Worm Gearbox line
4.1 Preparation for Storage:
a) Remove all moisture from the gearbox;
b) Check the oil level and complete if necessary with the lubricant recommended in the product
manuals;
c) On gearboxes supplied with lubricating oil, add VCI (Volatile Corrosion Inhibitor) anticorrosive agent
to the lubricant to the extent of 2% of the lubricating capacity.
d) In the case of gear geraboxes supplied without oil, mix 10% of the total volume of the lubricant
recommended in the manuals with 2% of this total volume of VCI and fill the reducer. VCI additive
reference MV OIL 1061 (http:// www.vcibrasil.com.br).
Mineral oil already with VCI (Castrol Alpha SP 150 S or Castrol Alpha SP 220 S);
e) Seal the gerabox completely by hermetically closing the air holes (vents) and the area around the
level dipstick with an adhesive tape (if level dipstick is present);
f) Place grease around the shafts near the retainers and then wrap the shaft areas near the retainers
with an adhesive tape leaving the shaft flush with the retainers;
g) For external fastening surfaces (shafts and flange faces) they are Factory protected; inspect and
protect these surfaces if necessary (in case of film loss) with appropriate corrosion protection (Castrol
Safecoat DW 801 Corrosion Protection Oil or similar layer of approximately 50
μ m). Any damage
caused by transport must be corrected.
h) If the gearbox is stored outdoors, place it on blocks. Make a frame around it (if possible) and cover it
with tarpaulin (cotton wax is recommended). Leave the bottom open to receive ventilation.
4.2 Operation after Storage:
If the storage or stop time exceeds 2 years or the ambient temperature deviates from the normal range
during storage, the gear unit lubricant must be replaced before commissioning.
Since they have been properly lubricated, the retainers must be replaced after 2 (two) years.
a) Remove any tape used in preparation for storage;
b) Remove any moisture that may have accumulated in the gearbox, clean the gearbox and inspect for
damage;
c) The VCI corrosion protection agent is soluble in recommended lubricating oils and does not need to
be removed from the gearbox;
d) Check this manual for recommended lubricants and installation, maintenance and operating
instructions;
e) In case the gear reducer is filled with oil, the amount of oil must be reduced to the recommended
amount before commissioning. See chapter "Mounting positions and lubricant quantities".
If required, gearbox prepared for "long-term storage" can be supplied. In this case, WEG-CESTARI must be
informed during the quotation and purchase process.
For storage periods longer than 9 months, the gearboxes/geared motors may only be put into operation if
the above procedures have been followed.
