Hey everyone.
Umm ive had my 33 for about 3 years now and i left it for a week then went to start it and notices there was no resistance in my clutch, and my foot sank to the floor. seeming as it was working last time i used it i was a little surprised.
Will i need a new clutch or is something just a little loose?
if i need a new clutch how much?
If its loose how do I tighten it?
cheers.
Joel

You should be looking at the hydraulics first. Check the fluid tank under the bonnet. It is a combined tank for clutch and brake but the clutch take-off is above the brake to ensure the brake has priority. If it is low, look for where it is leaking, both clutch and brake. You will need to fix the leak then refill the tank and bleed either or both the clutch and brake hydraulic circuits. If there is clutch fluid on the carpet under the pedals it is most likely clutch or brake master cylinder. Clutch slave cylinder is on top of the gearbox and difficult to get at. Brake slave cylinders are at each wheel plus a brake balance valve above the rear axle.

Too much information?

Good luck,

cool thanks!
The fluid was low to very low... ive topped it up.
how do i bleed the clutch?

Hi,

There is a small bleeding screw on the clutch slave cylinder located in the front of it. It is very close to the big hose that feeds the cylinder with fluid from the small reservoir.

You need to attach a small tube in the screw in order to collect old fliud and prevent it to ruin whatever it spills.

Hope this helps.

Regards,

Might be worth finding out why the fluid is low too Smile

ok so i unscrewed what i think is the bleeding valve small screw in awkward position under the reservoir. now what? a fair bit of fluid came out but it was just draining straight from the reservoir... is this right? now what?!
also having a hard time getting the small screw in the awkward position back in...Y?
thanks again for the help

Probably wrong screw.
This one he is telling you about is on clutch slave cyl.
And that one is fitted on engine, some 20-30cm to the left (from drivers view) of distributor.
I think it is 7 or 8mm, and it is beeding nipple, which means you don't need to unscrew it all the way off.

ok!
umm i think i might have some real probs now!
the screw i took out was not the right one! and the reason that it wont go back in is because a small piston or something has moved in the way. now i was informed that i can maybe rectify the problem by applying pressure to the break or something like that... but not too much pressure or ill get air im my break system.
Does anyone know what im talking about?!
any suggestions? how far do i push? do i push am i boned?

Hi,

You have unscrewed the wrong screw which is the one located in the middle of the brake cylinder (the one with the reservoir on top). Confused

This screw separates the two pistons inside the cylinder which are intended for the front / rear wheels ... Have you taken it out completely?

Regards,

i sure have... its not good is it

gritsop · Posted: Wed Jul 20, 2005 11:17 am Post subject:

Hi,

It's no good ... However you can release the pressure in the hydraulic system. You can undo the small bolt in the clutch cylinder and having the opportunity to press backwards the piston of the brake cylinder using the screw or using a screwdriver or something.

Just an opinion.

Regards

Hi

To locate the bleeding nipple, best option is to get a friend to push the clutch pedal, while you position yourself on the left side of the vehicle.
When pedal is pressed, the slave cylinder, actuates on a fork that engages/desengages the clutch. Its hard to see it, because is almost under the bulkhead. Wink

When you locate the moving fork, you will be also seing the bleeding nipple...Bleed it using a small tube and a reservoir, to avoid spilling the brake fluid. Sad

But WHY is your fluid level to low??? Shocked

This must be your bigger "headache", right now...If you dont find the leak, you will end up bleeding your clutch every week... Confused

When you locate the slave cylinder, take a look at the rubber that engages/desengages the fork... They usually fail, and cause your type of problem...

Hope this helps
