3 yrs ago I bought an old 1999 Sportsman 500 6x6 Big Boss. Recently I had a local-yocal change my oil while doing other more serious work on it-- new cam. When I later checked the oil I was amazed how HIGH the oil was on the dipstick.
That was a year ago.
I just changed the oil and followed the procedure to the letter in the manual which is an amazingly detailed process if you have not ever done so. Are ALL ATV's this complicated for an OIL change?!
-- drain the sump tank
-- drain the crankcase (after removing skid plate and busting knuckles accessing the port)
-- refill the sump with 2 qt oil
-- Oil check reveals it is WAY high now.
-- squeeze off the vent port so the pump is primed and run the engine for a few seconds. (Sucks the overfull
sump oil into the crankcase where it can prime the pump)
-- Recheck the oil level and, sure enough, it is back in the normal range, top it off.
So, what are the ramifications if this is NOT
done. Well, based on what I saw, you lose lubrication! Or did I miss something?
Attached is pump priming procedure which I have made notes on-- embellishing it for clarity.
I would really like input from technical experts here! thanks.
