Lubricant Changes

OIL ANALYSIS REPORT

—

Checking oil condition at regular

intervals is recommended. Analyze oil samples approximately
every 1000 hours for petroleum EP lubricants or every 3000
hours for synthetic EP lubricants. In the absence of more
specific limits, the guidelines listed below may be used to
indicate when to change oil:
1. Water content is greater than 500 ppm (parts per million)

(0.05%).

2. Iron content exceeds 150 ppm.
3. Silicon (dust/dirt) exceeds 25 ppm, above reference sample

from new oil container.

4. Copper content exceeds 75 ppm.
5. TAN (Total Acid Number) 50% increase above reference

sample from new oil container.

6. Viscosity changes more than ±15%.
Laboratory analysis is recommended for optimum lubricant life
and gear drive performance.

PETROLEUM EP LUBRICANTS

— For normal operating

conditions, change EP lubricant every 6 months or 2500
operating hours, whichever occurs first. Change oil more
frequently when gear drives operate in extremely humid,
chemical or dust laden atmospheres. In these cases, EP
lubricants shall be analyzed to determine proper change interval.
Refer to Table 2 for EP lubricant viscosity recommendations

SYNTHETIC EP LUBRICANTS

— Synthetic EP lubricant

change intervals can be extended to 8000 hours depending
upon operating temperatures and lubricant contamination.
Change oil more frequently when gear drives operate in
extremely humid, chemical or dust laden atmospheres. In these
cases, synthetic EP lubricants shall be analyzed to determine
proper change interval. Refer to Table 3 for synthetic EP
lubricant viscosity recommendations.

Grease Lubricated Seals

—

Depending on the frequency and

degree of contamination (at least every six months or when
changing oil in the drive), purge grease from seals by first
cleaning grease fitting and then slowly pump fresh grease,
WITH A HAND GREASE GUN, through the seal cavity until
fresh grease flows out along the shaft. Wipe off purged grease.
Refer to Table 10 for NLGI Grade #2 greases. Some greases
are of the EP type and may contain toxic substances not
allowed in the food processing industry. Grease that meets the
USDA or NSF “H-1” classification is suitable for food
processing applications. Consult Factory.

CAUTION:

Rapid greasing with a power grease gun can force

grease inward past the seals causing seal leaks.

GREASE LUBRICATED BEARINGS (Torque Arm)

— Most

shaft mounted drives have a grease lubricated bearings in the
torque arm. Grease bearings during oil changes or at intervals
of every 6 months or 2500 hours of operation whichever is
less.

Stored & Inactive Gear Drives

Each gear drive is protected with a rust preventative that will
protect parts against rust for a period of 4 months in an
outdoor shelter or 12 months in a dry building after shipment
from the Factory.
If a gear drive is to be stored, or is inactive after installation
beyond the above periods, drain oil from housing and spray all
internal parts with a rust preventative oil that is soluble in
lubricating oil or add “Motorstor”™ vapor phase rust inhibitor
at the rate of 1.05 liters per cubic meter (one ounce per cubic
foot) of internal drive space (5% of sump capacity). Refer to
Table 8 for Motorstor quantities. Rotate the shafts several times
by hand. Before operating, drives which have been stored or
inactive must be filled to the proper level with oil meeting the
specifications given in this manual. Refer to Manual 128-014
for “Start-up after Storage” instructions.
Periodically inspect stored or inactive gear drives and spray or

add rust inhibitor every six months, or more often if necessary.
Indoor dry storage is recommended.
Gear drives ordered for extended storage can be treated at the
Factory with a special preservative and sealed to rust-proof
parts for periods longer than those cited previously.
The vented dipstick should be replaced with a plug (vented
dipstick should be attached to gear drive for future use) so that
the protective rust inhibiting atmosphere is sealed inside the
drive. Install vented dipstick when preparing drive for operation.
