Bought the recommended NAPA oil filter #1365. The darn thing does'nt snug up to the o-ring seat. The threads on the filter mount run out of space and the oil filter runs out of threads before the o-ring touchs the smooth portion of the filter housing. To be sure I started it briefly and the oil came pouring out from around the o-ring. Whats up with that? I have read in this forum that people use this filter on there 500HO. Please help me out. Maybe NAPA gave me the wrong filter,I even brought in the used Polaris filter to match it up..

 

http://forums.atvconnection.com/thre...Page=DoOnePage This is the thread you are looking for. Napa 1356, 1358 Wix 51358

 

Was unable to look up that thread but found other forums on the filter # I am looking for. 1358, thanks for the effort though.

 

yep, that is the one you need, I use this on my prarie & Royal Star street bike (yamaha) if you look close, the 1358 has an indentention that allows the nut aroung the stem of the oil supply to seal, the other listed filters will fit as far as thread, but don't have enough recess to seal, the 1358 is made by wix, I run them for 6000 miles in my street bike. it fits a lot of honda's, yamahas, & quads, even will fit a mazda miata.

 

Here is a list of oil filters that should work on the HO, or any Polaris, Yamaha Kodiak and Grizzly.

WIX 51358
AC 2057
NAPA 1358
PUROLATOR ML 16819
FRAM 6017A

 

Will these filters also work on the regular sportsman 500?

 

yes

 

I think that the oil filters listed will fit all Polaris 4 strokes with the exception of the 700. I have read that the 1356 fits the 700. I do not understand why Polaris would change the oil filter on that engine.
