500 Oil Change Question
Hi All,
I was just curious...but WHY did Polaris go with an Oil Tank on the 500's?
Seems like a lot of hassle to drain both oil tank and crank case?!? Plus that screen fitting too.
Just curious...and sorry if the question has been asked before...but the search did not find what I was after.
Thanks!

Why???
Actually...that isn't very accurate. Its two bolts...and the oil screen fitting also. Plus...purging the air from the line after changing the oil. Not saying it to be hard...just curious WHY?
Do you have any facts to offer to the discussion of WHY? I'd like to hear them...because I am curious about the setup.
As you can tell...I have never owned a SP 500...so just trying to educate myself.
Thanks,

[QUOTE=biz4two;2978977]Hi All,
I was just curious...but WHY did Polaris go with an Oil Tank on the 500's?
I can't honestly say why, and never cared but here's a couple theory's since no one here has answered . 1: an external oil tank may help minimize the engine's dimensions? 2: Perhaps having the tank external aids in keeping the oil at a cooler running temp? 3: It was designed by the Japanese, I think? 4: It was designed by the Japanese, I think? My best guess would be theory 2 since my 325 is an air cooled and yet it has a oil cooler similar to a radiator. But that makes me wonder why don't other brand name (like honda for example) air cooled engines do this? Maybe it's just a Polaris thing?

Most high end race engines have this type of oiling system.
There are advantages to using a dry sump system. One is HP. It takes a bunch of HP to spin a crank through oil. If most of the oil is in a tank and not nex to the crank your going to pick up a bunch of HP.
Another is CG. On a race car the lower you can get the weight the better handling you will get. With a dry sump, you can run a flat pan and move the engine down in the chassie and get the CG way down. I wish I could run a dry sump in the car I race but the rules say no.
Anyway, there are more advantages to a dry sump. Google is your best friend.

I doubt that the HP gains in a 38 HP ATV from a dry sump are significant, but I suppose there is something there.
I'm of the believe, and always did believe that Polaris did this for the CG. However, when they went to the plastic tank... that was too far. Ask anyone who has put a stick through one, or had a rock crack the case. Not only did Polaris save money with the plastic case, they made money by selling replacements.
