The rings fit well & gapped good. The instructions included with the rings didn't give enough information but the online instructions on Speedway's website was very accurate. They should be included with the rings!

This ring set had directions on how to install them in the piston but not where to install each ring in there respective grooves, also the bottom oil ring fit too tight in the cyl. and had to be hand fitted.

What are the ring thicknesses please?

View Answer

The Offenhauser shipping carton and Speedway instructions DO NOT identify the top compression ring and second compression ring. There are pictures of the various compression rings in the first figure of the Speedway INSTRUCTIONS for the 560-42620 ring set, but they are generic pictures. The ring set includes one similar to the ring at top center of the picture, but I do not see a coating on the ring, and the second compression ring is similar to the one on the bottom right of the picture of Compression Rings. So, my question is: Does Speedway or Offenhauser have a video or more documentation for this set of piston rings? My guess is that the ring similar to the one at the top center is the top compression ring , and the bottom right is the second, and that the orientation of the one at the bottom right (beveled) is oriented with the top up. Please confirm that this is correct, or send a link or detailed instructions which could be attached to your reply. Thanks
