Oil pump drive gear stuck

67dodgedartconv said

I rotated the drive gear so wouldn't that be like rotating engine? Bushing looks new. So I need to pull the intake, tap the drive gear out, then probably ream the bushing? Sounds like at best brass particles get in my oil. Is there a tool for reaming the bushing?

The bushing has to be reamed/burnished AFTER being installed.
But hang-on
If you can rotate the drive gear, then it is not stuck in the bushing, and that's sortof a good sign. And yes if you can rotate it, that is the same as rotating the engine.... at this point because neither the worm gear nor the Hex is yet engaged.
Normally the worm engages the cam first, then right afterwards, the pump.
You probably already know this, but I think it's worth mentioning; The slot in the top wants to be synchronized to the driverside front intake bolt with the engine at TDC compression of #1 cylinder. Because of the worm drive, that intermediate shaft rotates into place, while almost simultaneously engaging the oil pump;and for a newbe it usually takes several attempts to get this all done. The point is that this is really difficult if the I-shaft bearing won't easily enter the bushing, and even worse if it won't come out.
Find out what the problem is and fix it. If you can spin the I-shaft, then the issue is probably that the I-shaft bearing is not entering the bushing; probably..
