GEARCASE COVER AND CAM GEARS
 
GENERAL
 
Read the complete gearcase section carefully before you
begin any service work.
For the gearcase components to operate at their optimum, all
components must be properly fitted and matched. Changing
one component can affect many others. It is important to
know and understand all inspection procedures and how
components interact.
