The propeller shafts are supplied by the supplier as assemblies
ready to be mounted.
They are statically and dynamically balanced.
The plates welded to the transmission shafts are balancing
plates.
If the plates are missing, it will be necessary to re-balance the
shaft.
Working on the transmission shaft and, at the same time, but
in the opposite direction, on the sliding sleeve (arrows) check
that there is no clearance between the grooves.
Working on the forks of the sleeves (arrows) check that the
spiders are not worn. If they are, replace them as described
previously.
