Note: The issue with power 
train damage is that it is cu-
mulative. Typically it does not 
cause immediate catastrophic 
system failure, but rather a  
one-time out-of-spec usage 
could damage hardened gear 
coating such that regular in-
specs operation is now causing 
small cumulative damage every 
time you use it.
