MAINTENANCE
Extended Storage
Bearings
Grease jackshaft and drive shaft clutch side bearings with a high
quality bearing grease to prevent corrosion.
Clutch and Drive System
Remove drive belt and store in cool dry location. Lubricate sheave
faces of drive and driven clutches with a light coat of oil or Polaris
Cable Lubricant (PN 2870510). Do not lubricate clutch components
except driven clutch shaft bushing as outlined in Master Repair
Manual. See your dealer.
Engine and Carburetor Protection
Proper preparation of the engine and fuel system is vital to the
prevention of rust and corrosion on precision engine parts during
storage. Whenever the machine is stored for a period of more than 60
days,the engine must be fogged (Polaris PN 2870791). Follow the
engine fogging instructions provided on the can.
Always add a fuel conditioner/stabilizer or Premium Carbon Clean (PN
2871326) to the fuel tank. Follow the instructions on the can, running
the engine for five minutes to get additives through the entire fuel
system. Top off with fresh fuel.
HINT: For easier starting after extended storage, add lubricant to the
fuel in the tank at a 40:1 ratio and run the engine for three to five
minutes before storage. This will lubricate the fuel pump diaphragm to
keep it flexible and help prevent loss of prime.
If stabilizer is not used, drain the carburetors by removing the water
trap drain plugs (see page 126). Catch fuel in a container or shop cloth.
Reinstall plugs securely. Observe all fire safety rules when draining
carburetors. See gasoline warnings on page 90.
Jet restriction caused by improper storage can cause lean conditions
and very poor slow speed driving quality.
