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.
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.
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.
Left 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. 1mm = 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.
qt.:
Quart/quarts.
RPM:
Revolutions per minute.
Regulator:
Voltage regulator. Regulates battery charging system output at approx. 14.5 DCV as engine RPM increases.
Resistance:
In the mechanical sense, friction or load. In the electrical sense, ohms. Both result in energy
conversion to heat.
Right Side:
Always referred to based on normal operating position of the driver.
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.
