Bad squeaky sound, probably bent crank (3.0L)

I didn't change the gears at all. I'll gladly buy those gears from you!

Give me a few minutes and I’ll find the pump and take a photo.

Took longer to find than I had hoped. Here is the measurement (1 7/16). As you can see, both gears are the same length on this pump. The original D pump has a shorter gear on the pump body. This is your problem. The gears I have in the photo have surface rust but otherwise good. I have another pump somewhere but I won’t be able to find it until this weekend.

Here's a shot of my 2.8L pump's gear. It seems to not be much shorter -- 1 3/16". I'm sort of surprised that such a small difference would matter, since it's only 15% shorter and you'd think there'd be enough contact area along the rest of the gear, but obviously more would be better. I have no problem putting in the right gear.

I followed up in another thread, but the short version is that replacing the main bearings and using the proper oil pump seems to have fixed the problem, and I'm back to trying to get this thing tuned again. Thanks everyone!
