EAU20042 Transfer case oil The transfer case must be checked for oil leakage before each ride. If any leakage is found, have a Yamaha dealer check and repair the vehicle. In addition, the transfer case oil level should be checked and the oil must be changed at the intervals specified in the periodic maintenance and lubrication chart. To check the transfer case oil level 1. Place the vehicle on a level surface and hold it in an upright position. NOTE: Make sure that the vehicle is positioned straight up when checking the oil level. A slight tilt to the side can result in a false reading. 2. Remove the oil check bolt, and then check the oil level in the transfer case. NOTE: The oil should be at the brim of the check hole. 14. Install the engine oil filler cap. 15. Start the engine, and then let it idle for several minutes while checking it for oil leakage. If oil is leaking, immediately turn the engine off and check for the cause. 16. Turn the engine off, and then check the oil level and correct it if necessary. 17. Install the rider seat. 6 CAUTION: G In order to prevent clutch slippage (since the engine oil also lubricates the clutch), do not mix any chemical additives. Do not use oils with a diesel specification of "CD" or oils of a higher quality than specified. In addition, do not use oils labeled "ENERGY CONSERVING II" or higher. 6-13
