4 Torque Conversions (ft-lb/N-m) Drive Belt Break-In Procedure New drive belts require a break-in period of approximately 25 miles. During this period, drive the vehicle for 25 miles at 3/4 throttle or less while varying throttle position (but not exceeding 40 mph). By varying throttle position, the exposed cord on the side of a new belt will be conditioned allowing the drive belt to gain its optimum flexibility and will extend drive belt life. Gasoline - Oil - Lubricant RECOMMENDED GASOLINE The recommended gasoline to use is 87 minimum octane regular unleaded. In many areas, oxygenates are added to the gasoline. Oxygenated gasolines containing up to 10% ethanol or 5% methane are acceptable gasolines. When using ethanol blended gasoline, it is not necessary to add a gasoline antifreeze since ethanol will prevent the accumulation of moisture in the fuel system. RECOMMENDED ENGINE OIL The recommended oil to use is Arctic Cat ACX All Weather synthetic engine oil, which has been specifically formulated for use in this Arctic Cat engine. Although Arctic Cat ACX All Weather synthetic engine oil is the only oil recommended for use in this engine, use of any API certified SM 0W-40 oil is acceptable. OILCHARTJ RECOMMENDED FRONT DIFFERENTIAL LUBRICANT The recommended lubricant is Arctic Cat Gear Lube or an equivalent gear lube which is SAE approved 80W-90 hypoid. This lubricant meets all of the lubrication requirements of the Arctic Cat vehicle front differential and rear drive. RECOMMENDED TRANSAXLE LUBRICANT The recommended transaxle lubricant is Arctic Cat Syn- thetic Transaxle Fluid. This lubricant meets all of the lubrication requirements of this vehicle. FILLING GAS TANK Since gasoline expands as its temperature rises, the gas tank must be filled to its specified capacity only. Expan- sion room must be maintained in the tank particularly if the tank is filled with cold gasoline and then moved to a warm area. ft-lb N-m ft-lb N-m ft-lb N-m ft-lb N-m 1 1.4 26 35.4 51 69.4 76 103.4 2 2.7 27 36.7 52 70.7 77 104.7 3 4.1 28 38.1 53 72.1 78 106.1 4 5.4 29 39.4 54 73.4 79 107.4 5 6.8 30 40.8 55 74.8 80 108.8 6 8.2 31 42.2 56 76.2 81 110.2 7 9.5 32 43.5 57 77.5 82 111.5 8 10.9 33 44.9 58 78.9 83 112.9 9 12.2 34 46.2 59 80.2 84 114.2 10 13.6 35 47.6 60 81.6 85 115.6 11 15 36 49 61 83 86 117 12 16.3 37 50.3 62 84.3 87 118.3 13 17.7 38 51.7 63 85.7 88 119.7 14 19 39 53 64 87 89 121 15 20.4 40 54.4 65 88.4 90 122.4 16 21.8 41 55.8 66 89.8 91 123.8 17 23.1 42 57.1 67 91.1 92 125.1 18 24.5 43 58.5 68 92.5 93 126.5 19 25.8 44 59.8 69 93.8 94 127.8 20 27.2 45 61.2 70 95.2 95 129.2 21 28.6 46 62.6 71 96.6 96 130.6 22 29.9 47 63.9 72 97.9 97 131.9 23 31.3 48 65.3 73 99.3 98 133.3 24 32.6 49 66.6 74 100.6 99 134.6 25 34 50 68 75 102 100 136 CAUTION Do not use white gas. Only Arctic Cat approved gasoline additives should be used. CAUTION Any lubricant used in place of the recommended lubricant could cause serious front differential damage. CAUTION Any lubricant used in place of the recommended lubricant could cause serious transaxle damage. ! WARNING Always fill the gas tank in a well-ventilated area. Never add fuel to the gas tank near any open flames or with the engine running. DO NOT SMOKE while filling the gas tank. ! WARNING Do not overflow gasoline when filling the gas tank. A fire hazard could materialize. Always allow the engine to cool before filling the gas tank.
