U800/U900/U1100 gear levers
« on: February 17, 2013, 02:08:48 pm »
for models U800(L), U900, U1100(L)(T)




A) Main gear lever
- 6 speed
- 2 working gears, 4 road gears



1 & 2 are usually only used in the fields and for reversing etc, 3,4,5 & 6 are the road gears.
Between the working gears and the road gears there is a gate that you need to tap the gear stick over to get to that set of gears.


B) Forward and reverse
- forward, neutral, and reverse

In order to get into reverse the main gear stick must be all the way over to the left (1st and 2nd area)
All the way forward is forward
middle is neutral
all the way back is reverse

c) Half gear splitter
- High, neutral, low

 Use on hills for a half gear.

All the way back = high
Middle = neutral
All the way forward = low

D) Cascade lever
Crawler gears



S= super crawler, very slow
C= crawler, slow
0= neutral
I= Intermediate, road position
E)2x4 4x4 diff locks

- all the way down = 2 wheel drive
- Half way up = 4 wheel drive with gear box diff lock
- all the way up = 4 wheel drive and front and rear axle diff locks

ATTENTION, some unimogs have different systems.
1) The detent: This is where the lever needs to be given a little tug upwards to engage 4x4 and again for diff locks, and a push down to do the opposite.
2) Push and lift: This is where the lever is pushed slightly to the right and then lifted up.
3) Twist knob:
twist all the way to the left = 2 wheel drive
One click to the right = 4 wheel drive
2 clicks to the right = 4 wheel drive and diff locks



F)PTO's

PTO (power take off) is used for running implements on the front and rear of the vehicle.

All the way back = rear PTO
Second from the back = neutral
Second from the front = front PTO
All the way forward = front and rear PTO's

G)High speed under belly PTO
Not on this gear box, so ive just labeled where it is.

Unknown how to operate this, but we do have one for our unimog (yet to be fitted) so will be updated at some point.

Any question, as usual, just ask. :)

Quick question.....

To use the splitter function, what position does the cascade gear lever (lever  D) have to be in?  I am assuming position "I"?

For general road use I use the cascade lever in position "O" which I have assumed to be off, and then lever C to be in the High position.  Is this a correct assumption?

Many thanks,

Nick

Lever D should be towards the rear of the cab to be in the higher gearing and forward for a reduced half gear. And yes position "I" which are road gears.

For road driving cascade gear lever It should be in "I" with splitter gear towards the rear of the cab.

Hi Boatboy, welcome to Unimog Club UK

it doesnt matter if the cascade lever (D) is in position I or 0 for road use, as it will still move as long as the splitter lever (C) is in the backwards position.
the only thing with having the lever in position 0, is that you can not use the splitter lever, so i tend to drive in position I, then i can use a half gear when struggling up a hill  :)

any more questions, just ask :)
