    99 Polaris Genesis help with WSM "beveled" piston rings

    hi,i have had this 99 polaris genesis sitting for 2 years. i got good used cases,new oem crank, and just bought a set of wsm pistons,rings,etc, I am about to put everything back together and me and my neighbor noticed that on the piston rings one side of the rings is beveled. There were no instructions about this except that if there is a polished edge it goes on the top which there is nothing polished, one person told me to put the beveled edge on each ring facing upwards. What do you people think.I need more than the one opinion i got going this far. Thanks for suggestions/comments.

    Welcome to the Hulk Mark!
    The bevel goes up. The compression pushes against the bevel to help push the rings tight against the cylinder wall. If you put them upside down, the rings will stick in the ring groove, and not move freely when compressed.

    Hi. thank you. and thanks for the reply. Now i just need to find out all the torque specs for the bolts, I need to get these crankcases together for i can start this project. Hopefully there is a free manual download on here.

    Welcome to Green Hulk
    The domestic engines I've seen use a "L" shaped upper ring. The piston top will also have room for the L shape. It deffinetly points up. I think the Polaris lower ring was a square cut.

    And yes there are Polaris service manuals in the Tech section,full manual downloads.

    Unfortunately my computer has too old of software(5 years old!!??) to view the manuals after i download it so im just sitting here staring at the crankcases and case bond because i need torque specs on the cases before i start. Does anyone have them or can they possibly look and see. I basically need the case torque specs and the cylinder torque specs just to get started. Much appreciated.

    Actually i had someone else download the 318 page manual as well and saved it 2 different ways and they had no luck just like me. Nothing shows up. It is blank. There is something wrong with that link to the 99 Polaris service manual. Anybody know another place to downlaod it. Is there anybody with a manual they can check or remembers the torque specs for the cases and cylinders?

    1999 Genesis manual PDF download should be working
    It is a very large file, almost 200MB.

    Check the hints at the top of the download page. You must be using a current version of Adobe READER, which is free to download and install. Also download and install the Firefox browser. They should both work, even on a five year old computer.
