Slave or Master?

[PlumCrazy]

I just bought a 4.0 with a M50d. The PO had just had a new clutch, slave,trow-out bearing and pressure plate replaced. I figured they just didnt know how to bleed a Ranger master cyl. So I pulled the master out with the reservoir and quick disconnect line and I bled it so that no air would be trapped in the master. I put it all back together and then I bled the slave.

Even after all that I still have to push the pedal to the absolute floor to get anything out of it. Sometimes it will disengage completely, and then sometimes I have to hold the brake and clutch at the same time to keep the truck from driving forward. It is almost always a pain to get it i first or reverse.

I am assuming that since the slave is new, the master must be the prob, but I if I pop the quick disconnect apart and push the clutch it is solid, there is no travel at all, so I know that fluid isnt getting around the piston (not mention there is no fluid on the floor). And I almost forgot to mention that I am not losing and fluid.

So now you guys all know my dilemma, let me know what you guys think.

It sounds to me all of the air isn't out of the slave.

Thats what I have been thinking. I didn't use a clear hose when I bled it, I just bled it until there was steady stream squirting out. I was planning on bleeding it again when I go home this weekend.

Clear hose off the bleeder back up to the reservoir, unbolt the master, tilt it upwards in the firewall and hand pump it through the fire wall. You need to tilt it to get the air out of it....helps if your front end is up on ramps too. Keep pumping till the hose runs clean with no bubbles. This is the best way to do this job. Good luck.

I'm guessin the slave cylinder. Because mine went out and sometimes did exactly what you were sayin

Bleed it the way i said first....it cant hurt to try. Air in the lines will do the same thing, and since the slave is new and you dont see any fluid in the bell housing i would bet on it being improperly bled. Bench bleeding does not work well with this system.

This isnt my first rodeo with this system, I have done four clutch/slave jobs on Rangers in the last year. I normally just unbolt the master and leave it hooked to the pedal so I can pump it horizontally. but that was on the bolt on type masters, this twist lock type master wont allow me to do that. I was able to bench bleed the master and line successfully the check valve on the quick disconnect make it pretty easy. I am going to bleed the slave again and see if I get any air out of it. Im pretty sure thats where the air is.

Problem solved, I rebled the slave and now it drops right into gear. I am pretty sure the shifter bushinga are a little worn though, because sometimes its a little tricky to find 4th.
