If you buy a new Foden 8 wheeler this ZF 12 speed stick is standard,BUT believe it or not all you do is put on the DAF CF gearknob 
and connect a couple of wires and “hey presto” you have a ZF 16 speed box!!! 
R 1-5/6 3 - 9/10
C 2 - 7/8 4 - 11/12
last time I drove one of these was on Foden 4335 8 wheeler m reg they don’t have two switches/levers for range change and splitter just one switch which has three positions in position 1 you get gears 1 2 3 & 4 in position 2 you get 5 7 9 & 11whilst in 5th move switch to position 3 without the clutch just slack off the throttle and it shifts to 6 do the opposite to go down, the one I drove was a crash box though and they count the crawler gear (opp reverse) to make it 13 speed no range change or split on that gear I found it easier not to use the clutch other than setting off or stopping

This has been a fascinating thread. It dredged up a long lost memory I have of when we first got those steel cab Dodges (the successor to the ‘Kew’ Dodge which shared the same cab with the Leyland Comets & Albions of the day) with the windows all around and the clattering V6 ■■■■■■■ (the first of the make to appear in the UK I think). They had a standard 6 speed box with a 2 speed rear axle like everything else in the mid weight range then but somehow it transpired that 5 high was higher than 6 low so you changed as normal through 1 to 4 high and low in sequence but after 5 low came 6 low then back to 5 high and finally directly through to 6 high.
By the way Bully my last Mack had 2 gear sticks with 4 in the main and 5 in the compound. Every single change had to be done at exactly the right revs and some required two hands with the steering wheel ‘secured’ in the crook of the elbow. Bet they’re outlawed now eh? 
Amazing how all you young blokes can drag an old geezer down memory lane 
Salut, David.
Hey David,
I never did drive one very much but my dad had one of those mickey mouse fodens with a similar setup, 4 on the stick & 3 on the dash. If I remember correctly, it was 4+4+4 rather than range & overdrive, so every gearchange meant moving the stick (& plenty of that with stunning 180 gardner power 
)
He then bought me a real up to date one … Ex Steetley 79 T reg 8 legger with the foden 12 speed in it

that sounds like a 13sp fuller to me m8. Daf 2800 & 3300 used to use them a lot. Not a bad box after a bit of practice

Now you’re talking, the Foden 12 speed. Have said it here before but I once restarted with an empty powder tank trailer on Swinscoe on snow with that box - merely by being able to choose exactly the right gear. Not too low , not too high. That was the first steel cab with a ■■■■■■■ 205 in it.

Eaton Twin Splitters are the best box ever made. Fully laden you can in theory travel from Dover to Birmingham without moving the stick. (traffic permitting)
That must have been a while ago Pat nowadays to travel form Dover to Birmingham you need to use every gear you have and thats just on the M25 wait until you get on the M1 and M6 then you have to use the crawler to kill the boredom and find out what speed it actually does when you arer stuck in ANOTHER jam.:).
I have never had the pleasure you guys mention of the Eaton twin splitter (a test drive once in a Foden put me off it) i have only ever driven trucks with synchromesh gearboxes or auto boxes but i still (when i do drive) rarely use the clutch apart (obviously) from pulling away.
It’s a 12-speed version of the American Eaton Fuller 13 speed. They limited it to 12 speeds because they needed to fit synchros, due to the fact you guys can’t shift crashboxes.

Don’t include us all in that. I always found the crashbox easier. Get the revs right and the clutch is redundant. Never had elbow or shoulder trouble until synchros arrived!

I think that the twin splitter in Foden was not the best installation. (Something to do with linkages) I have regularly driven one in an ERF E Series and it is an absolute joy to use. The gear lever travels like a knife through butter when you get the hang of it!
Fortunately i have never had to drive an ERF either, nor wouldi hopeto in the future.
