Glossary Of Terms

ABDC: After bottom dead center.
ACV: Alternating current voltage.
Alternator: Electrical generator producing voltage
alternating current.
ATDC: After top dead center.
BBDC: Before bottom dead center.
BDC: Bottom dead center.
BTDC: Before top dead center.
CC: Cubic centimeters.
Center Distance: Distance between center of crankshaft
and center of driven clutch shaft.
Chain Pitch: Distance between chain link pins (No. 35 =
3/8" or 1 cm). Polaris measures chain length in number of
pitches.
CI: Cubic inches.
Clutch Buttons: Plastic bushings which aid rotation of the
movable sheave in the drive and driven clutch.
Clutch Offset: Drive and driven clutches are offset so that
drive belt will stay nearly straight as it moves along the
clutch face.
Clutch Weights: Three levers in the drive clutch which
relative to their weight, profile and engine RPM cause the
drive clutch to close and grip the drive belt.
Crankshaft Run-Out: Run-out or "bend" of crankshaft
measured with a dial indicator while crankshaft is
supported between centers on V blocks or resting in
crankcase. Measure at various points especially at PTO.
CVT: Continuously Variable Transmission (Drive Clutch
System)
DCV: Direct current voltage.
Dial Bore Gauge: A cylinder measuring instrument which
uses a dial indicator. Good for showing taper and out-of-
round in the cylinder bore.
Electrical Open: Open circuit. An electrical circuit which
isn't complete.
2.8
Electrical Short: Short circuit. An electrical circuit which
is completed before the current reaches the intended load.
(i.e. a bare wire touching the chassis).
End Seals: Rubber seals at each end of the crankshaft.
Engagement RPM: Engine RPM at which the drive clutch
engages to make contact with the drive belt.
ft.: Foot or feet.
ft-lb: (foot pounds) A force of one pound at the end of a
lever one foot in length, applied in a rotational direction.
g: Gram. Unit of weight in the metric system.
gal.: Gallon.
ID: Inside diameter.
in.: Inch/inches.
in-lb: (inch pounds) A force of one pound at the end of a
lever one foot in length, applied in a rotational direction. 12
in. lbs. = 1 ft. lb.
kg/cm
kg-m: Kilogram meters.
Kilogram/meter: A force of one kilogram at the end of a
lever one meter in length, applied in a rotational direction.
l or ltr: Liter.
lbs/in
Left or Right Side: Always referred to based on normal
operating position of the driver.
m: Meter/meters.
Mag: Magneto.
Magnetic Induction: As a conductor (coil) is moved
through a magnetic field, a voltage will be generated in the
windings. Mechanical energy is converted to electrical
energy in the stator.
mi.: Mile/miles.
mm: Millimeter. Unit of length in the metric system. 1 mm
= approximately .040".
N-m: Newton meters.
