3.3 COUPLING STORAGE AND CONSERVATION
STORAGE IN THE SUPPLY DELIVERY PACKAGE
When delivered, the hydromechanical coupling steel surfaces are protected by
suitable lubricant, wrapped in a solid polyethylene bag.
Externally the packaging for couplings up to 40 kg is made of carton; the carton
box is delivered on pallet if the coupling is heavier or in crates, if it is shipped by
sea or if the client expressly requests it.
Inside the external packaging a bag contains the coupling protected with suitable
shock-proof material.
The packaged coupling may be stored for 6 months in dry, clean and protected
marine environment and for 12 months in dry, clean and protected land
environment.
3.3.1 MEASURES FOR THE FUTURE STORAGE OF THE COUPLING
NOTE
The couplings with delay chamber must be positioned inside the packaging
with delay chamber pointing upwards; the coupling filling oil will thus guarantee
sealing lubrication.
3.3.1a
The coupling must be filled with transmission oil before storage; if not, the shaft
sealing must be protected with suitable grease (AGIP 33FD, SHELL Alvania R3
or equivalent).
3.3.1b
Clean the external surfaces of the coupling and protect them with suitable
protection lubricant (type CRC 3.36 or equivalent).
CAUTION
The hydromechanic coupling and any flexible coupling with rubber
elements must be stored inside a suitable packaging, to protect it from
sunlight and dust, solvents and corrosive agents.
3.3.1c
Put the coupling in a suitable package inside an appropriate protective bag and
close it tightly.
NOTE
The packaging including a polyethylene bag can last 6 months in protected,
dry marine environment and 12 months in dry and protected land environment.
Long-lasting storage may be achieved by using a package consisting of a
hot-sealed, composite bag (aluminium and plastic) lasting 12 months in dry
and protected marine environment and 24 months in dry and protected land
environment.
3.3.1c
On expiry of the storage time, it is necessary to inspect and replace the package.
