 ====== Inspections ======
+A good way to get familiar with the transmission and how it works (after removal from the case) is to put the assembled transmission on the bench or even better in a vice, spin the clutch gear and shift through the gears and watch how it all works together. Plus it's neat to watch.

+See the GEAR section below and click on Gear Dog Damage: Inspection and Causes in the sub documents for drawings and an animation of transmission gear action. That will also help understanding how the transmission works. \\

 With some of these parts, finding imperfections and cracks requires more than just glancing at them for obvouos damage. \\

 These gears have a habit of cracking on the ID were the cross section changes thickness. \\
 Cleaning with some 2000 grit emery revealed the crack better in the Left pic below.

+If you look at them closely, you will see that the dog pockets are formed not machined.

Those sharp corners and the thin material create stress risers that encourage cracking. In contrast, look at the pockets on the same Andrews gear, it is machined and the corners are round. \\
