When I reinstalled the clutch on my g50 -03 everything when to plan but when I had the tranny within a 1/4 of an inch or less from mating up to the adapter plate it would go no further. I got my head up my tail pipe and brought it home with the tranny bolts. When I put it on the dyno it slipped at high power settings, all other aspects of operation were normal. Now I am taking it apart to see what is wrong. As a side note this clutch combination has run in the car before with no issues at all. The first thing I looked at was free play on the clutch arm with the slave cylinder removed. There is free play of about a 1/4 inch. When I mount the slave cylinder the push rod against the clutch arm is compressed about 3/4 of an inch for the fasteners to mate up. What am I missing? lee
Since posting the tranny has been in and out. The clutch was installed with an alignment tool. When i got the clutch out took it to a friend who builds hi po clutches. We tested the pressure plate and it tested to the Porsche spec of 850 lbs. The clutch showed some signs of glasing kind of shiny instead of a dull surface. Changed the plate and disc because I had a pressure plate in hand, put it back together and all is well. What I learned from this is that Porsche clutches have way more pressure than stock Chevy and my friend strongly suggested to always start the car in neutral with the clutch out to avoid dry starts with lots of pressure on the thrust bearing. probably a good practice on any car just something that I had developed as a bad habit over the years.
