Hi guys,
I saw on eBay that Midwest Super Cub made an aluminum drive hub for Vanguard engines, just like the one made for Kohler engines. So, I removed the drive assembly from my Vanguard in order to see what the flywheel looks like. Here are the pictures:
Picture #1: The 2000/3000 series drive assembly.
Picture #2: a metal colar that clamps the plastic cooling fan to the flywheel.
Picture #3: The flywheel with the drive assembly and colar removed.
It seems that the flywheel has 4 evenly spaced threaded holes that a hub assembly could bolt to, but two of the holes are used to retain the cooling fan, and the cooling fan is carved out around the other two holes, where the drive assembly mounts. Any ideas how I could bolt a drive hub to the flywheel, keeping it balanced, and still retaining the cooling fan? I thought about boring out the two holes in the fan blade and using 4 shims between the hub and flywheel to keep enough pressure on the fan so that it stays in place. Just a thought... Any other ideas?
