The GOOD: Heavy Duty Transmission Door

 All the transmission gears look good and spin freely.  No chips or nicks on initial inspection.

 . . . and special Center Case Bolt.  The big bore cylinders (and bored cases) require a modified bolt to clear the larger cylinder spigots.  All looks ok . . .
The BAD: The No. 2 ,3 and 4 cam bearings(case side) are toast (lost many rollers which went through the breather and were in the lower end).  I picked at the rollers and they easily just fell out.

This motor was ready for a redo . . .
