I guess i'm thinking that the ird isn't robust enough and would break without the constant slipping of a vcu.
 
Series and Defenders are agricultural vehicles designed for farm work and military work. The freelander is an suv designed for shopping trips and leisurely drives in the countryside, you can't compare them.

A lot of people use there Freelander in mondo mode without any problems (apparently).

With a clutch system you would do the same as people who have there Freelander in mondo mode, but with the flick of a switch instead of hours of messing around.

Yes but I'm just questioning the bit about 4wd not 2wd. I think that you would still need a vcu in the drivetrain to protect the ird.

20 mins actually ;) :p

Although if you take Dazlanders approach, whereby the rear shaft is removed, tricky with the U- washer, a quick release split pin and castle nut would be handy.

Agreed, for the early ratio IRD's with 0.8% difference

The later type with same ratios front and back shouldn't be a problem

IRD ratios :confused: I thought only the final drive had an upgraded ratio, as far as I know the IRD has never changed. Or am I missing something?
 
wot exactly are yu saying? that the system in series, defenders and discos doesnt work, coz it has no vcu? They are all mechanical locks into 4wd.


I thought the difference between the Freelander & other Landies was that the rear wheels were geared to turn slower than the front on the Freelander with the VCU slipping to allow for this on the road, but on the Defenders etc. they were basically geared to turn at the same speed albeit through a centre diff to compensate for different grip levels between the axles, especially offroad. I could be wrong, but wouldn't like to mess around with mechanical or electrical locking of any kind. Should it fail in the locked position, would it not be like having a seized VCU?

Here's the ratios, judge for yourself

The IRD ratios changed in 2001-02,

Old IRD ratio - 1.458:1
New IRD ratio- 1.467:1 *(every Freelander from VIN YA999999)

Some of the early FL have different final drive ratios as well:

Petrol engine - 4.200:1
L-series eng - 3.647:1
Td4 engine - (manual) 3.182:1, (auto) 2.910:1


Some new ratios >2001:

IRD input shaft to IRD countershaft - 0.828:1
IRD countershaft to front driveshaft - 1.762:1
IRD countershaft to prop shaft - 0.553:1

IRD ratio > 2001

Td4 - 1.467:1
1.8 - 1.467:1
KV6 - 1.359:1
 
some iteresting ideas here, i think you would have to keep the viscus unit, an electric clutch would be just the job, cutting a prop is easy and cheep to have done,
the other way or course is to use a dif unit with a locker, this would give the best of both worlds, a stock dif without crown wheel ect could be recased and mounted in place of the vc, you would have 4x4 at all times but with none of the wind up that freelanders suffer with, in deep mud lock it up, for most people an un-lockable dif would be fine
 
there are lots of firm that will cut a prop, i have done it myself and its easy, better to have someone do it that can balance it
 
I was speaking to my brother in law (engineer and land rover crazy, in fact complete fanatic) who had the same idea as nongrokal. He said the simple way would be to use a dif unit with an air locker to get you out of trouble. I shall speak to him more about it seeing as though I am keen and he has good ideas.
Would this not void the insurance though?
He did say though that the VCU was a good idea in principle and it was introduced to mass market so that anyone could drive a land rover (freelander) out of sticky situations.
 
yes i think this may be the way to go, a land series rover dif without the crown wheel and pinoin is not that big, its avalible anywhere and locker kits are easy, a new case would have to be made, the outher way seems to be an electric clutch, these are avalible have yet to sus them out

What part of the 'diff' do you intend using??
 
i dont know yet, there must be a way to alow one shafts to turn at difering speeds using parts from a diff, will have a think, or any ideas please
