I haven't had any issues with the bronze gear in the past but Crane claims their special coated gear is a "lifetime" gear. Any experience, good or bad, that you can share?

Also, any advantage to getting the gear already pinned to the shaft vs. swapping gears?

Thank you

The one in my BB is bronze and also coated. There is a small hole drilled in the oil passage close to the gear that spares oil on the gear. motor has 5000 miles on it and the gear looks like new.

What brand is it?

I have used pinnned and unpin BB oil pump drives, never a problem with either as long as something solid doesn't get sucked up into the oil pump. I have reused stock oil pump shafts for the bronze aluminum roller cam gears years ago when that was the only option with no pins or problems either later If Crane says lifetime warrenty I would probally buy one of those if I needed one I ran a Mopar brand bronze oil pump drive on my old pump gas Duster for around 3000 street miles and a bunch of 1/8 and some 1/4 mile passes shifting at or above 7000 RPM on it with no measureable wear or problems
