GENERAL INFORMATION
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.
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 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/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/cm
2
: 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/in
2
: 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.
mm : Millimeter. Unit of length in the metric system. 1 mm = approximately .040".
Nm : Newton meters.
OD : Outside diameter.
Ohm : The unit of electrical resistance opposing current flow.
oz .: Ounce/ounces.
Piston Clearance : Total distance between piston and cylinder wall.
psi .: Pounds per square inch.
PTO : Power take off.
PVT : Polaris Variable Transmission (Drive Clutch System)
qt .: Quart/quarts.
Regulator : Voltage regulator. Regulates battery charging system output at approx. 14.5 DCV as engine RPM increases.
Reservoir Tank : The fill tank in the liquid cooling system.
Resistance : In the mechanical sense, friction or load. In the electrical sense, ohms, resulting in energy conversion to heat.
RPM : Revolutions per minute.
Seized Piston : Galling of the sides of a piston. Usually there is a transfer of aluminum from the piston onto the cylinder wall.
Possible causes : 1) improper lubrication; 2) excessive temperatures; 3) insufficient piston clearance; 4) stuck piston rings.
Stator Plate : The plate mounted under the flywheel supporting the battery charging coils.
TDC : Top dead center. Piston's most outward travel from crankshaft.
Volt : The unit of measure for electrical pressure of electromotive force. Measured by a voltmeter in parallel with the circuit.
Watt: Unit of electrical power. Watts = amperes x volts.
WOT: Wide open throttle.
