Ever have one of those days? I was hoping to get the engine in my Bird fired up this week after having the car apart for too many years. Went to tighten the left rear wheel after replacing the rear axle seal. Car was rolling so I put it in gear. Still rolling. After much investigation I determined that when I installed the large input toploader and reused the slightly used 11" diaphragm pressure plate I created a problem. The front bearing retainer that the throwout bearing rides on is too large in diameter to go through the pressure plate fingers. When I bolted it together it pushed the fingers foreward and effectively permanently disengaged the clutch. The only practical way to get the clutch out on the Bird is to pull the engine and trans as a unit. Got the drive shaft, shift linkage, and transmission mount out. Need to continue taking off parts and pull the engine. I should have caught this on assembly but not something I ever dreamed of and wasn't looking for that particular problem. Why do I mess with this stuff?
