In fact the late 1950 and very early 1951 80" had the yellow button but retained the freewheel unit constant 4 wheel drive.

A little confusing if you are used to the later system and don't understand the only "in reverse" thing of the early system.

With the frequency of breakage of Rover axle halfshafts in high range, I'm not sure that I would want to go 2 wheel drive in low range.

For those that are interested, the series forward control and 1 ton transfer case had a helical low gearset in constant mesh, so you could change from high to low or low to high without stopping.

unless its a SWB hes talking about its got a sals.. if hes got the original box in it low 2 shouldnt be a problem he'll run out of power,traction or gearbox strength before he breaks the sals.

(of course repeated abuse will break anything so if he drives like a drift queen then all bets are off)

I thought that was what I was saying when I said Rover axles.

To be more clear next time, perhaps I should state "With the frequency of breakage of the axle halfshafts, in vehicles with Rover differentials fitted to the rear, when in high range"!

my bad, Ive gotten used to some of the guys at work calling all landies Rovers (even range rovers) and refering to me as "The rover nut"

Interesting. I will have to look out for one of these vehicles.

Why shouldn't you be able to do this with the straight cut gears of the common transfer case? My SIIA currently has no first gear (and consequently no reverse gear). I start in second low, then change to second high. When downchanging to go up a steep hill, I then change back down to low while still moving. It is just another crash gear. It never crunches, as I get the revolutions correct.
