Filing Ring End Gap

Duration: 1:54

Here’s a tech tip for your Harley top-end rebuild. Before you can install your pistons you will need to check the ring end gap. Push the ring in cylinder, use the piston to push it down in a little bit and measure your gap. Your manufacturer’s spec is check with a feeler gauge.

If it is tight you will need to open up the ring end gap. No need for a fancy (expensive) tool. Put a file in the vise and on one side of the ring file it down nice and flat. Check as you go.

    Good practice to dress off the burrs from where you have filed the rings, these could scratch the bore.
