1. When spinning the Duke Oil Pump with a drill, do you go clock wise, or 'backwards'. I know most cars are clockwise, but on the Duke the Cam spins the other way since it is Gear driven rather than Chain driven. Does this mean the pump spins backwards too?

2. How fast should I spin the drill? Just few revs per minute, or should I be going at like 50% of the dill capacity?

Bump - no one prime a duke pump?

Perhaps it does not matter. I can't see that you will damage anything if you are going the wrong way.....but I am guessing because nobody is responding to your question, and I decided to bump it.

Thanks Gall, I am not really worried about damage, but want to make sure oil is flowing correctly to every where it should. That's why I'm also wondering about how fast to run the drill when priming.

Don't worry too much about the speed. You just need maybe two hundred RPM. You'll be able to tell if you're going the right way because the drill will load up.
Unfortunately the only picture I ever took of priming a duke is pretty blurry.
