Re: [DML] CLUTCH BLEEDING

Mike,
 
Don't worry about the adjustable clutch linkage, you very likely won't need it at all with the new clutch line installed.
 
I've had the same problem with used slave cylinders and bleeding.  I think I used a small paper clip and dental pick to clean up the bleeder screw and it fixed it right up.  You might want to also clean up the bleeder screw hole on the cylinder while you've got it off.  It's a amazing that a little obstruction can make such a big difference.
 
Good luck,

Subject: [DML] CLUTCH BLEEDING


History----- Josh's car is running fairly good, so I tackled the clutch. When first starting up, it shifts smoothly in all gears. After about 5 minutes, it wants to grind going into reverse. After it gets up to operating temperature, it wants to grind going into both reverse and 1st gear. Yes, I know about the adjustable clutch fork and that next on my agenda.

I have rebuilt the master cylinder and the slave cylinder. Both check 4.0 on the bench. I decided to replace the original plastic line that runs through the frame. I accomplished this and replaced it with metal line, so now it is all metal from the master to the slave.

Now here's what has me stuck. I cannot get the system to bleed correctly either by pumping the pedal or by using a hand vacuum pump. After two hours of pumping the pedal and vacuuming, all I got out was about a 1/4 cup of fluid. Here's the odd part, with the bleed screw open, when the pedal is pushed, the clutch fork moves almost full throw and almost no fluid comes out. I decided that maybe the bleed screw itself might be plugged, so I took it out and installed a good spare. The original was clean and open. I then went to reinstall the one I took out and by the time I had it reinstalled (maybe 3-4 minutes). I noticed fluid dripping from under the engine. It was brake fluid of course, so I checked the reservoir and I had lost 3/4 of the bottle out the bleed screw hole while I was doing my swap. This was either caused by gravity or a siphon effect.

My question is----why is the system not bleeding when the bleed screw is turned a 1/4 turn, yet, when I take it all the way out, it wants to pee everywhere?
