Annual maintenance of tank PTO
The PTO through the tank must be kept in good and well-greased
shape, to secure it telescopes.
If it does not, it will provoke destructive pressure against the pump and
gear box.
A non-telescoping PTO as well might provide destructive vibrations in
the spray.
Unbolt the PTO from pump and gear box.
Unbolt and take the pump out with a crane.
Take the PTO shaft out.
Pull the PTO apart in male and female parts.
Clean it well.
Grease it.
Grease Gearbox PTO tap and pump PTO tap.
Put back in the PTO shaft and bolt on the gear box tap.
Put back the pump with a crane and bolt it to the chassis.
Bolt on the PTO to the pump.
Remember weekly PTO greasing / every 50 hours of the tank PTO.

WARNING!If the transmission shaft is not cleaned and
lubricated as described it will not be able to extend or retract
during operation when load is applied. This may overload the
bearings on pump and gearbox or cause vibrations in the
transmission and fan!
