Nsa (Neutral Selection Assist) Transmission Information - Victory Cross Roads Classic Service Manual

2012 - 2013 Transmission Information
• Before replacing any transmission component, it is
important to determine which gear set has been
used. Transmissions with back-cut gear dogs can
be identified by locating the cut v-groove around
the outer diameter of any gear.
CAUTION
2012-2013 back-cut gears should not be used in
conjunction with previous model year Victory
transmission gears.
• Transmissions with back-cut gears do not require
countershaft shimming upon reassembly.

TRANSMISSION & CRANKSHAFT
NSA (Neutral Selection Assist) Transmission
Information
• The NSA system assists the operator by preventing
the unwanted engagement of 2nd gear when trying
to locate neutral with the gear shifter. This system
also prevents shifting into second gear from a stop
when the vehicle is not moving forward.
• When the transmission is in first gear or neutral, not
rotating or rotating slowly, the ball bearings are
seated into pockets in the mainshaft, preventing 6th
gear from sliding on the mainshaft. As the
transmission speed increases in first gear,
centrifugal force pulls the three ball bearings into
pockets in the 6th gear, thus allowing the shift fork
to move the 6th gear to allow engagement into 2nd
gear.
Centrifugal force pulls ball bearings outward
allowing movement of the 6th gear.
