Diff welded ?? :D

[Mike]

A lsd is just that, limited slip and as long as it hasn't been built 'tight' you won't know it's there under normal driving conditions.

I know what and how an LSD works
I've just never had one or been in a vehicle with one.....

I've been in quite a few diff locked vehicles (either welded or switchable) though....

one thing I have noticed, is the longer the wheelbase, the less aggressive the locked diff tends to be.....


as for the LSD, I'm presuming the transit LSD is a clutch type?
not an ATB gear LSD?


for the record, concerning a locked rear diff, the SWB Mk5 transit has a wheelbase of ~111 inches....
the recommended minimum wheelbase quoted by Detroit for their automatic unlocking diff (not an LSD, its a locked diff unless it needs to unlock on hard surfaces) for safe and comfortable road use, is 100 inches....

they work by friction of the wheel on the road causing the internal diff lock to 'unlock' allowing the wheels to rotate at different speeds.
on vehicles with shorter wheelbases, they can cause unsettled manners in the corners....

could you fit a hydraulic handbrake ? like i "tried" spinning up the back wheels other day on the gravel but footing the break clutch and throttle is pretty hard for a 1st (rwd) timer
but for abit of drifting the handbrake must help

[newquay123]

wtf is that ? spam

Evening
You people are talking drivel...................................
'Clutch type LSD' they went out with THE Ark, they were too bloody dangerous,especially on Mini's (classic not Beemer), used to rip the wheel out of your hands.
'Limited slip and as long as it hasn't been built tight', ? the slip is limited by the fluid, like a torque converter, the liquid doesn't get 'tight'.
'Could you fit a hydraulic handbrake ?', What for ?, you are trying to get grip not go sideways.
You use AN hydraulic handbrake, because it responds quicker & is more effective than a cable handbrake.
'But footing the break (I guess you mean brake),clutch & throttle is pretty hard' , Why are you using the clutch ? have you never heard/learnt about 'heel & toe-ing', .
Drifting has absolutely nothing to do with brakes, foot or hand.

'Limited slip and as long as it hasn't been built tight', ? the slip is limited by the fluid, like a torque converter, the liquid doesn't get 'tight'.

Your right, the fluid has nothing to do with it its how many friction plates there are and the strength of the springs that push the plates together that can affect how tight it is.

The ford slds fitted to transits are plate type. Its the type that was fitted to my van at North Weald last year and I have never had the wheel snatched from my hand! Quaife also made some diffs which are the locking type

Hi Matt
The 'clutch type' went out many moons ago, I concede there are 'multiplate types' used.
The 'wheel snatched from my/your hand' applied to Front Wheel Drive (I did state Mini's), the point I was (simplisticly) putting over was the lack of predictability (inconsequential with RWD) but significant with FWD,which led to 'fluid' type LSD's.
Nothing else in my post 'contentious' ?
Have fun
Terry

[MinorMatt]

As far as I know there are no fluid/viscous LSD avaliable for transits

'Limited slip and as long as it hasn't been built tight'

- I believe he would be talking about a plate type which can be built tight!

I guess I can see that the clutch type in a classic mini could be a problem

But about brakes etc I agree with

Not directed at you Terry, but you arn't allowed a hydraulic handbrake as the sole handbrake on the road in this country - i am not sure if you are allowed to have a hydraulic AND mechanical

[Terry]

Hi Matt
I must admit I have no idea what/which LSD's are available for a Transit.
I agree hydraulic handbrakes are not a 'roadable/legal' option, but the implication in the post was not to create handbrake turns (for which they are admirable) but to reduce wheelspin,in which case 'fiddle' brakes would be appropriate (again not road legal).
(I realise none of this is 'personal', it just gets my goat to see drivel posted)
Meanwhile have fun
Terry

[IgorVigor]

Firstly Terry, I don't want to cause an argument.
I am presuming the 'clutch type of LSD that hasn't been used for a long time' that ypu are referring to is the fixed output clutch type?
Not the newer torque/speed actuated LSD's?

However clutch and cone type LSD's (which I believe is the type fitted to transits) are still widely used.......infact the main aftermarket LSD types are the clutch cone type and the helical gear type LSD (also known as ATB diffs)

the clutch cone LSDs used a ramped cam and a stack of thin clutch plates.
The cam can have various profiles to alter the characteristics.

Mine has been welded nw and can say it's great. Wasn't going to use it for slow drifting but it's more controlable than my e36 touring

I had a zf lsd from Ford in my mk3 camper it made a hell of a difference used van on car rally's I got in a lot of places I never got to without it but did not always get out after stopping maybe Ford surply them with a low preload I know when they use a lsd in rally cars they are set up with not a lot of slip
