Thanks for your responses. I removed the cannon pinion and used a smooth broach and a pair of finger nail clippers to tighten as suggested. In addition I lubricated the cannon pinion prior to staking it back onto the driving wheel. Yes, this movement has a Achilles heel with this design, but now its runs great and the hands work beautifully. BTW, good luck finding a 4F part for this caliber movement.
Again, thanks for all the help.
