Thread: Clutch Slip?

I doubt any slip is normal… You can try in lower gears too, left foot on brake and then give it a little throttle to see if it will slip…

Any oil leak from the bellhousing? That might have contaminated the clutch? Also, is the clutch pedal coming up fast/immediately if you slip your foot off sideways (engine off)? Slow May indicate a blockage or faulty slave cylinder?

Clutch pedal comes up real fast - seems fine. About an inch of free movement on pedal before pressure too. I thought the pedal/master cylinder rod may have been out of adjustment - but that seems fine.
There is oil down near bellhousing. 2 engines later and despite religiously degreasing and pressure washing there has always been oil down there. I am hoping its not rear main. Always seems to ooze from 300TDi engines at rear of sump/t-seals. My engine does not use oil between changes etc.

How long should a clutch last on a Disco that gets used as a 4wd but not abused?

One of my Brothers has a petrol,original clutch,done just under 400 000KM.

It has a towing trip coming up shortly,so i hope it is still going strong....

There should be no slip under any circumstances with this vehicle.

In my experience most clutch slipping is due to oil contamination of the clutch, which can have leaked from either the engine (usually rear seal) or the gearbox, rarely from hydraulic oil from the slave cylinder leaking.

The other cause will be worn driven plate. The life of a clutch plate is almost entirely dependent on the driver, and can vary from tens of thousands of kilometres to hundreds of thousands on exactly the same vehicle. The worst wear comes from drivers who use the clutch pedal as a footrest, but there can also be excess wear from excessive slipping when starting off and failure to match engine revs to the gear when changing gears (which also wears synchro).

I hate that gearbox-out feeling…

Exactly my feeling. I have been annoyed about it all day! haha
And clutch kits aren't cheap either...

Agree with everything above, shouldn't slip, could be a lubricant of some kind on the clutch.

Could be a collapsed/weak spring/springs in the pressure plate, assuming that was replaced when the clutch was done?

There is an aftermarket rear main seal for the 300tdi that is FAR superior to genuine, if you are interested I'll go find it for you.

I have always bought the 300tdi rear main that Turner Engineering sells.
Is that the one your talking about? If so, where else can it be bought from?
