I didn't know they didn't! I've been thru a lot of things, that have a seal running on aluminum, and they all, at least what I've been into, have a groove in the aluminum. I've worked with seal manufacturers in the past, and they make a sleeve, and another seal, that will replace the grooved area, if it gets to leaking. Don't think being run on dirt, has much to do with it, I've seen it on harmonic balancers, everything. Not to worry, unless it's leaking. Bob
