The reason for getting this right is that the assembly forms a compound bar to withstand the sideways thrust of the Centa rollers - something the original crankshaft was not designed for.

I know I'm splitting hairs here, but in the original use of the Wedge S&S motor, the entire crank end load WAS side load. Twist the throttle and the primary chain tightens and pulls the crank sideways back towards the clutch basket. I'm guessing that S&S engineered the side load of the Wedge crank, but then again, that end of the crank that is involved with the Centa is a direct copy of the Harley crank. The only difference is that the S&S motor uses a one-piece crankshaft with side by side staggered rods, unlike the Harley split rods on the same crankpin and centerline.
Older British cars used spacers on their wheel bearings and shimmed the pre-load on the wheel bearings. This did the same thing in that it added lots of strength to the axle as the spacer literally increased the axle diameter when stressed to the correct torque.
I can't help but think that Phil's mods to the inner and outer Centa housings have made a huge improvement on the stability and durability of the of the crank in general. Having the inner and outer piloted via the inner end shaft into the outer housing bushing adds lots of guidance and support to the total assembly.
Hope you all get this figured out soon...:)
Hope you are all having a great new year!
