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.
PACKING GLAND SEAL —
Section I, Step 4(C)
Oil Changes
PETROLEUM LUBRICANTS —
For normal operating
conditions, change gear oil 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. Where applicable,
grease seals when changing oil. Refer to Appendix A.
SYNTHETIC LUBRICANTS —
Synthetic lube change intervals
can be extended to 8000-10,000 hours depending on
operating temperatures and lubricant contamination.
Laboratory analysis is recommended for optimum lubricant life
and drive performance. Change lube with changes in ambient
temperature, if required. Refer to Appendix A.
Stored & Inactive Drives
NEW DRIVES WHICH HAVE NOT BEEN OPERATED —
Each
drive is spin tested with a rust preventive oil that will protect
internal 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 drive is to be stored or inactive beyond the above periods,
spray all internal parts with a rust preventive oil that is soluble in
lubricating oil or add 1 ounce (23,35 grams) of “Motorstor
H
”
vapor phase rust inhibitor oil. Seal air vent immediately with
pressure sensitive tape.
Before operating drives which have been stored or inactive,
remove tape and fill to the proper level with oil meeting
specifications given in the Lubrication Recommendation found
in Appendix A.

known as “Nucel Oil.”)
SHUTDOWN OF NEW OR EXISTING DRIVES WHICH
HAVE BEEN OPERATED —
If a drive is to be stored or inactive
for more than 2 months after a period of operation, add 1
ounce (23,35 grams) of “Motorstor” to the oil sump and
immediately seal the air vent with pressure sensitive tape. It is
not necessary to drain the oil prior to storage if oil is still
serviceable and not contaminated.
Before operating drive, remove tape and check oil level.
PERIODICALLY INSPECT STORED OR INACTIVE DRIVES AND
SPRAY OR ADD RUST INHIBITOR EVERY SIX MONTHS, OR
MORE OFTEN IF NECESSARY. INDOOR DRY STORAGE IS
RECOMMENDED.
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 stated above, if specified on
the order.
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.
