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 116). Catch fuel in a container or shop cloth. Reinstall plugs securely. Observe all fire safety rules when draining carburetors. See gasoline warnings on page 80. Jet restriction caused by improper storage can cause lean conditions and very poor slow speed driving quality. 150
