930 transaxle experts out there?, My guide tube and T.O. bearing are toast! Options

[wbergtho]

I have less than a 1000 miles on a new 930 box and clutch. The T.O. bearing seems dry and toasty and the guide tube looks well worn and "lumpy" on one side only. I may have had preload on the T.O. bearing when i first set the trans up and drove 200-300 miles. I eventually went to a hydraulic clutch and allowed a small air gap @ the slave to prevent preloading the T.O bearing. It apparently doesn't take long to toast these parts. I'm hoping my box is still fine.

Anyone with any experience (good/bad)...please chime in. For now, I believe I will replace these parts...cross my fingers...and reassemble. This is becoming such a pain in the ass...that I'm no longer having any f--- (IMG:style_emoticons/default/smash.gif) (IMG:style_emoticons/default/dry.gif) ing fun with this car. It's just a dreaded feeling to drive it...knowing that I'll be putting it up on jack stands to repair and spend more godamn money!

Bill,
I went through a similar situation, I too preloaded the T/O bearing for a time and did some damage to my guide tube. I think having the pre-load held the T/O against the guide tube and caused the marks. The key is free-play, once I gained some things seem to be working well. Consider your self a bit lucky, before I learned I trashed the thrust bearing in my engine. I had to do a lower-end rebuild before addressing the clutch issue. I also set up some springs to help keep everything balanced concerning the clutch fork.
One spring keeps the free-play gap when the clutch is engaged and the other balances the weight of the heavier fork body and slave system. I also make sure the clutch pedal is held away from applying any pressure on the system at rest. I've felt your pain (IMG:style_emoticons/default/smash.gif)
