Section II
DRIVE SERVICE & REPAIR
PREVENTIVE MAINTENANCE
PERIODICALLY — Carefully check the oil level of the drive
when it is stopped and at ambient temperature; add oil if
needed. If the oil level is above the specified level, have
the oil analyzed for water content. Moisture in the oil may
indicate seal leakage or condensation. If so, correct the
defect immediately and change the oil. DO NOT overfill or
oil leakage may result. If a drive is equipped with a fan,
periodically clean accumulated foreign matter from the fan
and fan guard to allow adequate air flow.
GREASE PURGED SEALS — Periodically (at least every
six months), depending upon the frequency and degree
of contamination, purge contaminated grease from seal
by slowly pumping fresh bearing grease through the seal
cage, WITH A HAND GREASE GUN, until fresh grease
flows out along the shaft. Wipe off the purged grease.
Refer to Appendix A.

OIL CHANGES
Refer to the Lubrication Recommendations Section in
Appendix A.
STORED & INACTIVE GEAR DRIVES
Each drive is protected with a rust preventive 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, add Nox-Rust VCI-10
vapor-
phase rust inhibitor. For drives that have oil installed, add
Nox-Rust VCI-10 vaper-phase rust inhibitor at the rate of
2% of sump capacity. For drives without oil, add Nox-Rust
VCI-10 vapor-phase rust inhibitor at the rate of one ounce
per cubic foot of internal drive space. 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.
c Product of the Daubert Chemical Company, Chicago, Illinois.
Periodically inspect stored or inactive gear drives and
add Nox-Rust VCI-10 every six months, or more often if
necessary. Indoor dry storage is recommended.
The air breather should be replaced with a plug (air
breather should be attached to gear drive for future use)
so that the protective rust inhibiting atmosphere is sealed
inside the drive. Install air breather when preparing drive
for operation.
WARNING: The rust preventative oil from the factory
and Nox-Rust VCI-10 are not H1 registered with the NSF
(National Sanitation Foundation) as suitable for food
processing applications. When Food Grade Lubricants are
to be used, it is the end users responsibility to properly
flush and prepare the drive for Food Grade service.
Contact the lubricant manufacturer for specific information
and flushing procedures.
REPAIR & REPLACEMENT
WARNING: Consult applicable local and national safety
codes for proper guarding of rotating members. Lock out
power source and remove all external loads from drive
before servicing drive or accessories.
NOTE: Only the seals on the input side of the drive can
be replaced without removing the drive from the driven
equipment. All other repairs require removal of the drive
from the driven equipment. Proceed to Step 1 for drive
removal. Proceed to Step 5 for replacement of seals.
Removal (See above note for seal replacement only)
1. JR, JF & JSC — Drain the lubricant at this time.
Remove safety guards and belts (motor and motor
mount, optional). Remove backstop (if so equipped).
Refer to Section II, Step 10, for backstop removal
instructions.
WARNING: Drive must be supported during removal
process. Use a sling around the motor mount or as
recommended in Section I, Step 7. Take up the slack in the
sling before proceeding.
