The Triumph Dolomite Club - Discussion Forum

Is any body interested in buying a new remanufactured plate type LSD for the dolomite sprint, a mirror image of the original one.
I have spoken a few times to a very well known diff, halfshaft manufacturer that said anything is doable but here is the catch, it would reqiure a small batch run of 10 to 20 to be financially viable, plus we need to borrow one which is either new or in very good condition or manufacturing drawings to start from fresh, to enable them to remanufacture it. If I or somebody in the club can get hold of one to use as a master and enough people put there names forward and a sum of cash to show there level of commitment then it could be done.
I m sure that this project would be very benificial to many people now and in the future, something else to consider is that if it is manufactured successfully then it can keep on being made in the future.

Its up to you chaps now, this will either be an instant flop or will grow into something good for each and everyone, the club and future dolly owners.

Please reply to the thread with your thoughts and views

Stupid or opinionated replies not welcome.

mr flamer ,
i feel this will be hard to do , as the amount of people interested will be minimul.
i think the sprint spares option is the wAY TO GO , IF WE GET TWO ORDERS IT MAY BE THE WAY TO GO, POSTAGE WILL BE CHEAPER, MAY BE!

They are already being made. £795 plus VAT. Send me your orders. Dont all rush at once. By the time you have bought bearings & paid to have the diff built you will not get much change out of £1500.

tell me more dolly racer, or can you pm me a contact number for yourself.

ken, did you replace the one you blew up at mallory ?

I don't want to be a no all on this subject, but I don't think anyone would want to quote on making a Salisbury type LSD without looking at one in pieces and understand how they work.

Several years ago now we made a batch of plate clutch LSD, similar to the original units. A second batch was made to satisfy demand. The company that made them was a "very" specialised business making all sorts of high end automotive components. There are many parts within the diff unit, apart from all the gear cutting etc, with even special tooling made to make the LSD clutch plates.

We regularly get enquires for more LSD's, but unfortunately the "company" that made these LSD for us are reluctant to make more because they were loosing money due to all the machining issues that were not understood when production started.

We were selling the LSD for less than the UK units. If you are genuinely interested and can guarantee a reasonable quantity we can attempt to have another batch produced, but no promises. Our design and product quality is a known and proven under both road and race applications.

The problem will be compiling a list of interested parties and squeezing money out of them on a promise of them being made, also the postage and customs charge will be expensive, and what sort of time frame are we talking.
Might be easier to go for a ford atlas axle with LSD, have it sized correctly, bracketry welded on, job done.

Your comments are the problems that we face with every item that we have or think about having made. How many people really want the part, how much are they prepared to pay and how long will it take?

Personally I think that it is all to hard to do. Time is VERY hard to estimate, but from previous experience minimum of 6 months, but probably longer.

I would consider going the Atlas conversion. We have considered a similar type of product for our local market. Modified rear axle housing from another vehicle, choice of diff ratios and possibly disc brakes for around the same cost of a new Power Lok type LSD.

Here in the UK you can have a ford atles axle shortened with brand new tubing, blasted and painted, shot peened and uprated half shafts, lsd, choice of ratios, dolomite bracketry welded on, a rear disk conversion using a solid disk with a cosworth caliper incorporating handbrake mechanism, new bearing kit, assembly. approx £1700.
Although this is a lot of cash the parts used are all old ford and there are plenty of them about, and plenty of people specialising in axle preperation due to the growing interest in tarmac rallying, group 4 etc etc.

A rough costing to do a similar conversion using local parts, (most being second hand, except bearings) using a "cone type" LSD would be around $1800-$2000, ie about half the UK cost.

There are probable even 2 other options,  Quaife  and a Salisbury type.
Some time ago Quaife  was willing to make the TR6 type (fits the Sprint axle) in a batch of 10 and up.
The same week we found out that Moss still had 2 brand new TR6 Quaife LSD's in stock so we bought them immediately.

Last year we visit the professional MotorSport World Expo in Cologne Germany, trade only, and discussed this with a British company who had NEW Salisbury type LSD on display, for several type of axles British and foreign made.
They where willing to quote also from 10 of.
Because I'm a bit back on my feet again, we go in November to this show 6-8 November  again, and will have a look if they are still there.
An other interesting products they made where singro rings, proper made they claim, and half shafts, massive and gun drilled (did look good)

But as mentioned already by others, finding the REAL interested people, who put the money on the table is the hard part we found out when we organised a kind of group buy for ARP head studs.
In the end the batch was simply to small, ARP was not interested anymore at that time.
So we had then 10 sets made together with our friend Bunkes (the German guy who runs the green group H racing Sprint with the massive wing) by the company who made a lot of fasteners for Mclaren, expensive but very good.

By the way,
"Stupid or opinionated replies not welcome" is this mentioned in the rules of this forum?

seriously ken, may discuss this with you at some point...

(when funds allow)

Chris Witor, the Triumph 2000 specialist, advertises "Limited slip diff unit, (to install in your axle casing), Quaife torque sensing, geartype........£640" to fit 2000s and 2.5s. Is this suitable for Dolomite Sprint differentials?

When My brother bought his a couple of months ago Chris was out of stock and he said go to quaife which he did and two days days later it was on the doorstep.

The difference between the several axle housings starting from the TR 3 and up, the big saloons and the Sprint, don't know about the TR2, is the collapsible spacer,and the related main nut, with or without a split pin.
If Chris can deliver means that Quaiffe made them again, good news.

Putting it together need some skill a set of shims, a good spreader, a measuring clock and at least the so called Prussian blue. to see the contact pattern of the teeth.
It is very easy to end with a very noisy rear axle, or worse.

If someone has the ORIGINAL tool made by Cooper, to measure, and set up the pinion height, described in the manual, I would be VERY!!! interested to see some detailed pictures.
In the past we where allowed to copy such a set of tools from a former dealer, but 1 part was missing.
