Tried Drivetrain but no joy.

Does anyone out there have any information or thoughts on the settings for the center diff on a 22B and the best positions for different conditions such as wet, dry and as it's that time of year ice.
Darren.

P.S: Asking for a friend who is thinking about buying one.

All the way back in the dry, one notch forward if you are a woos. One notch forward in the heavy rain and standing water.

On sheet ice with zero grip then full forward, but any grip and the diff will be buggered.

i dont see how diff settings are material to buying a 22B

Darren Thompson

Cheers Adam it was just a question I was asked and I said I knew were I could get the answer. The guy was not deciding on the purchase of the car due to the adjustable dirff he just wanted to know as I did what the script was with the settings.

If you have Zero Grip,


you have, eeerrrrrmm...

ZERO GRIP

SDB

be careful

hard and fast rules like that are potentially dangerous.

I am adjusting the diff regularly on a journey to suit the conditions (especially in the wet).

Do not take anyone's word for it. These things were designed for rallying, they are agressive and can bite. Driven with respect and care, they are wonderful cars. Just be careful.

All the best

I am trying to pass advice on not scare him LOL !!!

Cheers for the replies gents I am sure the gentlemen in question will be around these parts soon.

Why are you playing with the twiddly bits in the loose

Adam M

True zero grip is zero grip, btu I was exagerrating.

Thanks simon for pointing it out.

I drive always with it right back. All I know is if it feels a bit twitchy at the back, I notch it one forwards.

This is not supposed to be a hard and fast rule, just a "this is what I do". Should have made that clear.

I also think it would be stupid to drive on the road in such a way that the position of the diff should be the deciding factor in whether you make it round a bend or not.

RAver

Darren,
I have a type RA with the centre diff. which may or may not be the same as the one in the 22b??
I haven't experimented much as the weather has been kind so far (!) BUT:
The bottom two positions (off and the light above it) are OK it seems as far as road use goes, there is no wind-up of the diff.
I accidentally had the setting one higher than these (#2) recently and experienced a small amount of resistance to turning sharply -as when parking. You can feel it through the steering wheel.
God knows when you can use these higher settings -they are pretty much for very loose conditions I should think ie snow/gravel/ice?
Probably the top one is useful if you are stuck in deep mud? Just keep the steering straight!!
It's a pub natter type device.

Adam M

If the wheels are slipping, there is no harm i having the diff fully locked, regardless of whether the steering wheel is turned.

The diff makes an objection noise because the front and rear axles are trying to turn at different speeds because the radii of the circles they are truning through are different requiring them to travel different distances in the same time. This speed differential is only due to being connected with the road. If sluipping then there is no speed differential.
