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.

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

: 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

: 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".

N-m: 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.
