    Hi, I have an offset mag drive in my Hemi. When I crank the engine over by hand I can see the shaft going up an down as it clicks over on the lobes of the mag. The collar on the shaft has a 90 thou gap between the actual offset mag body when I pull the shaft down. Should this collar be tight up against the offset mag body? I hope you can provide me some advice.

    I had the same issue and I found some shims in different thickness to get the shaft end play down to something fairly tight. I cant remember what I set it at...

    Do you know what brand mag drive it is? Call RCD and ask them what the spacing should be and they probably have the shins. If it is an RCD drive then they could rebuild it for you.
