There is a small amount of oil coming from the handbrake casing on my 300tdI Disco P regd.1996.
1.I would like to know whether it is possible to change the oil seal on the transmission box from within the handbrake casing.
2.Would I have to take the prop shaft off completely or is it possible to clear the nuts by compressing the prop.
3. Are there any problems or pitfalls I am likely to encounter with tackling the job myself.

p.s This is not the only oil leak

Thanks Tony
 
Have found a couple of similar threads but would like some ratification as to whether this is the same for this model Thanks:confused:
 
Your transfer box oil seal has gone.There is a good post on this with pictures titled" How to replace front transfer box oil seal".I only know this because Ive just done a transfer box oil change and after taking her for a spin noticed oil ****ing out of same place. :(
 
got the P reg in pieces at mo,oil leak into handbrake as per usual,ordered new seal for transfer box output shaft,rubber/plastic sprung one appeared,took apart...lo and behold FELT seals/washers on shaft.....?????

Anyone got experience of this?It harks back to my days working on military bedfords.....

do I need them?Where to get em?

Answers if you got please ladies and gents:)
 
The felt seals just stop a small amount of oil finding its way along the splines and coming out behind the nut. I always smear a little slicon on them before replacing and never have a problem.

Be sure to check the gearbox/transfer box breathers are clear whilst under there.

If you look under the bonnet on the offside coming out from the bulkhead area and about level with the lift pump there are two small bore black pipes open to the air.

These should be clear, they lead back to banjo connectors on the top of the gearbox and transfer box. They need disconnecting and blowing through to see if they are clear.

I know someone who just undoes the filler plugs and pushes a tight rubber hose onto the pipes and gives them a puff, this is OK to confirm they are clear but if they are not then the crud goes into the boxes.

Best way is feel your way around the boxes and clean off around the unions and undo them, and then blow them out.

There are breathers on both axles and one to the fuel tank.

If you are planning plenty of off road action in or around mud/water then consider re-piping the breathers higher up in the engine bay or run them up the inside of the snorkel exiting at the top.

I got a complete kit from a guy on ebay search for breathers - wizard, the kit comes with all new connectors a manifold to link the pipes and does everything with pipe to spare

Yep! It's not uncommon for a breather pipe to become blocked through mud ect, if this has happened then as you drive the car and the transmission oil gets hot so does the air inside.

The air pressure rises and tries to escape through the easiest route, this is normaly through the breather but if it is blocked then an oil seal that is a little on the old/worn side becomes the escape point and so out comes the air and it brings the oil with it.

A reverse situation can also occur, you drive your hot vehicle in to cold water with blocked breathers the air inside the casings cools creating a vacuum and again if the breathers are blocked water can be drawn in through the various seals.
