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 : Centrifugal 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.
Electrical Short : Short circuit. An electrical circuit that 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/feet.
Foot Pound: Ft. lb. 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.
Inch Pound
: In. lb. 12 in. lbs. = 1 ft. lb.
kg/cm2 : Kilograms per square centimeter.
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/in2 : Pounds per square inch.
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.
