Did get the wrong Clutch short shaft? how do I clean?
Doing a clutch job because my stub shaft and disc splines are toast. From what I understand this is from the previous mechanic not using the special Porsche super dooper High temp grease. (I have since received some from Roger) I also have a rebuilt torque tube on its way from 928 Int. I will not be getting any core back because it's splines are damaged as well . I bought this new stub shaft part# 928.421.235.11 ( the black one in the picture (and it is shorter than what was removed)
1. Will this short clutch shaft work with my new discs and other corresponding parts? or is this only compatible with other No Longer Available parts?
2. The clamping sleeve has tac weld on it and I see some drilled weight balancing holes. Will this tac welds added weight mess up it's balancing enough to be concerned? (second pic). Or was this done at the factory and balanced afterwards?
Should I clean these clutch parts and if so what should be used? Naptha? , dawn dish washing liquid?
well thats not gonna work,
dude,...............
send it back for a refund,
or better yet frame it ,
as no one has any of these,
use acetone to remove any grease
brake cleaner will also work.
NOTE if the tack weld is broken it would be wise to get another tack,
snug the bolt into the clamp before tack
Looks like the short shaft i need is the one ending in .16 which had been superceeded to .17 ..so I think I'll just get the one from GB at Precision.
Thanks Stan, the weld is intact, and the rest of that clamp looks fine. Is it safe to assume this is a clamp for the clutch end of the Torque tube? Is there a clamp back by the tranny end?
see pics below:
I found this in my parts box from the previous "mechanic" Is this from the rear clamp? Whatever it's from it's broken and must still be at his shop. I hope this is not part of 5th gear or something demonstrating a much more serious problems.

That would be one of the three "leaves" from a 5th gear.
Well then this is very bad news. My transmission seemed fine before, my "mechanic" looked into my clutch noise and and removed the torque tube and complete exhaust to get to the discs. Is this kind of break likely from the TT not being supported while coming out? Can one replace 5th gear? or am I looking at a whole transmission purchase?

Sunset does show your 5th gear as still available, but they don't always get NLA stuff marked accordingly until someone tries to buy it. $1600! Fingers crossed that those fragments aren't yours. 928 Int'l shows a used set for $500.
Ok , so it looks like I need a new 5th gear. I can't imagine the labor hours to put that in is cheap. not to mention other WYAiT' once he's in there. things like synchros and maybe others. Maybe I'll see if Greg B has any NOS transmissions left. Anyone know the hours labor required to replace just 5th gear?

Your shaft splines at the rear are toast, which indicates that your rear clamp bolt has been loose for a long time. A consequence of that constant movement, is that you get cracks which start at the base of the 'leaves', which will eventually progress and cause the leaves to fracture right through. This is the consequence that all 5 speed owners should be aware of, and concerned about, if that rear clamp bolt is not regularly torqued/replaced. (bold just to provide an alert for other 5 speed owners)
Lack of support of the TT when removing can cause that problem in isolation with an otherwise good shaft/5th gear, but I'd say from the look of the splines that the 5th gear input was shot anyway. When you get to look at it you're likely to see fractures at the base of the other two leaves.
Obviously that 'mechanic' didn't know what he was doing, and was deceptive in not alerting you to the failed 5th gear hollow input shaft.

Wow.
You've got quite the mess!
What year is your car....it doesn't show up on my phone.
