It'* cool now. I had some time to clean it up and look and think about it.
The crank is not damaged bad enough to warrant replacement. The keyway is good. The keyway in the trashed balancer is only half there. It'* really bad but I have a replacement for that. Now I know the consequence of not having a balanced balancer.
Took off the timing chain and gears. They really need replacement too. Chain was very loose. Both sides would touch.
It could have easily jumped a tooth but hadn't so far.
Heads won't be finished until next week and the new cam hasn't come in yet.
Doesn't matter too much cause I'm away on business for the next few days.
The new oil pump has the pick-up screen brazed on for security now.
So what I decided to do to fix the loose fit it to peen the shaft fit with a center punch to knurl a tighter fit, then use some Loctite 620 hi temp retaining compound. Should work fine. The bolt that holds it on is the tightest on the whole car at 220 ft-lbs.
I'll post some more pics next week.
I'm going to pop off a cap or two to check the bearing clearances. Might as well now that I'm this far into it.
