The plan is to get the machining (re-bore, head, cam, etc) done and assemble it myself.

We've just finished building a house so money is a bit tight at the moment, and more importantly I do like the process of assembling things and getting them working. I did a very mild standard rebuild on my old Mazda (just rings, bearings and gaskets) and it ran great until I sold it.

That should mean more photos for here, and many more questions too! It's not going to a be particularly quick build, but hopefully finished in the next year.. (Not that I have much to show for the last 10 months!)

I've got a hold of a 4 sync gearbox casing. It is missing a few bits so hopefully they'll all swap over from the rod change box. Were the diff covers the same for 3 and 4 sync gearboxes?

I believe they are the same Timmy.

Yep same, only S ones were much different (had 1/8 bigger bush & seal).
You can also use rodchange covers on remote boxes, but the LH one needs the pointy bit trimmed off its flange.

Sorry that wasn't too clear. I should have said diff housing, the alloy bit that holds in the diff.

I've got the diff side covers worked out

Yep, still the same. They are a matched set though (gear case & diff cover). Line bored i think.

I asked about changing the diff housing a while ago and the doc had a very helpful reply.

Hope this helps.

Yep, thanks for that. I remember reading something about it recently. Did you have any progress getting yours done with the pudding stirrer? I like the idea of that how it looks standard, but I've never driven one with the long stick so I don't know how nice it would be?

I guess you'd need an extra engine steady or two to keep it in check..

Danny_ has a 4 synchro remote/puddin' stirrer shift box in his Moke.
It feels very good, now, but I had to build up with silver solder the tin plate's socket where the ball sits then use the die grinder and a ball stone to resize it. Then packed with molygrease.
Before I did this it was like a stick in a bowl of spaghetti (worse than a worn Morris 850 shift).

Parts for the puddin' stirrer shift are rare now, and apart from John Smidt or `TheMiniMan', I don't know where you would find s/h parts.

I think I have one kicking about. The pudding stirrer and magic wand are different housings though, one is a socket into the diff housing, the other is a socket held captive by a retaining plate.

Then there's always the problem, second hand parts are just that, second hand :-/

Amazing what worn parts can be reclaimed by hardfacing, brazing & machining, or hard chrome plating.

I got as far as rebuilding the gearbox. I measured it all up and it all looks good. Within a couple of thou. Just waiting on some diff parts to complete the rebuild of that and I will then install it.

How do these look? Also, will the surface rust be a problem or not? Is there anything I should measure on the old boxes before I pull them to bits?



I've also added another three SU carbs to my collection. I should count them to see how many I have now..

No, still looking for a diff housing.. What gearbox is that one off, and is the shift rod seized up, or does it move/rotate?
