When I put the unit inti Lo or hi ratio she will move...!
I have bled clutch, adjusted foot pedal. Still no movement... only in hi/ lo.
Much appreciated any help. Thank you
There are two neutrals, 1 in the main gearbox and 1 in the transfer box.
The main gearbox (R380 or LT177) drives an output shaft which typically spins faster than the engine in 5th, the same speed when in 4th and slower when in 1st 2nd and 3rd.
Drive to the output shaft is disengaged when in Neutral ie the output shaft doesn't spin at all when the engine is running.
The output shaft of the gearbox drives the input gear of the transfer box (LT230). This gear spins at the same speed as the output shaft of the main gearbox ie, slower than the engine in 1st, 2nd and 3rd, the same when in 4th and faster when in 5th.
The LT230 has two gears and a neutral High and Low.
In low the output (which drives the propshafts) is slower than the input by 3.32:1, so 3.32 turns of the grearbox output/transfer box input = 1 turn of the transfer box output which drives the propshafts, the axles/differentials and the wheels.
High ratio can be different ratios but the common gearing is 1:2 and 1.4:1 (there is also a 1.66:1 in some military vehicles).
The transfer box also has a Neutral where no drive is present on the output/propshaft flanges.
The reason for the Neutral in the transfer box is that there is a Power Take Off flange on the back of the case which is directly connected to the input flange which in turn is directlly connected to the output flange of the gearbox.
This PTO is commonly used to drive a hydraulic pump which commonly powers a winch - other 'tools' are available.
Obviously you don't want to move the car whilst using the winch (or other tool) so you select Neutral in the transfer box which removes drive to the axles/wheels.
Hope that expains things
