Thread: discovery 1 V8 clutch problem

You can unbolt the slave cylinder and see if it's stuck, or if the push rod is in or out. Anything else is a take engine (or gearbox) out routine.

Hi there again,

Right i have now removed the front and rear prop shafts and all other bots, cables etc and the gearbox is just sitting there awaiting removal (although, i cannot remove due to needing to purchase a trolley jack.

But i want to order a new clutch kit and cutch fork.

Please could someone tell me of good land rover parts supplier and at a reasonable price so that i can obtain the required items.

Cheers Nick

It would really help if you put your location in your profile, Nick.

I use these guys in Melbourne and find them excellent to deal with.

G'day Nick,

I changed the clutch on my '91 V8 Disco prior to a big trip in remote areas.. It was more of a precaution than anything because the previous 190,000 kays were unknown to me and it had copped a bit of abuse at Stockton Beach. Anyway, it came off at 235,000k's and had heaps left on it, so depending on your miles it may be okay. Slipping clutches are associated with bad smells and noises and a rapid loss of clutch pedal pressure you describe seems to point toward a fork or hydraulic issue.

The forks on these things (V8's) are meaty cast iron units, so unless you felt it snap it's probably the slave or master either sticking or loose in the bore and therefore not pressurising the fluid.

I've also replaced both these units (at 260,000k's) and it's a pretty straight forward job - just remember to have the bleed nipple 'up' on the slave otherwise it'll never bleed the air out - that was my experience anyway.

If you do want to drop the gearbox it can be pretty dodgy balancing it on a trolley jack - i removed the transfer, resting it on my guts, then slid out from under on a workshop trolley, then the same with the gearbox. Doing it this ways makes it more manageable and they're not that heavy to re-fit in the same manner.

Anyway mate, good luck with it. I suggest its a slave/master cylinder issue. I'd varify these units first because removing and refitting the gearbox/transfer on your own is a fair mission (read; bastard of a job) .

Matt.

Just a question, when did they change to the crappy pressed steel ones used on the Defender TD5?

Hi Diana,

I'm not sure. I intitially thought it would be some pressed piece of junk but was correctly informed by a fellow at Graeme Coopers that it was cast, and on removal of the box - hey presto!

It's a shame because I understand they (pressed units) wear through on the pivot...

Thanks Matt.

I dunno those people at Graeme Cooper Automotive, they seem to know what they're talking about !

(Am having a problem with my throttle position sensor sorted there on Thursday.)

Still no wiser about the tinny clutch fork though, perhaps Graeme or Ward will know.
