Title: Clutch setup
Post by: Rangie3.0LtrDan on January 10, 2006, 21:45:06

Hi there,

On my 200tdi discovery i am told that the clutch possibly needs bleeding at the slave cylinder.  I have 3 questions:

Where is the slave cylinder.

Where is the reservoir for me to put the fluid in.

Do i use brake fluid or is there a special clutch fluid?

Cheers

Dan

Brake fluid
Reservoir is next to brake master cylinder
Slave cylinder is on the bellhousing and accessible from under the car

Also someone who has bled systems before, its the same as doing a brake system, only easier, not so many bleed nipples to deal with.

For a first time its a lot easier with a 2nd person, although the easy one ma bleed kits are quite handy too :wink:

Just tried to bleed the clutch.  The master cylinder is full.  When i put me foot down on the clutch very very little fluid is coming through.  Does this mean one of the cylinders isnt working?

Cheers

Dan

Dan it may be that it needs bleeding at the mastrer cylinder first, I would try that and then start looking for other things.

Ok, so i presume there is a bleed screw on the master cylinder? somewhere easy to see lol

depends on if you open your eyes  :lol:  :lol:  it is fairly easy find the pipe that comes out of it and have a close look I am sure you will see it

LOL ok, so let me get this straight so i dont [!Expletive Deleted!] it all up, i take the pipe off the master cylinder, put me own pipe on, pump the pedal and see if anything comes out, if it doesnt then i might just need a new master cylinder?

Title: Clutch setup

NOOOOOOOO!!!!!! under the pipe on the master cylinder is a bleed nipple put your bleed pipe on that and then loosen then bleedas you did the slave cylinder. and you have my number if you get stuck but I aint popping up to help  :o  :o  :lol:  :lol:

Post by: Rangie3.0LtrDan on January 17, 2006, 15:10:38

Houston, we have a problem, there is no bleed screw on the clutch master cylinder?

I've found this tricky to bleed up on my racer and was just about to replace the master and slave cylinder when someone gave me a good tip.  

Wedge the pedal right down to the bottom and leave over night, then bleed as normal the next day.  I am not sure quite why this works, something to do with small bubbles being able to make their way back out to reservoir.

This method worked first time for me...

Just as well as I had an event at the weekend!

LOL i think i may have a non standard master cylinder if there is no bleed screw on it.  Might just replace it anyway just to prevent further problems!

Title: Clutch setup
Post by: Henry Webster on January 18, 2006, 13:41:20

I don't think that they do necessarily have a bleed screw on the master cylinder.

Title: Clutch setup
Post by: Rangie3.0LtrDan on January 18, 2006, 14:16:24

It would seem they dont lol, i have bought a replacement and will test the old one tomorrow.  Is there a way of testing to see if the master cylinder is working ok?

Forgot to add as well, when doing over 60mph you cant change gear, the pedal loses all pressure, but it doesnt engage the clutch as you carry on going.  Try to change to fifth gear at 62mph and it just crunches until you get the speed back down to about 55mph.

Ok, have fitted the new clutch master cylinder.  Have tried bleeding it but am getting nothing.  The pedal is getting no pressure whatsoever.  It had a new pipe from the master cylinder to the plate on the chassis where it meets a flexi hose to go to the clutch camper to go to the slave cylinder.  It is now officially worse and i am pannicking somewhat as i cant use it!  There is no oil leaking from the pipe and the master cylinder is remaining full (it used very very small ammounts of fluid in the 40 mins we were pumping the clutch!

Anyhelp would be appreciated.  Also on this vehicle (j-reg 200tdi KA series vin) there is a hole in the bell housing at the bottom near the clutch front of the vehicle.  Is this sposed to be a drain hole?

when you fitted the master cylinder was the rod the right length? i only ask as i have had another vehicle that the rod on a new master cylinder was the wrong length and it wouldnt work properly as it was not pushing the piston in far enough?
the hole in the bell housing sounds like the hole where you put the wading plug when offroading

HTH

Heyup, well spoke to local land rover garage just now and they said i need to gravity bleed the system! lol, apparently it needs to get to the state where its flowing naturally lmao

Title: Clutch setup
Post by: Henry Webster on January 20, 2006, 15:27:28

Which is pretty much my point with leaving it overnight - have another read!

LOL i dunno, i dont understand these things lmao, am going to try and eezi bleed setup to push the fluid through and maybe that might help? has anyone got any views on this helping the gravity flow of the fluid?

Title: Clutch setup
Post by: Henry Webster on January 20, 2006, 16:43:44

No seriously, revist what I said earlier!  

I tried easi-bleeds, doing it manually again and again...  Left it overnight with the clutch pedal wedged down.  Came back to it the next morning and it bled straight up - no bother.  Pedal was spot on in seconds. Strange, but true.

I wouldn't have believed it, but the chap who told me is very knowledgeable and I trust him and he was right... :D

Was this with the bleed screw undone or done up?

Title: Clutch setup
Post by: Henry Webster on January 20, 2006, 17:13:56

So as you would whilst bleeding - push the pedal down with the bleed screw open - then wedge the pedal and do it up.

I don't suppose it is too critical as long as it is done up whilst you leave it.

Did it work then?

Post by: Rangie3.0LtrDan on January 21, 2006, 19:11:54

dunno, tried other ways first, your idea wont work til monday, cos i wedged the pedal down with the bleed screw done up, will teach me to read first, so will try it tomorrow!

:wink:  i think by now i would have lost my temper with it and slung it in a bush  :lol:

Post by: Rangie3.0LtrDan on January 22, 2006, 13:42:36

Sorry Henry,

Your idea failed miserably! lol, i think the new master cylinder is faulty as its pushing air through the system but no liquid.  Connected an eezibleed kit to it and all it did was send out air, wasnt taking anything out of the reservoir!

Title: Clutch setup
Post by: Rangie3.0LtrDan on January 22, 2006, 15:11:12

Right, have gotten fluid flowing through the system with the pedal wedged down!  Still no pressure though  :?:

Title: Clutch setup
Post by: Rangie3.0LtrDan on January 23, 2006, 13:34:09

Anyone?

Title: Clutch setup
Post by: Henry Webster on January 23, 2006, 14:21:06

Now that you have fluid running through the system, you would expect it to bleed up properly.  We did it the manual way.
