Clutch has gone?

grinder · February 14, 2009, 02:54:12 PM

isnt there an inspection panel that you can remove and look at the clutch - or is that just on FD\'s

so when you push down on the clutch - you can see the slave cylinder moving freely ??

the only thing im thinking - is it moving enough .. is there any slack in it ( not sure if this can actually happen or not though ! )

and i take it that the car is now stuck in gear

So with engine running it can\'t be put in gear, but if the engine isn\'t running you can select gear, and then when you try and start the engine it lurches (suggesting still in gear).

Could be clutch is worn, pilot bearing or release bearing - either way - all that should get replaced with a clutch kit

dthebuk · February 14, 2009, 04:45:13 PM

car is not stuck in gear, prof is right.

as for how for how far the slave cylinder moves, i honestly don\'t know how far it should move. At a guess it looks like its moving about an inch, maybe 2.

Looking through the diagrams in the haynes manual, there doesn\'t seem to be an inspection pannel.

Is a bent clutch fork something that can be checked outside the transmission? I\'m not to sure on how far it goes in.

If the fork is fine, how sure can any of you guys be that its one of these bearings that has gone? Ive read/been told by others, that if the release bearing is damaged the car should make a noise in neutral with the engine running. So that puts pretty much all of it down to the pilot bearing.

Right so any idea how much rotechniks would charge me to sort something like this? I would ideally like to fix it myself but dropping out the transmission with a car on jack stands isn;t my idea of a good time....seeing as the most hands on things ive done have been playing with lights and air intakes. Anyone wanna lend us a garage with a pit? :cheers

Quote from: dthebuk;584447its on 89k now. The last owner had it garaged for ages. Did you get it rebuilt at RX motors? it had the most shocking receipt ever. Er it had a bit of history.
All fits in a clear plastic wallet though and it doesn\'t date back that far.

did you have the clifford put on the car? its got to be the most anoying alarm ive ever whitnessed :spank

LOL the alarm was a PITA ! had it towed once 50 miles once a week after it was first fitted.PM for more details best not said on here.

RX-motors did the rebuild with new housings as in pic above.
Clutch and decat down pipe from RX motors

RearExhaust sections from WGT
and boost chip as they call it.
+ pulley and belts

gauge\'s and both strut braces, and uprated diff mounts all from USA
Brake disks from Rotechnic

thats about all I remember was a while back and of course the car has had a
few owners since so things change.

Hope this helps

pm sent.

well thanks for all the info

i\'ll have to look into these diff mounts and the disks, had no idea about them!

Paul-Tll · February 14, 2009, 05:16:02 PM

Just thought ..
Did you know it is prob. the youngest Coupe in the UK.
(before you go drifting-no pressure lol)
Theres a few Cabs newer or reg. later though.

no idea what people charge - but it cost me Â£117.50 to get a clutch fitted at WGT ( i supplied the clutch )

im SURE there is a recent post in the 2nd gen forum about someone asking about a clutch ??

Sounds about right - the cylinder moves the clutch fork - and it\'s pivots on the bell housing - so it moves the fork a bit more than that. If it\'s got out of shape then it may not move the clutch in or out far enough.

Quote from: dthebuk;584499Looking through the diagrams in the haynes manual, there doesn\'t seem to be an inspection pannel.

Not sure about all bell housings, but I have a plate both on the bottom and top of the housing that appear to serve no other purpose - there are a couple of 10mm bolts that hold a thin plate on - so I am guessing they would allow you to inspect the clutch without taking the thing off the car. If you\'ve got the stock intercooler - that will most likely have to come off, not sure whether you can get to the top plate with that off - I\'ll go have a look tomorrow in the daylight - post a pic.

Difficult - not sure if you\'d see it through the top inspection hole.

Ive read/been told by others, that if the release bearing is damaged the car should make a noise in neutral with the engine running. So that puts pretty much all of it down to the pilot bearing.

I had a problem with my pilot bearing - the car would select gears fine when it was cold, but at some point the clutch would become useless - leaving the car in gear - and prevent seleting gears. I suspect that this fails in more than one manor - so your symptoms may point to this. Apparently the bearing was slipping on the shaft as it warmed up - so if the car was left to cool - it would be fine again.

Can\'t remember how much they charged me now - they had to rework the end of the shaft so the bearing would sit firmly on it, and the labour would be equivalent to a clutch change (about 3-4 hours) plus a bit - parts shouldn\'t be much if the clutch is in good shape - but if it\'s got wear and tear it would be a good time to change it anyway, as the labour cost wouldn\'t be any more. It\'s defo not a job you want to do on the driveway - been there - not comfortable at all. Plus if you do go ahead and attempt a job like that - wedge the engine at the front - as when you undo the bell housing off the back of the engine - it will rock forward on the engine mounts and you\'ll never get the gearbox/bell housing back on it again without a massive struggle

cheers stu.

never knew mrp fitted clutches though?!

it looks pretty cheap so mybe ill pay someone to do it, i was getting rather excited about it actually!

dthebuk · February 14, 2009, 06:05:52 PM

cheers for all the advice.

you guys are legends

I think i\'ll see what can do tomorrow then give mrp/rotechniks a ring and get some quotes.

a garage with a pit sounds like a decent future investment tho....bet they\'ll cost a bomb though!

TiddlesRX7 · February 14, 2009, 07:35:45 PM

Just find a hole that the council have dug in our roads. Pull the car over the top of it and hey presto, got yourself a pit. You do pay your road tax after all!

dthebuk · February 14, 2009, 07:37:37 PM

haha that might be signature worthy!
