I took a junk sleeve to do a show and tell on tractor talk a few days back. The ring in the picture is way way to wide. It is .029" It should be .007 to be up to specs.
How to measure the ring gap with a feeled gauge.
What a ridge reamer looks like. I never remove a piston with out first using a ridge reamer. I want to see the ridge cutter witness on the top of the cylinder wall even if I can not feel a ledge. You can see in the above picture where I used the ridge reamer on the junk sleeve before removing it by the rust.
This is a picture of a B but the offset is the same principal. You can also see that when the rod is proper that the rod is centered on the wrist pin in the piston.
