Hi Colyn –
Yes, there is more vibration. However, I found this in the
Hartzell Propeller owner’s manual
(3) Hartzell Propeller Inc. recommends that new or newly
overhauled propellers be lubricated after the first one or two hours of
operation because centrifugal loads will pack and redistribute grease, which
may result in a propeller imbalance. Redistribution of grease may also result
in voids in the blade bearing area where moisture can collect.
I still need to regrease the hub and dynamically balance the
engine/prop combination. I’m off to Florida
tomorrow for vacation so it will have to wait until I return. I’ll keep you
posted.
Happy Holidays,
Adam Molny

Adam,
glad
you got your plane back. This would be great stuff to have in a buyer's
kit.
Curious
if you notice any vibration difference between the Hartzell metal prop and the
old one.
