I'm struggling with how that all spins. It looks like either side will turn in opposite direction, but are linked together?

Be careful if you're going to undo the diff housing to get to the No-spin. It'll spring apart and hurt you. You need to clamp it together with something like a threaded bar with washers and nuts, pushed through and clamped tight, before you undo the two halves of the housing.

Witchcraft is all I can say!
Quite right Wizard, it's bloody frustrating this not being able to turn the assembly lark, I was going to use a bit of M8 bar and some nuts to slowly back it off and release it. Unfortunately the very last bolt is right at the bottom and I can't access it for love nor money frown

Had the day off work today so in between other jobs had a look at the Stalwart. In the end it turns out the clamps turned on their own and weren't splined to the inner shaft! With these knocked round and separated it then leaves the drive sleeve linking bevel box to transfer box free to pull back. Or in theory at least!
This is what it should look like in there!

This is the other side of that, the transfer box side of the bevel box, the drive sleeve poking out.

The internal spline of the sleeve then meets the splined shaft out of the transfer box.


So. These are what the ones on the truck look like biggrin

I tried for hours to get them to pull back into the bevel box, but no joy! I'm thinking possibly fill it with diesel for a while and then see how I get on after it's been left to soak

I've heard that a 50/50 mix of acetone and ATF is a really good penetrant, not tried it myself though.

Just tried that idea Dave and instead it all just pissed out the back and over the hull floor biggrin should have seen that one coming. On to plan Z

Haha, bit too penetrative, I guess!

Hurrah! Success of sorts. Tried a crowbar in there and pushed with feet and bang! Not the skinned ankle I expected, just a broken lug off the spline. Wait a minute... That's a tiny gap. Chisel in there and much whacking and it's started to move at last. Dosed in lots of WD40 for the night as my torch battery died.

There is a very informative demonstration of how it all works in a YouTube video.

Have you got a link?

I'm assuming that the centre of that intermediate section has a selector of some kind to choose which direction is engaged.

I can't find it, it was something I watched a long time ago and that makes me think it may not have actually been Youtube of course now...

That's right the drive from the gearbox comes into the transfer box via that, the dog in the middle is for the forward and reverse, controlled by a small lever in the cab. Exactly the same setup on my Ferret too.

Thought this was a pretty good diagram at showing the inner layout of the whole vehicle

When you get to the hub end it's truly fantastic stuff, the gears are 'timed' and apparently if not lined up correctly will lock up after a few revolutions.

Ah, I suspected they used reduction hubs, but wasn't sure.

So does that transfer box arrangement mean you have all the forward speeds in reverse too?

Sorry for the lack of updates chaps, I've been working bloody hard on everything but the Stalwart so that when the time comes I can devote full attention to her. Got a few other projects pretty much finished mainly in the form of my horrid little Spartan kit car so hopefully I can get an MOT slapped on that before Christmas and get it sold so that it makes space in the shed to put the engine and gearbox from Stolly. Unfortunately my favourite friendly MOT man's boss has gone bust and they're no longer doing MOT tests so it'll have to go somewhere more 'proper' which could cause setbacks.. whistle
Since installing my two post ramp in the workshop we've kitted out the place a bit better with a press, pillar drill, new bench top, big refurbished vice, tool lockers, a beer fridge and finally a reclining leather sofa. It's funny how many new friends I've suddenly made as a result biggrin
As I'm feeling guilty I might head up there this evening and have a look at the last drive sleeve to remove as that's the final step needed to remove that arse of a transfer box. Fingers crossed.
