BB Mopar Crank Drive Mandrels

Quote:

What is everyone using for a Vac pump or oil pump drive mandrel when using a BB Mopar balancer with a Chevy bolt pattern? Nothing clears the head of the damper bolt.....it's not even close with an ARP damper bolt. Who makes mandrel drives?

I've already checked Peterson, Moroso, Star....

I'm not home with my books but CV Products is where
I got all my drive stuff from

Just throwing this out there Brian but did you try Rons?

Brian... this is one way for the CV system... they
have a bolt on plate to the balancer and then you add
what you want... or as in my case I used the bolt on
pulley then added what I wanted then the "HAT" at
the end with the center bolt

I haven't looked at CV yet either. The big problem is with the BB balancer hub because it forces the balancer bolt to sit proud of the balancer a good distance where a SB Mopar balancer hub allows the balancer bolt head to sit below the front face of the balancer. Whatever bolts to the balancer face needs to have a large counterbore to clear the bolt head. Nothing I can find yet has this.

I used the Peterson spline drive setup and then clearanced the back side for the bolt head.

Might look here. Always had good luck with Jones Products for pullies and belts. I have also used and liked the spline drive as well it's the shiznit

I have a crank trigger so that acts as a spacer. I used a standard OEM crank bolt. I didn't have to machine much off the backside of the spline drive hub, just a small pocket.

I used to make these spline drive hubs for Mopar engines but nobody bought them so I quit making them.

SB isn't the only thing that makes it on my stand...

The CV products drive setup doesn't use a shaft w/ a keyway either. They use a "pinned" drive setup...it just stacks together and aligns w/ 2 dowel pins. Then one long bolt just holds the stack together.

Me personally, I HATE the stuff with the long bolt. I want the bolt to hold the balancer only, then the drive centers in the register and uses the 3 balancer bolts to attach. To me this is a much better design, as well as being able to turn the motor either way with the drive

The long bolt doesn't bolt to the crankshaft. You use a normal short crank to balancer bolt. Then bolt on the crank/drive hub like a normal crank pulley would bolt on. The long bolt just holds the stack of pullies/spacers to the drive hub.
