aluminium angle, with two holes drilled for the diff flange bolts. I have measured 12" from the diff centre of rotation, and a 1lb (or 454g if you prefer to use sensi...

Re: Axle tramp

Worn half shaft splines has occurred to me, and I'll have to remove them before I remove the diff anyway. I've had them out in the last year or two, and I don't remember them looking worn. I feel like I should replace the oil seal on the spare diff, as it's an unknown quantity, but maybe I'll put it...

Re: Diff Identification

I'm about to swap a 4.22:1 diff for a 3.9, as well. I've no idea whether the oil seal is good or not, but assuming I have to change it, and I use a new crush washer.....what if I reach the 11-13 in-lb setting before the nut is torqued to 140 ft-lb?

Re: Axle tramp

I think I know what I'm going to be doing on Saturday!

Can anyone tell me what size the retaining nut on the diff plane is, please? The large central one, not the cardan shaft bolts. I have to remove it because the metal dust shield is damaged and needs beating back into shape.

Cheers N
