Clutch Bleeding Question


Recommended Posts

Hi guys,

 

Just have a quick question.

Have just finished a 5 speed swap on my RHD 73 2002, and I have just had a go at bleeding the clutch manually but it doesn't seem to want to work. 

After about 20-30 minutes of bleeding I can get clutch pressure after about 15-20 pumps of the pedal but thats it. 

Just wanting to know if theres something I've done wrong? Was thinking I might have to change the master cylinder to match the 5 speed one in size but I've never read anything about anyone doing that in any posts. Anyone have any suggestions? 

 

I appreciate any information, thank you for your time.

 

Arlo.

make sure to bleed the master cylinder. Since there is no bleed nipple, you have to pump the clutch a few times, crack the outlet as someone else is pushing the peddle down, then tighten it back up before they let it up. Then bleed the slave cylinder.

Make sure you didn't install the slave cylinder upside down. The bleed nipple should be on the bottom....and use thread sealant on the nipple threads.

If you have the master upside- right (does it need to be upside- down in Oz?)  with the bleeder pointed DOWN as Armin says,

then the clutch should, eventually, self- bleed if you get ANYTHING out of it.

 

Stompety- stomp- stomp- stomp often does it.  I learnt that out of frustration one day.

 

No, the master's sized about right.

Sorry to drag up this old chestnut !!

 

But, I am struggling to gain any pressure on my pedal.  I am guessing when you say to pump the pedal Toby, you mean with the nipple closed on the slave ?

 

I have tried manual bleeding with someone pushing the pedal while I open the nipple and with a pressure kit, but I'm still not getting a pedal !!  Any suggestions ?

You haven't got the slave cylinder installed upside down with the bleed screw at the bottom? I think 5 speeds are particularly bad for this.

I was 50/50 and got it wrong. Ignore me.

 

It still seems slightly counter productive as you would think having the bleed screw at the top would help getting the air out.

If you look at the angle of the bleeder you can see that when it is facing down it is actually drawing from the top of the slave, if you take the bleeder out and look inside you can see where it pulls from.  If I was an artist I would draw a picture because it is hard to explain but I aint got no art skills.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
