Thread: Disco 1 handbrake pads oily again !

its the rear output seal on the tcase, in a workshop it takes about an hour to change and is 2/5 spanners in difficulty.

theres several threads on doing the tcase seal in the lt230 tcase.

but I can do another run down if you cant find them.

It will be the rear output seal on the transfer case. While getting the seal done make sure the felt washer that seals the splines is replaced too.

Probably worth checking the transfer case breather isn't blocked as that would pressurise the transfer case causing leaks.

Thanks a lot, I'll have a look for them. Mine is a 200 Tdi 93 Disco so that info still stands ?

Appreciated.

yep....

its the same procedure from the series one all the way to the puma, just some sizes and sequence changes.

i replaced my felt washer with silastic.........


i just put a bit of sealant on the end of the splines on the flange.......the outside edge........
not the edge that slides into the transfer case.......

I replaced both seal and felt washer and after doing so encountered these same leaks. Could the breather being blocked really cause a leak this bad?
Perhaps I'll be looking at mine.
I pulled the seal and re-seated it with no success.

Id agree as others have said, felt washer and rear oil seal.

ALSO.... Check for a warn output shaft.

Basic principle of changing / checking is simple.

1. Rear prop off
2. remove big nut from output shaft
3. slide out output flange
4. check for wear on the shaft. If there is even the smallest 'v' shape worn into the shaft, replace it otherwise it will always leak, no matter how many seals you throw at it!
5. Remove oil seal, replace with new (GENUINE part) - take care not to score the transfer box when using a big screwdriver to prize the seal out!!
6. Re-assemble in reverse order.

If there is a small score in the shaft it is possible to not push the new seal all the way home, that will hold the oil back a little, but is only prolonging the inevitable.

My mechanic read your post and did exactly the same. Said the seal he put in was fine as was the breather. Thanks, hopefully that's the end of that.
