bleeding clutch
 

I am near the end of my manual tranny swap and need to bleed the hydraulic clutch. What is the best way to do this? Everything is new, master, slave and hydraulic line. The pump/bleed method is not working. Any help is appreciated. I would like to get this done tomorrow. This is on my 86 K5 w/ 87 parts (should be the same).

Been there myself. Take it out and bench bleed it. Total pain otherwise.

Re: bleeding clutch
 

Agreed, MUCH faster to do out of the truck.

after going thro this myself and asking every one the had one of these trucks i got pissed. but it in to get the lines right then pull it out and bleed it. its to much of an angle to get the air out in the truck you will have to turn eveything to mive the air. also do not worrie about reseting the slave till the vary end. bleed it like its dead headed once its rick hard with zero play then reset the slave. its the only way that is 100% that i have found

Re: bleeding clutch
 

Thanks. Going to remove shortly.

Re: bleeding clutch
 

how do you reset the slave? push the plunger all the way back?

Re: bleeding clutch
 

best way is to take the slave loose, and slowly push it in and out. more volume in the slave. thats how we do all our cummins conversions.

Re: bleeding clutch
 

sometimes to reset the slave i open the bleeder with the pushrodin the slave as i push against the bench or what ever then close it back up. other times it will push in with some force

Re: bleeding clutch
 

ok i didnt know this trick, thanx i will try it when needed

Re: bleeding clutch
 

Well, this was the easiest I have ever bled a clutch. me and my son had it done in 5 minutes, so much easier with the master and slave on the bench. Thanks.

Re: bleeding clutch
 

no problem. i had might fight with the clutch back when i got my c20. time wasted is no fun

Re: bleeding clutch
 

Can anybody explain "setting the slave" again, I guess I am dense. I have already put the assembly in the truck and it will engage/disengage the clutch, but the clutch does not grab until almost all the way out. I know that is wrong. Thanks,

Jim

Re: bleeding clutch
 

see how much travel you have at the fork. think its 3 inch??? or about there if a remember right. then go form there. i can relook at mine to see what it is tomorrow after work if you need. but do no they grab some low and mine is all out but the last 1 inch. not much play.

I think my throw out bearing is always touching the pressure plate.

Re: bleeding clutch
 

what makes you think that?

Re: bleeding clutch
 

In 1st gear, I should be able to get the truck moving with no throttle, but the blazer does not move until the clutch pedal is almost up. I will get under therear tomorrow after work and check.
