Hey all...Abit of advice for my F-Plate S2....

1st:
When the clutch is up the gearbox "wines", when the clutch is pressed down its silent...Am i right in saying its the release bearing??

2nd:
when looking for parts it states "early" or "late" gearbox..Am i right in saying S1's are the early non LSD boxes and the S2's are the late LSD boxes...So parts like the "BC Gearbox Clutch Bush" & "BC Gearbox Pinion Shaft Oil Funnel" should be for the late model right? Are these worth replacing while im doing it?

3rd:
Im up for overhauling my gearbox, is the following a good kit off ebay or any Recommendations:

Thanks in advance!!

1: it sounds more like a gearbox bearing on main shaft than the clutch release bearing.

2: not sure what they mean by early or late box. The s1 is essentially the same box in a different casing, both the s1 and s2 have LSD, different ratio and I think the s1 is a 6 bolt diff whereas s2 is 8. Don't quote me on that bit though.

3: without seeing the parts can't comment too deeply but for a standard box and power it doesn't seem too unbelievable. It's not so cheap that you'd expect shit parts, recon boxes are usually priced at couple hundred cause of the labour involved stripping and rebuilding.

If you're going to the trouble of rebuilding it I'd get the ib5 bearings put in cause they're stronger. Requires a little machining to the casing but should make it last a little longer if you've upped the power.

1: Gearbox bearings (Clutch depressed, gearbox disengaged, silent... Clutch up, gearbox engaged, noisy).

2: It's referring to the BC (early) IB5 (late) bearing size differences. Aston is correct, both have LSD and the S1 is indeed a 6 bolt and the S2 an 8 bolt.

3: Don't bother rebuilding your box and certainly don't waste money having your casing machined out to take the later (IB5) bearings, the weak point of these box's is case flex and ultimately the shafts and gears themselves, the most cost effective method of having a fresh and slightly stronger box is to use a MK6 Escort van gearbox casing (IB5 but front starter and cable clutch), a 1.3 Ka gear set (IB5) and a S2 LSD (8 Bolt), the IB5 casing's have more webbing to prevent flex and bigger bearings as standard.

Thanks for your info guys...food for thought...My cars 250bhp so am thinking towards the MK6 gearbox...Any of you guys know where i can get one ready made...Or anyone got one for sale...Worse case 3 items to be bought:
1) mk6 escort van gearbox
2) 1.3 ford ka gear set ib5
3) LSD diff - but this can be used from mine right?

With your power in mind i'd certainly go for a later box instead of rebuilding.

My next box upgrade will be an IB5 with my S2 diff tightened up, and an M Sport group N Fiesta ST gear kit i've got in a box.

I dont plan on more than 200bhp/lbft at the moment anyway so im not too worried.

iTrader: (4)

I can put one together for you but it sounds as though your happy to have a go yourself anyway, yes you can use your S2 LSD.

RSB

How much could you do one for complete, could you fit if i was to come to you?...
Unless you have an lsd spare im assuming you'll need mine out of my box?

Karlos G

iTrader: (4)

I can build one up but I'm not fitting it, that's a really shit job and I'd have to charge too much money to make it worth the ball ache! lol
Let me work a few things out....

RSB

Dont wanna get ya hands dirty ha?...lol i dont blame ya...Worse case i'l re fit myself....Let me know what you come up with dude!

Karlos G

It's not that I've just done it so many times and it's my most hated job, some times it goes on really easily but most times it's a bitch! lol

Im deffo in favour of having a go, thats why i bought the group N gear kit.

Very worst case scenario you drop it at a gearbox specialist in kit form tell em you bought it like that and would like it throwing together. But if you take enough videos/pictures of how it came apart and take notes then its hard to get wrong.

Karlos dya know whats involved in tightening the diff? GEARS offer this:
(http://www.gears.tv/features/stage1.pdf)

Is the standard diff adjusted or have i misread it and it actually means you swap for an uprated one and pay the extra?

Karlos G

iTrader: (4)

You have misread it yes! lol
That's the torque rating they have given their uprated LSD, there is no diff tightening, you fit the crown wheel and bearings and it drops in.
And IMO it's also way to low, I've never actually seen a diff break in an RST, it's always the gears stripping teeth or shafts snapping.

I figured as much, it doesnt mention anything about extra cost though.

The LSD is a viscous unit correct? Meaning a thicker oil makes the diff lock more positively?

Im using Titan Race SYN 5 75W-90 at the moment. Seems quieter than whatever was in it before.

Karlos G

iTrader: (4)

Probably need to call them for pricing.
It is viscous yes but the gel is self contained so what box oil you run doesn't effect the lock up percentage.

AstoN_B

iTrader: (1)

Ahr, does the gel wear out or degrade over time?

I always thought the viscous part used the drag from the gearbox oil to spin the other wheel. (Obviously lamens terms lol)

Thats why they over heat on drift cars and basically fail?

The next box stage they offer is their stage two which is basically the same as one above but with the quaife diff. which is Ł500 more than their stage 1.

Only experience ive had of an ATB quaife was in a focus st with some bolt on bits and a map. It was horrible!

Karlos G

iTrader: (4)

Yes it does, they can be re gelled.
Are you looking to buy a box from them then mate? I can build you up a nice IB5 for not much money if you don't fancy it yourself.

I was just looking at their specs really cause I've got a fiesta ST group N gear kit and an LSD boxed up. I'm putting it off til I NEED to cause my box is fine ATM. How long for once boost is up I'm not sure but it's ok for now lol.

I got quoted Ł150 to simply put my LSD into the box when I was rebuilding engine on my 3i. Figured I'd enquire while the box was sat on floor drained of oil. I quickly thanked them, hung up and cracked on putting it together and filling with the fresh oil lol.

Gearbox and steering rack are pretty much the only things I haven't stripped and rebuilt over the years now so ill tackle them as and when they need attention.

Are the mk6 van ib5's hard to get hold of? Seem to come across everything but those when having a nosey about.

Karlos G

iTrader: (4)

Having just looked on ebay there's fuck all, but seeing as there are literally thousands of Escort Van's kicking about I'm sure your local scrappy will have one.
Not worth anything which is probably why there are none on ebay.

Yeah ill have a ride up to Fleetwood ford breakers when the time comes. He's got acres of bits stacked up.

Any in particular to recon the diff or can most transmission places do it?

Karlos G

iTrader: (4)

TBH I have no idea, never had one done! lol

stratomt

which lsd fits to my xr3i 1987 gearbox s1 or s2 once?

Release bearing would rattle if faulty not whine, sounds like something is wrong internally

I got a fully rebuilt spare I'm selling
