Piston ring installation

Discussion in 'The Garage' started by Sundie, Mar 24, 2010.

  1. Hey All:

    I've gotten new rings form Mike's, and i thought one of the top 2 rings was supposed to be angled on it's edge, but i can't for the life of me tell if either of them are... There are also no marks for "up/down". Is it just put them in either way?

    Also, what exactly does "tapered" mean for the 2nd oill wiper ring?

    - the size should be stamped on the top of the ring where the gap is
    - tapered is the shape of the second compression or wiper ring ... the pointed part should be towards the crank...its job is to scrape xs oil off the cylinder wall

  4. For the life of me, i can't see that taper in the wiper ring. I do see an "R" on the wiper ring, and an "RN" on the compression ring. These should be the top then?

    - yes, normally marked on the top, the taper is not necessarily going to be visible to the naked eye

    - i normally very gently take the sharp corner edge off the top compression ring with a fine stone
