the Gearcase lets review the rotating gears that make
up the gearcase. Additional details follow for servicing
each of these gears.
e Attachment Hub Bevel Gear- This gear is located
in the Transmission Housing and can be removed by
hand from the Transmission Housing for inspection.
e Bevel Gear- This is the top gear on the Planetary
Shaft. The Bevel Gear is held to the Planetary Shaft
with a Snap-Ring. This Snap-Ring must be removed
