Re: FE290 engine rebuild
Going back together
First I always like to run a hone through the cylinder. You're not trying to bore it out so it only takes a few seconds, but you want to clear the glaze off the cylinder walls for a couple reasons. 1. To make sure theres no vertical scoring you didnt notice before. And 2. To help the new rings seat.
Then take both the top and 2nd ring and set them into the cylinder. Use the piston to push them evenly (separate from one another) and then measure the ring end gap with a feeler gauge. I've got .015" here on both
The ring going on the top of the piston is the one with the chrome edge. The 2nd ring isnt chrome. The 2nd ring has an R on the top side next to the end of it. Refer to the service manual for ring orientation
