The size of this overlap depends on the pump model:
First installation of the transmission shaft is done in the following
way:

with shortest distance between the tractor and sprayer pump P.T.O.
shafts.

Fit the two shaft parts at tractor and sprayer pump and measure
how much it is necessary to shorten the shaft. Mark the protection
guards.
