GENERAL INFORMATION

Service Tips

In order to perform service work efficiently and to prevent costly errors, the technician should read the text in this

manual, thoroughly familiarizing him/herself with procedures before beginning. Pictures and illustrations have

been included with the text as an aid. Notes, cautions and warnings have also been included for clarification of text

and safety concerns. However, a knowledge of mechanical theory, tool use and shop procedures is necessary to

perform the service work safely and satisfactorily. Use only genuine Polaris service parts.

Cleanliness of parts and tools as well as the work area is of primary importance. Dirt and foreign matter will act

as an abrasive and cause damage to precision parts. Clean the vehicle before beginning service. Clean new parts

before installing.

Watch for sharp edges which can cause personal injury. Protect hands with gloves when working with sharp

components.

If difficulty is encountered in removing or installing a component, look to see if a cause for the difficulty can be

found. If it is necessary to tap the part into place, use a soft face hammer and tap lightly.

Some of the fasteners were installed with locking agents. Use of impact drivers or wrenches will help avoid

damage to fasteners.

Always follow torque specifications as outlined throughout this manual. Incorrect torquing may lead to serious

machine damage or, as in the case of steering components, can result in injury or death for the rider(s).

If a torquing sequence is indicated for nuts, bolts or screws, start all fasteners in their holes and hand tighten.

Then, following the method and sequence indicated in this manual, tighten evenly to the specified torque value.

When removing nuts, bolts or screws from a part with several fasteners, loosen them all about 1/4 turn before

removing them.

If the condition of any gasket or O-Ring is in question, replace it with a new one. Be sure the mating surfaces

around the gasket are clean and smooth in order to avoid leaks.

Some procedures will require removal of retaining rings or clips. Because removal weakens and deforms

these parts, they should always be replaced with new parts. When installing new retaining rings and clips use care

not to expand or compress them beyond what is required for installation.

Because removal damages seals, replace any oil or grease seals removed with new parts.

Polaris recommends the use of Polaris lubricants and greases, which have been specially formulated for the

top performance and best protection of our machines. In some applications, such as the engine, warranty

coverage may become void if other brands are substituted.

Grease should be cleaned from parts and fresh grease applied before reassembly of components.

Deteriorating grease loses lubricity and may contain abrasive foreign matter.

Whenever removing or reinstalling batteries, care should be taken to avoid the possibility of explosion

resulting in serious burns. Always disconnect the negative (black) cable first and reconnect it last. Battery

electrolyte contains sulfuric acid and is poisonous! Serious burns can result from contact with the skin, eyes or

clothing. ANTIDOTE: External - Flush with water. Internal - Drink large quantities or water or milk. Follow with

milk of magnesia, beaten egg, or vegetable oil. Call physician immediately. Eyes - Flush with water for 15 minutes

and get prompt medical attention.

clutch.

ClutchOffset: Drive and driven clutches are offset so that drive belt will stay nearly straight as it moves along the clutch

face.

Clutch W eights: Three levers in the drive clutch which relative to their weight, profile and engine RPM cause the drive

clutch to close.

Condenser/Capacitor: A storage reservoir for electricity, used in both E.T. and CDI systems.

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 lower half of crankcase. Measure at various points especially at PTO.

Maximum allowable run-out is .006″ (.02 cm).

DCV: Direct current voltage.

Detonation: The spontaneous ignition of the unburned fuel/air mixture after normal spark ignition. Piston looks

“hammered” through, rough appearance around hole. Possible causes: 1) too high a compression ratio for the fuel

octane; 2) low octane fuel; 3) over-advanced ignition timing.

Dial Bore Gauge: A cylinder measuring instrument which uses a dial indicator. Good for showing taper and

out-of-round in the cylinder bore.

Driven Clutch: (Also-Secondary Clutch). The torque sensitive clutch in a CVT system which is located on the

transmission input shaft.

Electrical Open: Open circuit. An electrical circuit which isn’t complete. (i.e. poor connections or broken wire at hi-lo

beam switch resulting in loss of headlights.

Electrical Short: Short circuit. An electrical circuit which is completed before the current reaches the intended

component. (i.e. a bare wire touching the grounded 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.

EBS: Engine Braking System

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.

Head Volume: Cylinder head capacity in cc, head removed from engine with spark plug installed.

High Tension Lead: The heavy insulated wire which carries the high secondary voltage from the coil to the spark plug.

HoledPiston: Piston in which a hole has formed on the dome. Possible causes: Lean mixture; Incorrect ignition timing

HP: Horsepower.

ID: Inside diameter.

IgnitionCoil: A type of transformer which increases voltage in the primary windings (approx. 200V) to a higher voltage

in the secondary windings (approx. 14KV - 32KV) through induction. Secondary voltage is high enough to ionize (jump)

the air gap at the spark plug.

Ignition GeneratingCoil: Exciter coil, primary charge coil. Stator plate coil which generates primary ignition voltage.

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.

SecondaryCircuit: 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.

SeizedPiston: 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.

TDC: Top dead center. Piston’s most outward travel from crankshaft.

Trigger Coil: Pulser coil. Generates the voltage for triggering (closing) the thyristor and timing the spark in CDI

systems. Small coil mounted at the top of the stator plate next to the ignition generating coil.

Voltage Regulator: Maintains Prevents over-charging of battery or damage to electrical components as engine RPM

increases.

V enturi: An area of air constriction. A venturi is used in carburetors to speed up air flow which lowers pressure in venturi

to below atmospheric pressure, causing fuel to be pushed through jets, etc., and into the venturi to be mixed with air and

form a combustible air/fuel mixture.

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.
