GENERAL INFORMATION
Glossary Of Terms
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 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. The common method used to convert mechanical energy to electrical energy in the battery charging coil,
ignition generating coils, and ignition trigger (pulse) coil.
mi.:
Mile/miles.
mm:
Millimeter. Unit of length in the metric system. 1mm = .040
″
.
N-m:
Newton meters.
OD:
Outside diameter.
Ohm:
The unit of electrical resistance opposing current flow.
oz.:
Ounce/ounces.
Piston Clearance:
Total difference between piston outside diameter and cylinder inside diameter.
Piston Erosion:
Piston dome melts. Usually occurs at the exhaust port area. Possible causes: 1) Detonation due to
lean fuel/air mixture, improper spark plug heat range, excess heat buildup, poor fuel quality / octane rating.
Pre-Ignition:
A problem in combustion where the fuel/air mixture is ignited before normal spark ignition. Piston looks
melted at area of damage. Possible causes: 1) incorrect spark plug heat range; 2) spark plug not properly torqued; 3)
“glowing” piece of head gasket, metal burr or carbon in the combustion chamber; 4) lean fuel/air mixture.
Primary Circuit:
This circuit is responsible for the voltage build up in the CDI capacitor. In the CDI system the parts
include the exciter coil, the trigger coil (pulse coil), the wires from stator plate to CDI box and to the low resistance
primary windings in the ignition coil.
Primary Clutch:
Drive clutch on engine. Mainly RPM sensitive.
psi.:
Pounds per square inch.
PTO:
Power take off.
PVT:
Polaris Variable Transmission (Drive Clutch System)
qt.:
Quart/quarts.
RPM:
Revolutions per minute.
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.
Running Time:
Ignition timing when fully advanced or at specified RPM.
Secondary Circuit:
This circuit consists of the large secondary coil windings, high tension wire and ground through the
spark plug air gap.
Secondary Clutch: (Also-Driven Clutch)
The torque sensitive clutch in a CVT system which is located on the
transmission input shaft.
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;
Spark Plug Reach:
Length of threaded portion of spark plug. Polaris uses 3/4
″
(2 cm) reach plugs.
Static Timing:
Ignition timing when engine is at zero RPM.
Stator Plate:
The plate mounted under the flywheel supporting the primary ignition components and lighting coil.
