1978 Series 3
Non Overdrive
Cant get it into Low ratio
THe lever moves to High / Neatral fine, but just wont move to Low.
Ive tried it stationary and on the move ( slowly in 1st )
But nothing :(
Any ideas guys ?

This is going to sound daft but mine wouldn't budge form high (I was almost thinking it needed attention) until I pulled the stick very hard with the engine and gearbox warmed up , now its much easier and works fine!
PS Wat exactly does it say on the side of your truck, emergency fresh air, support unit ??? Can I sell fresh air, iv got loads on the farm?

Seazed selectors probubly. Is it in 4 or 2wd? Rock the front prop in all lever posituons to see if its "locked" or free. High range should be 2wd unless the yellow button is depressed (you'll need to select low range to deselect it though) and neutral should be perminant 4WD the same as low range (despite the fact the yellow button apears to work the same as it does in high range.
To unsease it you need to remove the black metal cap from the end of the front wheel drive houseing - its where the transfer lever goes into the box under the drivers floor (to be removed). From memory the yellow button pin needs removing too. From there you can plusgas the linkages and perswade them to start moving again. You might also find it usefull to remove the top coverplate closest to the transmission brake - from there you should be able to use something to push this rod out. Also by putting some light presure on the transfer leaver and tapping the box with a hammer might shock it loose a bit easyer - don't go too mad though.
Its a slightly complicated system with 3 rods and a rocker shaft, and some shafts are moved solely by springs. If things stick up it can do all sorts of funny things. Sadly if this doesn't cure it you'll need to take it apart as it might have been assembled wrong.
As a temp measure, if its stuck in 4WD and you want to use it on the road you can IF you unlock 1 Free wheel hub, don't unlock both! If you don't have FWH then you'll have to take a propshaft off.
This is a tipical problem for series landys that haven't had the transfer gears used resently, such as been standing or road only use. during normal use it shouldn't be a problem.
