vagmag Posted July 18, 2007 Posted July 18, 2007 I want to buy from Quaife the LSD diff. My car is 1.6 Sigma Ford engine and is beeing built from Westfield now. What type -from the huge catalog of Quaife- should I order?? I am confused... http://www.quaife.co.uk/FORD-ATB-DIFFERENTIAL here are the diffs. Which one fits for me? Thank you in advance... Quote
vagmag Posted July 19, 2007 Author Posted July 19, 2007 You mean that this http://www.quaife.co.uk/Ford-Sierra-7-ATB-differential and this http://www.quaife.co.uk/Land-Rover-Freelander-ATB-differential are the same , and I can buy either the first or the second? Why do these 2 have different prices? Quote
peterg Posted July 19, 2007 Posted July 19, 2007 No, they're not the same, it depends on which diff your car will be fitted with - ask Westfield what your car will have (it's probably the Freelander one but check before you buy one) Quote
vagmag Posted July 19, 2007 Author Posted July 19, 2007 Westfield says it is a ford Type-B unit. What does this mean? What to choose? I would apreciate your help because I cannot speak so well english to find out from Westfield and Quiafe... Thank you in advance... Best regards form Greece... Vagelis Could someone just make 2 calls -Westfied and quiafe- to help? Quote
stu999 Posted July 19, 2007 Posted July 19, 2007 QUOTE Westfield says it is a ford Type-B unit. That is what you need to ask Quaife for then - a Ford Sierra type-B LSD Quote

That is what you need to ask Quaife for then - a Ford Sierra type-B LSD Quiafe respond that it is propably http://www.quaife.co.uk/Ford-Sierra-7-ATB-differential .... but they proposed me to ask again Westfield... I cannot find out... Quote
andy jacques Posted July 26, 2007 Posted July 26, 2007 Talk to Westfield ,they will tell you wich is the best diff to have, they will probably get it and fit it for you as well before you take delivery. at an extra cost i would expect. This will save a lot of problems later Quote
Chasmon Posted July 28, 2007 Posted July 28, 2007 It is the Sierra one you mention (Sierra Type B 7") differential as fitted to all current car engine westfields. The Bike engine ones use the freelander diff. Westfield do the Sierra LSD one as a factory option though... But this would be a Viscous unit not a ATB. C Quote
cast iron Posted August 2, 2007 Posted August 2, 2007 Type B is the common Sierra diff fitted to loads of cars. Quaffe were f-in useless (similar to Tran X) when I asked them a similar question (I have a type A) Dont bother with Quaffe - speak to Phil at road and race. Spoke to him and said type A and he responded with a very great knowledge and understanding, was like a breath of fresh air. PS bet you love the motor Quote
chappers Posted August 2, 2007 Posted August 2, 2007 Seconded thumbs up for Phil at Road and Race Transmissions - Dropped off my 7.5" type B diff on Sunday night at his home and picked it up Monday night at his home. That's what you call customer service. The diff is noticeably heavier with the Quaife ATB installed compared to an open diff. Needed some help getting it back into the car. As stated you simply need to know whether it is 7 inch or 7.5 inch diff (almost certainly a 7" one I would bet), and what type, i.e. Ford Sierra type B, i.e. it has Lobro CV joints and not push in drive shafts. I guess you would need the one mentioned here. Must be easier though to just ask Westfield to get a Quaife ATB installed before you get it, and pay the extra £650 or whatever. Quote
Paul S Posted August 2, 2007 Posted August 2, 2007 If it's a 7" diff, the Quaife part numbers are: With lobro driveshafts: QDF15ZFL With push-in driveshafts: QDF15Z The "FL" in the first part number indicates that it has the Quaife "special" output shafts. They must be made from unobtanium given the price of them! The alternative (to save £200+) is to buy the QDF15Z unit and modify a pair of scrapyard output shafts. Quote
markboyce Posted August 2, 2007 Posted August 2, 2007 Post the pics of the modifying process Paul.. Best way of cutting cir-clip grooves Ive seen yet Quote
Paul S Posted August 2, 2007 Posted August 2, 2007 Post the pics of the modifying process Paul.. Best way of cutting cir-clip grooves Ive seen yet Okey dokey. This is the method for shortening the shafts, and cutting the circlip groove. It turns out that the splined part of these shafts are case hardened, which royally f*cks even carbide cutters, hence the use of a cutting disk - luckily the disk cuts a groove the same width as is required for the circlip. This is a before and after shot showing the shortened shaft with new circlip groove alongside the standard (nearside) item. The rebuilt diff awaiting its rear cover and installation in the car Just for good measure, this is a pic of the innards of the skanky viscous jobby that the ATB replaced. The seal(s) had gone allowing the viscous fluid to escape, and decidedly non-viscous 75w90 to get in. Building the ATB unit into its new home is quite simple, and requires nothing more than a spring balance, some string and a ruler. So far the new diff has survived a very wet and sideways trip to Le Mans, so I'm declaring this bodge a success. Cheers Paul Quote
