Agribuggy 4D gearbox

[Neddy flanders]

Hi anyone outhere know anything about these?

as I understand it is a Escort diesel engine and then I seem to remember it is ???RS Cosworth gearbox????
although I may have got that all wrong.
behind the bell housing is the gearbox with a rear and forward drive shafts coming out of it.
next to the forward shaft, is the plunger going into the gearbox which has a ribbed rubber protector on it. this plunger has two cables and a mechanism linking back the gear lever.
where the plunger goes into the gearbox, oil is seeping out very slowly. its a clear fine oil not engine oil. guess its gear oil.
im a bit crap on engines so if anyones got a minute it would be appreciated. ill try and post a picture.

It’s just an escort gearbox, if you want the limited slip diff you’ll want a gearbox off a RS turbo, I changed mine years ago, just put a standard reconditioned one on, did a few years with it no problem then got a bigger sprayer and sold it.

Have I got to change the gearbox to sort the oil leak from the selector or is there a seal ?

Is it much of a leak or just a drip keep an eye on the oil level. There is probably just a shaft seal in there so you can just repair what you have got

Sorry I don’t know, I’ve just re read and see I’ve misunderstood you, thought you asking what gearbox you needed.

It should be an RS turbo box with the lsd diff. You can use most b5 boxes, but the ratios will be different as will the final drive. The clutch is escort 1,8 d or td, but a rst paddle type is stronger. O ring on the selector shaft and oil is 75w90 .
