Thanks for all the information. I ended up replacing the clutch/pressure plate/throwout bearing over the course of a long weekend. The problem was pretty much as Ozark Lee describes on Matthewsvolvosite. The "fingers" on the pressure plate were worn down so much the throwout bearing could not push the pressure plate far enough to disengage the clutch adequately. Also the cage that holds the pressure plate and springs together was partially broken. I used the instrutions from alldatadiy.com. They were pretty good. The three tips that others have mentioned were very helpful:
1. Remove the frame that the engine is mounted to entirely for better access
2. Remove the fan
3. Cut the heads off of two approx. 5 inch bolts that fit in the holes that mount trans to motor, one on either side to act as guides as you bring the trans and motor back together
4. When purging the clutch slave cylinder line after you have put it back together be sure to keep the brake reservoir completely full as is is very diffiult to see the clutch slave cylinder reservoir since to partially shares the brake reservoir but is mounted behind the the brake reservoir
Thanks again for all the input, She running perfectly again.
