Travelling back from Ashby Folville yesterday,pulling away nicely.
Went from second gear to try third and all hell breaks loose in the clutch/gearbox area crunching etc.
All pressure was lost at the peddle,but mananged to get her pulled over.
Im hoping its just a /Hydralic/clutch/bearing failure.
The gear is engaged but no forward movement.frown

I really want to be at SCH, so does anyone know of a garage in my area who could turn this around quickly for me.

Many thanks to Dave M and the other great people who pulled over to offer assistance.

Thanks Andy

I take it that the clutch will not disengage (ie you can't get into gear with the engine running).

If so,

1. is there any fluid in the clutch reservior? it should be nearly full.
2. if not, is there evidence of it leaking from the master cylinder (look for fluid on the bulkhead, around connections and where the rod goes into the cylinder in the footwell).
3. is there evidence of it leaking from the slave cylinder (harder to see this one, you'll need to jack the car up).
4. is the clutch actuation lever still connected to the slave cylinder.

Most likey your slave or master cylinder seals have gone. This isn't a particularly difficult thing to fix, but getting the slave cylinder off and on again requires a degree of uncomfortable grovelling under the car.

The hydraulic components are very similar to Land Rovers (old style) so if there's a specialist round you somewhere that might be an option.

Dave M I think has a friendly local garage in Leicestershire - - or as an alternative I'll come over and do it at your house - Im only up the A46 and kicking my heels at the moment 'between jobs' irked

I'd suggest replacing both master and slave cylinders and be done with it.

Will get in touch with Adrian if I need a new Clutch thanks Norman.

The clutch is not engaged and you can select the gears with the engine running.
The clutch resevoir is fully topped up and dosent appear to be leaking
The slave cylinder was replaced by the previous owner.
I Will get her pushed into my garage tonight to check the operation of the hydralics,etc.
If it is just the Hydralics I can fix that,but if its the clutch a garage gets the job.
Thanks for the offer Chris if I do run into trouble you might well get a phone call.

I will let you know how I get on.
Cheers Andy

Oh dear.

As you can imagine, I'm particularly upset to read about this.

If you've got no drive, then either the clutch actuation has seized ON, or something in the drivetrain is broken. If the former, the feel of the clutch pedal will be abnormal. If it's not, then the latter is likely. This could be anything from the clutch itself backwards (gearbox, propshaft, diff, halfshaft, etc) and is not likely to be trivial...

Sorry...

Hello Graham,


You will be pleased to know she flew through the MOT no problems.Got her pushed into the garage and it looks like the clutch is the culprit.These things happen.My neighbour who has a Spitfire(closet TVR owner ,I am working on him) uses a local engineer he highly recommends meeting him tonight, will also give Adrian a ring, so looking good for S club.

Andy...oh well, it could have been a lot worse mate...are you getting it done at the garage or having a crack yourself?

Cheers

I have decided to have a crack myself.Quite enjoying it to be honest smile.Should have her stripped by mid week.Found a lot of clutch plate debris when I took the starter motor and slave cylinder off.
Keep you posted

Well the gear box is out, a good old fashioned challenge that was. This forum has proved invaluble and I dont think I would have attempted the job without it.The S3 rebuild link from Mep12345 I think, is spot on and saved a lot of time head scratching. As suspected the clutch has given up,everthing else the diff,propshaft gearbox etc seem fine.
Couple if pics

bounce Well done !!! bounce

Looks like further proof that the gearbox CAN come out without the engine.

The race is on to get it back together in time for SCH09 woohoo

Good luck,
Graham

Wow thats a pretty spectacular failure!

Just make sure there isn't a cause before you put it back together - does the bearing feel OK on the input shaft to the gearbox and check the spigot bearing in the end of the crank where the end of the gearbox shaft engages - if thats gone then the clutch would have been spinning offcentre.

Probably just a strightforward failure though but worth checking, I'm sure you wouldn't want to be removing that gearbox again in a hurry!

Change the spigot bearing while you are there it costs about £10 and with the right tooling (or use of my home made one) comes out in minutes and if it fails after the box goes back in will require a repeat of the whole job

Thanks gents for the kind response.smile

I will change the spigot bearing be daft not to really.Might have a tool at work that will do the job,if not I will have ago at making the Mk11.

Having had a proper look at the gearbox, the output shaft has got a slight wobble on it.I guess this is not correct.The splines are in good order, should there be any movement from the shaft ? As much fun as its been, I dont really want to take the gearbox out again.

eek Jim could not fix that!

There will be a bit of play in the input shaft - thats normal.

I doubt its the gearbox, possibly the spigot bearing but I think equally as likely the clutch has just fallen apart with age / corrosion.

My box came out for a rebuild and even once done there was a small amount of play in the input shaft (quite a bit before as the box was shagged). I assume the spigot bearing is designed to hold it still.

You will need two people to get the box back in really because you MUSTN'T put too much strain on the input shaft and it is a real bugger to line up. The way I did it was to have one person each side of the car with one holding the weight of the box and the other manoeuvring it into position and sliding the input shaft through the clutch and into the spigot bearing (getting it in the spigot bearing being the hard part due to chassis proximity to box webs and freedom of movement)

Good luck

Mark

hey up Andy


Good to see you are getting there....but I do think your clutch lining might be worn down below the recommended limit....

Can you do me a favour while you are under there, and get me a photo of the gearbox mountings, and how the chassis cross piece comes out please...I'm just sussing out if I'll be able to get my gearbox out without removing the engine.

Good luck with it mate, and think of the satisfaction/£s

Cheers

Ant

Thats confirmed what I thought about the input shaft.Cheers

I think your spot on about the clutch.looks to be the original.So a new spigot bearing is on the shopping list.

Another Question I have I Initially rang Adrian@ about carrying out the work for me.Really nice helpful chap,off to Norway to deliver a TVR he was.I understand he has had to correct clutches,that start to slip after a few thousand miles service.Again not wanting to pull the gearbox out again do you think its prudant to do this mod now,or if I fit a like for like clutch, that should be ok.

Cheers Andy
