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. On vertical shaft drives, remove fill
plug before filling or checking oil level. 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 by pumping fresh
bearing grease through the seal cage until it flows out along
the shaft. Wipe off the purged grease.
Oil Changes
PETROLEUM LUBRICANTS —
For normal operating
conditions, change oil every six months or 2500 hours,
whichever occurs first. If the drive is operated in an area where
temperatures vary with the season, change the oil viscosity 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 based on operating
temperatures and lubricant contamination. Laboratory analysis
is recommended for optimum lubricant life and drive
performance. Change lube with ambient temperature change,
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 Falk.
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 (0,030 liters) 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.

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 (0,030 liters) of “Motorstor”
H
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 Falk
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
(Steps 5 thru 8). All other repairs require removal of the drive
from the driven equipment (Steps 1 thru 4).
Removal
See note above if only seal replacement is to be attempted.
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) when:
Ratio J05 where rotation arrow indicates Clockwise H.S.
shaft rotation.
Ratio J09, J14, & J25, where rotation arrow indicates
Counter-Clockwise H.S. shaft rotation.
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 6. Take up the slack in the sling before
proceeding.
