Noel Mclaughlin Posted February 1, 2002 Share Posted February 1, 2002 A friend of mine has an Escort Mk 1 fitted with a 2 litre engine producing around 190 hp. He has a Quaiffe lsd fitted to the axle but has problems with bolts coming loose on the crown wheel. Can anyone suggest a fix , or, another diff that has proven to be more trustworthy. Car is used for Historic Rally and occasional circuit. Link to comment Share on other sites More sharing options...
R2D2 Posted February 1, 2002 Share Posted February 1, 2002 I have about the same spec. in my RS2000 but I don't have a problem with bolts coming loose. I do use a Tran-x LSD but it shouldn't make any difference. Try new bolts and loctite it should be ok. It might be worth checking that everything is "square" before you torque it all up.

John Posted February 1, 2002 Share Posted February 1, 2002 This is a known problem with Quaiffe LSDs for the English diff. The bolt heads just contact on the diff casing causing them to undo. You will need to fettle the bolt heads slightly to eliminate it or dremmel the case slightly in the offending area. Speak to Phil Stewart at Road and Race Transmissions for more info. 01959 525105 John Link to comment Share on other sites More sharing options...
R2D2 Posted February 1, 2002 Share Posted February 1, 2002 Glad I bought a Tran-x now. I would have thought a plate diff was better for a rally car as the ATB acts as an open diff when there is zero torque on one wheel. Has anyone tried both types on a rally car?

elie boone Posted February 1, 2002 Share Posted February 1, 2002 Chris, I expect the Tony Thompson ali diff next week the LSD is a progressive one, do you by any change know of this is a tran-x unit or ZF. BTW have you been lately in your garage to weight some things ? Link to comment Share on other sites More sharing options...
Noel Mclaughlin Posted February 2, 2002 Author Share Posted February 2, 2002 Thanks everyone for your input, will pass info on to my friend for his attention Link to comment Share on other sites More sharing options...
R2D2 Posted February 2, 2002 Share Posted February 2, 2002 Elie, I don't believe that ZF make a diff for the English axle. Tran-X make their own design and have bought the manufacturing rights to the Salisbury unit. I think the progressive unit is their own design, which I have used and found quite reliable. I have managed to find one of the back brake plates and will dig out the other this weekend. (Been trying to finish the Escort for next month!)
