Deep gouges in slave, prop shaft play... TT rebuild time?
As the title says, was prepping to swap my new slave cylinder in the car before I put the new motor and clutch in my 07 Z06 so just for ***** and giggles I took apart the currently installed slave. Found deep gouges on the top and bottom of the cylinder. Noticed that the front end of the prop shaft has up/down side/side play. Do these symptoms jump out at any of you to what has failed? Am I due for a torque tube rebuild? Car was a stock 07 Z06 before the tear down. Clutch was VERY warn, and I was getting a pedal stuck half way down issue before the tear down. Any help is appreciated, thanks in advance.
Yes, TT bearing rebuild (may as well do the couplers while you are in there) and slave needs to be replaced as well.
On the new slave, change the plastic TB race with the billet one.
Also, what does the Pilot bearing surface look like on the front of the input shaft, since if gouged/worn to hell, or spines peen to hell, replace it at the same time as well.
Also, if running a tick master cylinder, make sure you have it adjusted correctly, so the TB is not begin over thrown to cause the pressure plate fingers to be over compressed. Hence looks like what caused the damage to the slave in the first place (short of a LS9 clutch exploding, since the non removable pressure plate love to do that when over stressed).

Hey man! I know this was about a year ago but where did you get that prop shaft? The middle ring on mine and a small area behind the splines was chewed up because of a bellhousing failure, and I can’t seem to find a new prop shaft anywhere.
Slave cylinder is trashed and needs to be replaced, but if the spines and snout of the TT input shaft are still fine, little lathing and clean up on the inner surface band ring will have the old unit right as rain again.
Hence the band is there just in cause the pilot bearing goes south, to bounce that ring off the ID off the slave only, to keep the unit still kind of working. Its not a normal contact area when all it right with the parts isntead.
Also, if spines can be cleaned up, and its just the snot that has a little wear/marring that can not be cleaned up without reducing the OD of it, then check around for a shop that can spray weld to rebuild up the snout OD surface. The input shafts are in high demand/limited supplies, and have seen them listed for over $400 new currently from the dealers that do have the in stock.
Hey thanks for the quick response! I didnt even see it last night haha. I already got a new slave and rebuild kit, my concern was the purpose of the ring, and if it rubbed that much the prop shaft or other pieces may be bent now...My bellhousing snapped and i imagine that caused flex and stress on the torque tube which caused what I attached.
Also I dont have access to a lathe to see how true it is. I found a whole assembly with bellhousing (my original issue lol) for 1200 with 22k miles just to get the car back on the road, then ill have a spare rebuild kit for when it happens again hahah. Ill look around for someone who can build and true that back up for next time if theyre such a hot commodity. SO I guess Ill have a really nice clutch alignment tool for the time being!
