LONG TERM STORAGE

During periods of long term storage (6 months or
longer) special procedures must be followed to
protect the reducer and insure that it will be in good
condition when put into service.
1. Replace lubricant in the reducer with Mobil
SHC634 blended with 2% by volume of Daubert
Chemical Nox-Rust VCI-105. Fill gearcase 90%
full. Rotate the input shaft at least 60 revolutions to
distribute the lubricant.
2. Apply a thick coating of chassis-type grease,
Cosmoline, Daubert Nox-Rust X-110 or equivalent
coating to all unpainted
threads, bores, shafts and keyways.
3. If unit is equipped with a motor, measure stator
insulation resistance with a megohmeter and
record reading.

4. If unit is to be stored out of doors or in a damp or
unheated indoor area, cover the entire exterior with rust
preventive, then seal the unit in a moisture proof
container or polyethylene bag with desiccant. Protect
the enclosure from direct sunlight.
5. Rotate the input shaft at least 60 turns monthly to
redistribute the lubricant.
Return to service from long term storage:
1. Remove all protective coatings. If unit has been
stored more than 3 years or in high temperatures,
replace all oil seals. Check hardware for proper
tightness.
2. Drain and refill the reducer with the proper amount
and type of lubricant.
3. If unit was equipped with a motor, check motor stator
insulation resistance with a megohmeter. Compare to
original reading. Resistance or less than 1 megohm or
50% of the original resistance requires the motor to be
removed and dried. If drying does not restore the
winding insulation resistance, the motor must be
repaired or rewound.
4. Motor drying: Refer to a motor repair shop.
5. When stored motors are found to be wet, motor
should be disassembled and inspected. Remove
endshields, inspect bearings and grease for moisture
and rust. Replace/rebuild as necessary.
