Introduction
Credit for long service and dependable operation of a gear
drive is often given to the engineers who designed it, or the
craftsmen who constructed it, or the sales engineer who
recommended the type and size. Ultimate credit belongs to the
mechanic on the job who worked to make the foundation rigid
and level, who accurately aligned the shafts and carefully
installed the accessories, and who made sure that the drive
received regular lubrication. The details of this important job
are the subject of this manual.
NAMEPLATE - Operate Falk gear drives only at power, speed and
ratio shown on the nameplate. Before changing any one of these,
submit complete nameplate data and new application conditions to
the Factory for correct oil level, parts, and application approval.
DISASSEMBLY AND ASSEMBLY - Disassembly & assembly
instructions and parts guides are available from the Factory or
Sale Representatives. When requesting information, please give
complete data from the nameplate on the gear drive; Model,
M.O. Number, Date, RPM, and Ratio.
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.

Installation Instructions

The following instructions apply to standard Falk Type DH & DB
drives. If a drive is furnished with special features, refer to the
supplementary instructions shipped with the drive.
WELDING - Do not weld on the gear drive or accessories
without prior approval from the Factory. Welding on the drive
may cause distortion of the housing or damage to the bearings
and gear teeth. Welding without prior approval could void the
warranty.
NOTE: Drives equipped with cooling fans may require removal
of shroud when installing foundation fasteners.
EFFECTS OF SOLAR ENERGY - If the gear drive operates in
the sun at ambient temperatures over 38°C (100°F), then special
measures should be taken to protect the drive from solar energy.
This protection can consist of a canopy over the drive or reflective
paint on the drive. If neither is possible, a heat exchanger or other
cooling device may be required to prevent the sump temperature
from exceeding the allowable maximum.
MOUNTING POSITION - Standard mounting positions for
types DH & DB are with the input and output shafts horizontal.
Allowable mounting angles for standard oil levels are;
DH & DB
Consult the Factory for other angles.
If a gear drive is ordered for non-standard mounting positions,
refer to the instructions provided with the drive for oil levels and
bearing lubrication. If it is necessary to mount the gear drive in
a different position from which it was ordered, refer to the
Factory for required changes to provide proper lubrication.
FOUNDATION, GENERAL - To facilitate oil drainage,
elevate the gear drive
foundation above the
surrounding floor level. If
desired, replace the drive oil
drain plug with a valve, but
provide a guard to protect the
valve from accidental opening
or breakage.
When an outboard bearing is used, mount drive and outboard
bearing on a continuous foundation or bedplate, and dowel
both in place.
