Transmission grind, slave adjustment?

[jersey280]

Hey guys,

 

Recently fixed all my issues with getting my 1976 280z L28 4sp running! In the process I replaced the slave and master clutch cylinder and bled them. Only remaining issue is that occasionally when press the clutch in, and I attempt to put the car into gear it will grind. If i release and attempt again, it goes in no problem and drives fine. I am doubting I have a transmission issue and am leaning more towards the slave possibly not extending far enough to cause proper engagement. Has anyone experienced this? Any things I should check to ensure I don't have a larger issue? Any help greatly appreciated. Thanks!

The red above would be what's called pumping up the system.  Air in the system is overcome by pumping.  The hydraulic system is essentially self-adjusting if the mechanical parts are correctly adjusted.  There's no adjustment at the slave cylinder.

 

I'd check the play at the pedal first, especially since you installed a new MC.  You can adjust the rod out without removing anything, just use pliers and twist it in place.  And rebleed to remove all air traces.  You might have a small amount of air and too much mechanical play.

Thanks again zed. I will try it out and post the results.

Yep if you have to pump it, there is air in there and it needs to be bled again.
