Buckley's lasted over 10,000 miles...BUT, he ran a dry sump with an outside
oil pump.
If I was still running a solid roller, I think I would check it at 1,000 miles or so just to see how much wear is going on, and then gauge it from there.
The only way a bronze gear can hurt something else is if it just plain breaks and you have pieces running through the system. Usually, they just wear down to where they no longer grip. When the teeth start getting sharp...time to change it.
The only other extra things I carry are generally electrical, given the original-style wiring on mine...a couple of Lucas horn relays for the lights and fans, inline fuses/good length of wire, and, on long trips...an extra electric fuel pump (I don't run a mechanical).
The specter of a rabid naked ERA-obsessed river-dancing soul can be strong motivation for being reasonably prepared.
Note...two out of two lawyers use flat tappet cams and have told you the same thing about bronze gears. Will you believe us if we bill you?
