BillyWhizzz2002 Posted August 12, 2006 Author Share Posted August 12, 2006 I have been crawling about under car this morning and found some lettering & numbers ect on the part of the dif that is not the westfield casing. On one side i found a ford emblem followed by these letters/numbers....8C20, then on the other side of dif i found a long number like a serial number, also there is the following....T20 All the letters etc are raised out of the metal not stamped in. Also checked oil level & it is about 2mm bellow level plug, and seems to be clear oil with a greyish tint. Its not like that red ATF stuff in my gearbox. Just one other point, where the hell do you put a spirt level on car to make sure it is level when trying to jack car level on a slight slope. (no level ground near me anywhere) Quote Link to comment Share on other sites More sharing options...
pist-n-broke Posted August 12, 2006 Share Posted August 12, 2006 got a quiafe on mine, when i first got the car it would make some unusual noises from diff when hot and turning sharp after a bit of research found some oil by redline called lsd friction modifier , did the trick !

If you have a type 9, then ATF in there is *bad* and must be removed immediately and replaced with a proper gearbox oil to GL4 spec. Viscosity is pretty much irrelevant, as long as it's a GL4 spec oil.

BillyWhizzz2002 Posted August 13, 2006 Author Share Posted August 13, 2006 Cheers for where to spirit level blaters. My car has a type 5 gearbox out of cossie. So the ford emblem on the lsd casing means nothing..(damn) i thought it may have narrowed it down. I have seen the alloy lsd on sierra's n grandads and it looks nowt like them. I wouldnt have thought that ford would have made that many diferent types. You mentioned earlier that the westfield casings were made for mk 1 & 2 escorts. Mine looks nothing like the new ones so do you think it could be one of them? Quote Link to comment Share on other sites More sharing options...
stu999 Posted August 13, 2006 Share Posted August 13, 2006 The rear (alloy) section is bespoke Westfield, whilst the nose is from the Escort. You are correct in that they didn't make that many types. However, the nose sadly does not relate to the LSD inside, which will almost definately be from a different source than Ford... Quote Link to comment Share on other sites More sharing options...

A piccy of the diff would be handy... Quote Link to comment Share on other sites More sharing options...
BillyWhizzz2002 Posted August 14, 2006 Author Share Posted August 14, 2006 Hi blatters, My car is a seiw with pinto engine, type 5 gearbox. Lsd with westfield casing. the build was finnished in 1994 but duno when it was started? I cant post a picy as i dont have that avitar stuff, i have tried a few times but no good. Can i e-mail you some pics? i really would like to get to find out what i have in car. cheers... you can e-mail me at; billywhizzz2002@hotmail.com Quote Link to comment Share on other sites More sharing options...
Blatman Posted August 14, 2006 Share Posted August 14, 2006 Send pics to blatmanuk at yahoo dot co dot uk. If you have a Westfield cased diff in an SEiW then it's an early wide. Type 5 I suspect is longhand for T5, which is the gearbox from a Sierra Cosworth. You'll never break it, but I still think that the tunnel will have needed modifying to accommodate it, as I'm fairly sure the early Escort diffed wides were built for Type 9's...

BillyWhizzz2002 Posted August 14, 2006 Author Share Posted August 14, 2006 Cheers blats, Piccys have been e-mailed. feel free to post on here if you like to give others an idea of what i am on about. Quote Link to comment Share on other sites More sharing options...
Blatman Posted August 14, 2006 Share Posted August 14, 2006 Well swipe me sideways... It is an Escort diff as we suspected. And it does look like a T5 gearbox. I'm dying to know if this has somehow been shoehorned in there without chassis mods. So, we now need to work out what sort of LSD it is. There are but two choices. 1) an ATB, which requires no special oil, or 2) a plate type which does. I'm afraid that the only reliable way I know of telling for sure is to pull the diff out and crack it open. Unless someone else has any better ideas...

blankczechbook Posted August 15, 2006 Share Posted August 15, 2006 http://www.mycaterham.com/66828/117416.html this page shows some help if checking what type of diff - if it is relevant in this case.... HTH Quote Link to comment Share on other sites More sharing options...
BillyWhizzz2002 Posted August 15, 2006 Author Share Posted August 15, 2006 Didnt think we could every surprise you blats....lol Yes it is a T5 gearbox too. Duno it it has any chassis mods tho? Duno what to look for. Is there anything i could see by looking through level plug in westfield casing? Dont fancy taking it apart, never done owt like that before not sure on how to do it.

Blatman Posted August 15, 2006 Share Posted August 15, 2006 *Maybe* *perhaps* *possibly*... Shine a light in to the drain hole. Look towards the centre of the diff. If it looks like a washing machine drum, but without the holes, it's probably an ATB... Quote Link to comment Share on other sites More sharing options...
BillyWhizzz2002 Posted August 16, 2006 Author Share Posted August 16, 2006 Will have a look later to see if i can see owt. You say that a plate LSD needs special oil, what is it? & wont the special oil do for a ATB. by the way what dose ATB mean or is that a make and not a type? cheers.

Blatman Posted August 16, 2006 Share Posted August 16, 2006 ATB = Automatic Torque Biasing. It needs no special oil because the slipping action is taken care of by moving gears. In a clutch type LSD, special clutch plates are used to limit slip, and these need a special oil that lubricates whilst not affecting the grip of the clutch plates so that they can do their job. The Castrol web site has some brief information on gear oils which may help a bit. Plate type diffs would use the oil that is listed as being for rally cars, IE the B373...
