clutch housing cracked

Happened in town. Was able to drive home shifting without the clutch. If the clutch was depressed the engine died.
Had it apart in short time. A used one complete coming from Larry at APES.

that's bad!! What happened? Broken flex disc (rear one)??

I broke one housing a couple of years ago due to a bad rear flex disc.

There was a discussion about this failure on race cars a few years ago. I'm pretty sure that Greg Seferian was in on it.

From eman911 in the link provided by Ed:

Be sure to check for proper fit when replacing the rear giubo. I have found the center bushings in the replacement units to have too small an ID , thus not allowing the stub on the input flange to seat and center properly. A little gentle work with a dremel tool and sanding drum fixed things up nicely.




My gwee-bos have all been replaced by the PO. I replaced the center support.

On close inspection, it appears the rear gwee-bo only accepts about half o the pilot shaft of the clutch housing?

How do I tell?

Mine appears to be a late model 4 cylinder cover. 78 Sport Sedan.

The shaft on the clutch that goes through the housing will either be straight between the flywheel and the yoke end or it will have a taper.

Post a picture of it and I can tell you.

I'm guessing tapered. Front bearing is smaller than the rear.

You have the tapered one. Which is the later version.

One thing you need to do is get rid of the yoke nut and go to the updated version which is the double nuts that were used on the GTV-6's and the Milano's.

The nut you have is original and they were a one time use nut and were well known for coming loose.

everything in mine was tight, except the front bearing slides on to the shaft and right off by hand. Weird. I'm concerned about the guibo where it mates to the shaft. I'll fiddle with it in the morning.

This is a GOOD helpful thread. Thanks to all those posting. I'm learning stuff I did not know. These are good cars and need the advice of those that know.
