Primary Driven Gear - Suzuki GZ250 Marauder Service Manual

GEARSHIFT FORKS
Measure the gearshift fork clearance in the groove of its
respective gear using the thickness gauge. The clearance for
each of the two gears hift forks plays an import ant role in the
smoothness and positiveness of the shifting action. Each fork
has its prongs fitted into the annu lar groove provided in its
gear. During operation there is sliding contact between the
fork and gear and, when a shifting action is initiated, the fork
pushes t he gear axially. If the clearanc e is too great, the
meshed gears may slip apart.
If the clearance exceeds the specification, replace the fork, its
respective gear or both.

• Remove the oil pump drive gear
If the internal damper wears, play is generated between
gear and housing, causing abnormal noise. If the play is
extreme, replace the primary driven gear assembly with a
new one.
