[DeTomaso] third update on clutch slave not compressing fully

[Asa Jay Laughton]

But you need to disengage it all.  For all you really know, unless 
you've disconnected that linkage, when you are pounding the piston back 
in, you may be hammering something in the bellhousing and -not- the 
slave cylinder.  By disconnecting the linkage you can verify the 
bellcrank lever moves smoothly when not engaging the clutch.  That will 
isolate it from the hydraulic system.

If the bellcrank lever moves as expected, then you need to start looking 
at the rest of the system, slave, master, lines in between, age of 
fluid, etc.

OH, and there is absolutely NO reason you should have to "hammer" the 
slave piston back in.  It should move smoothly by -hand-, albeit with a 
little bit of umph.  If it's more than you can move by hand... something 
is wrong, you need to disconnect and isolate the individual systems.

So I can push the rod perpendicular to it's axis and feel and see it moving around when it's not under tension and play exists. When there is play the clutch arm moves easily.
