Defender 90 - High and Low gears

8 posts in this topic

I have an ex-MOD Defender 90 and having real difficulty with the High and Low gears........to the extent that i can't tell which one i am in or more worryingly when i put it in Low (or what i think is Low), i can then no engage the normal gears, so can't basically go anywhere.....

any suggestion welcome

Thanks

Check the lever is operating correctly first - remove the transmission tunnel cover and when you can see the drivers side of the gearbox, move the hi-low lever forward and back and check the operating rods are moving and pivoting correctly, and the selector shaft into the transfer box is moving nicely.

thanks for this......to engage High and Low should you just push forward and pull back, or do you need to move to left and the up and back across?

Back = high (normal) ratio
Middle = Neutral
Forward = low ratio

Right = centre differential working
Left = centre differential locked

Right / back = normal road driving
Left / back = use to overcome loss of traction on the flat (e.g. on wet grass), wheel changing.
Left / forward = climbing hills on low traction surfaces (off roading)
Right / forward = low speed maneuvering (with very large trailers etc.)
Anything / Middle = using centre PTO, confusing car thieves.

Thanks for this info.....

It would appear that most people are saying drive it in High (right/ back) - is this the case or should it be in neutral?

Does driving it in High not affect fuel consumption?

Hi, what do you mean using centre PTO?

You aint got one so ignore it :lol:

The leaving the transfer box in the middle(Neutral) to confuse thieves still is, but dont forget to engage before you drive away or you won't be going anywhere fast !!!

I would have gander online and download a user manual and have a read if I was you, lots of info in there ;)

High = high speed = road

Low = low speed, basically puts a "divide-by-3" on the back of your gearbox, you would know if you were in low because you wouldn't get much above 30mph, even in 5th

Oh and DO NOT drive in difflock on hard (tarmac/concrete/road) surfaces as you will break it.

The 4x4 system has been explained at length numerous times, a bit of searching on the forum or googling or reading the user manual / RAVE manual should clear it up.
