Complete loss of drive

Vehicle 1996 Disco V8 R380 Manual. Ashcroft one piece transfer box diff pin, ashcroft lsd diff in front and kaiser locker in the rear.

As per title, was out offroading today when going up a 2nd gear hill i had to stop and reverser down. as i came down in reverse i notice there wasn't any engine braking and when i went to pull away i had no drive at all!

There were no bangs, clunks or any noises leading up to this happening. Towed it up to flat ground and checked...

Jacked up the rear of the car with it in diff lock and spun a wheel..the transfr box was locking up so it doesn't seem to be that

Took the transfer box rear cover off to see if the gearbox output shaft had stripped its teeth..it hadn't.

You can turn over the engine by hand via the crank with it in difflock and in gear with all wheels on thee ground.

Still has a normal clutch pedal feel

When the clutch is released and its in gear with the transfer box in put gear removed the output shaft of the gear box will spin but not smoothly,as it it seems like there's not alot of force spinning it.

Seems to me like the clutch might have gone or maybe the mainshaft in the gear box has sheared!

Any thoughts?

drain some oil out of g/box and check it ,it should either be clutch center ,input shaft teeth or sheared rear end of mainshaft ,does it work in 4th

Gear oil looks good, checked the rear end of the main shaft in the field with the T/B input gear removed still all nice square edged teeth. doesn't work in 4th that was my first thing to try. Also i forgot to mention that with the engine running i can select any gear with out resistance without depressing the clutch pedal. So fingers crossed it's just a failed clutch!

look carefull clutch center can often break but not look so

Not had the box off so i haven't been able to check the clutch yet

the diff lock levers not in neutral is it?



forgive me if you've checked but it's been done before

Checked diff lock as first though was a blown T/B diff pins. Jacked up a rear wheel and spun it with diff lock on and it locks up the props fine.

ok worth asking though just in case.

listen carefully to JamesMartin

Turned out to be a snapped main shaft. Oh bugger!

Not part of the 'problem', but where did you get the kaiser from, and what do you think about it?
