Did my first oil change this morning, sounded pretty easy, but theres more to it than you may think. After priming the oil system, i was looking for the sump drain, i cant seem to locate it and polaris was so nice not to include it in the owners manual...lol Where is it????? 08 sportsman 500 ho

 

Use 14mm wrench,located at worst possible place,look at propshaft u-joint (from trans to front gearcase) RIGHT behind u-joint on side of engine case,tight fit,DONT strip,use 14 mm wrench only NOT 9/16" engine bolts metric, other parts standard! Dont loose washer,should be about 8 ozs oil,reinstall plug,pour in 1 3/4 quarts oil,clamp vent tube(NOT always necessary),run for about 3 minutes,remove pliers,check oil level,fill to full mark.IF aready added oil and run,JUST WAIT untill next oil change to drain everthing as sump oil is already mixed with new oil! OR if it worries you, can waste oil and filter purchased and DO again! BUT I wouldnt! Should be fine! Have customers that NEVER drain sump,But not advisable for long range life. Good luck

 

I just start the ATV and let it run for a short 20 seconds and a extra cup of old oil will pump out the oil tank drain hole from the crankcase.
