Gearbox And Clutch Issues

[LTHLRB]

Hey guys i recently changed my clutch. When i got the gearbox and driveline back together i found a strange problem, The master or slave cylinder shit itself. I bled the system and everything but it just doesnt work at all, Fluid is comming through but there is no hydraulic action. Would i have stuffed the seals? Or would i have stuffed the master or slave all together? Any help on what to do, or where to get new ones from that will be greatly appreciated.

Thanks Phill

Is there fluid coming out anywhere ? Is the new clutch a heavy duty unit ? Cause if it is the extra pressure plate pressure might of busted your clutch pedal box. You'll have to get underneath where the pedals are and check

ive checked everywhere, the only place fluid is comming out of is where the bleed nipples are when loosened. Its a 300kw brass button clutch.

How are you bleeding it?

Are you bleeding the master cylinder first, then the slave cylinder...?

[LTHLRB]

no i wasnt, i was bleeding slave first. Well now i hav the idea. Master first, Then slave, Then the tube near the slave... Am i right?

[Syphon]

I'd say at a guess that's the way to go, possibly bleed the tube before the slave though...

The 2 times I have ever bled a clutch, I had to start with the master as the fluid reservoir was empty filling with air, so before fluid would flow down to the slave, i needed to bleed the master.

Have someone pump the pedal a few times, then hold the pedal bout 3/4's of the way to the floor. Crack open the bleed point and then tighten up within a second or so. Repeat that process until there is no more air bubbles present. Then move on to the other bleed points. Use some clear tube such as the type you would use for bleeding brakes so you can see the air bubbles clearly. Make sure you keep topping the fluid reservoir up. If it runs dry during the bleeding process, your going to have to start at the beginning again

Why did you bleed the slave in the first place? Did you change the slave? My guess ( only a guess) is that you ran the master cyl dry, so you need to bleed that first. Once you bleed tha master make sure you dont run it dry again ( dont let the fluid go very low, keep refilling it ). Then open the bleed valve on the slave and wait until fluid comes out. Leave it open until all bubbles are gone and thats it.

If you want to you can close the bleed valve and have someone pump the pedal for you and while they are holding the pedal to the floor, open the valve but close it before fluid stops coming out, repeat that until no bubbles come out .

Hope you just needed a good bleed and didn't kill anything.

If for some reason you need a new clutch master I have one brand new from Nissan that I bought for my car. It turned out I didn't need one (it was a shagged box). PM me if req'd.

Good luck!
