Lubrication Recommendations

COLD CLIMATE CONDITIONS —

The proper viscosity grade

of synthetic lubricant is given in Table 4. Usable temperature
ranges can sometimes be widened for synthetic lubricants if
specific application conditions are known.

CAUTION: SYNTHETIC LUBRICANTS & INTERNAL

BACKSTOPS –

Synthetic lubricants may be used in drives with

internal backstops operating in cold temperatures –30° to
+50°F (–34° to +10°C). Select proper lubricant grade from
Table 4. Mobil SHC 624 and SHC 626 provide proper
backstop action under these conditions. Other synthetic
lubricants may also be acceptable. DO NOT use synthetic
lubricants in drives with backstops operating in ambient
temperatures above 50° F (10° C).

NORMAL CLIMATE CONDITIONS —

For temperatures of

15°F (–9°C) and above, use viscosity grades as recommended
in Table 5 for petroleum based lubricants. Petroleum based and
synthetic lubricants are suitable for normal climate conditions.
Usable temperature ranges can sometimes be widened for
synthetic lubricants if specific application conditions are known.

WARNING: SYNTHETIC LUBRICANTS IN FOOD

PROCESSING INDUSTRY –

Synthetic lubricants may contain

toxic substances such as sulfur, phosphorus, chlorine, lead
derivatives, graphite or molybdenum disulfides and should not
be used in the food processing industry without the lubricant
manufacturer’s approval. Lubricants which meet USDA “H1”
classification are suitable for food processing applications.

Lubricant Changes

OIL ANALYSIS REPORT —

Checking oil condition at regular

intervals is recommended. 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 0.05% (500 ppm).

2. Iron content exceeds 150 ppm.

3. Silicon (dust/dirt) exceeds 25 ppm.

4. Viscosity changes more than 15%.

PETROLEUM LUBRICANTS

— For normal operating

conditions, change gear oils every six months or 2500
operating hours, whichever occurs first. If the drive is operated
in an area where temperatures vary with the seasons, change
the oil viscosity grade to suit the temperature, refer to Table 1.
Lubricant suppliers can test oil from the drive periodically and
recommend economical change schedules.

SYNTHETIC LUBRICANTS —

Synthetic lube change intervals

can be extended to 8000-10,000 hours depending upon
operating temperatures and lubricant contamination.
Laboratory analysis is recommended for optimum lubricant life
and drive performance. Change lube with change in ambient
temperature, if required. Refer to Table 4.

Grease Lubricated Seals

All drives are furnished with grease purged seals which
minimize the entry of contaminants and abrasive dusts into the
drive. Drives are shipped with NLGI #2 grease in the seal
housing cavities unless otherwise specified.

Whenever changing oil in the drive, purge the seals with one of
the NLGI #2 greases listed in Table 3.

Some of these greases are of the EP type and may contain toxic
substances not allowed in the food processing industry. If
grease could contaminate the product, as in the food and drug
industries, the grease should be removed. A grease that meets
the USDA “H1” classification is suitable for food processing
applications.

Periodically (at least every six months) depending upon the
frequency and degree of contamination, purge contaminated
grease from seals by slowly pumping fresh bearing grease thru
the seal,

WITH HAND GREASE GUN

, until fresh grease flows

out along the shaft. Wipe off purged grease.
