I'm needing to replace the gearbox in my Fiesta Zetec-S as the diff has had it, however I'm looking to uprate the box while I change it all over, however I am struggling to find out if its the LSD from an S1 or an S2 I need.

Can anyone advise me? And also does anyone have one for sale?

Thanks, Rob

 

Hi rob, its been along time since i have messed around with a gearbox but if i remember right the lsd's out of S1 & S2 are pretty much the same! think S1 has 6 bolt holes and S2 has 8. dont hold me to that tho!

Would you have any idea whether either would fit the IB5?

I'm really struggling to find one, seen a few still in boxes, but would prefer one thats been removed!

 

i should of thought so as the BC gearbox and the IB5 gearbox are more less the same box just with starter at the rear and few other little things.... bigger meanshaft bearing and 4 bolt holes on the front, etc
they both use a 20mmx17spline input shaft!
Not that its any help to you now but i just scraped a broken (meanshaft bearing) gearbox with LSD. sorry

 

That's useful to know, thanks for that!

And as for scrapping the box

 

S2 diff is what you need, thats what i have in my Ib5

 

Cheers!

Does anyone know of anyone selling one? I've tried eBay without much luck.

 

silly question but dont series ones come without a lsd?
thought only series 2's had them fitted

 

No S1 comes with slip diff too! i think they are a bit more harsh and cut in bit earlyer

 

Early boxes had a 6 bolt attachment to the crown wheel , later boxes have 8 bolt , you need a later type to be able to bolt it to your crown wheel , it is quite easy to do , doing one for my frst as part of its rebuild .

 

is this just bolt on? I mean , is lsd just needed to be put in box? or need to change some bearings, special tools ...? I have fiesta st and LSD from 88 rst S2 and want put this together
