INTRODUCTION
This manual applies to Sizes 1020T thru 1140T and 20T thru
140T10 Falk SteelfIex Tapered Grid Couplings. Unless
otherwise stated, information for Sizes 1020T thru 1140T
applies to Sizes 20T thru 140T respectively, e.g. 1020T = 20T,
1100T = 100T, etc. These couplings are designed to operate
in either the horizontal or vertical position without modification.
Beginning in 1994, these couplings are being supplied with
one set of inch series fasteners and one set of metric fasteners.
Use either set of fasteners, depending on your preference.
Refer to Page 6 for part interchangeability.
The performance and life of the couplings depend largely upon
how you install and service them. Carefully follow the
instructions in this manual for optimum performance and
trouble free service.
CAUTION: Consult applicable local and national safety codes
for proper guarding of rotating members. Observe all safety
rules when installing or servicing couplings.
WARNING: Lockout starting switch of prime mover and remove
all external loads from drive before installing or servicing couplings.
LUBE FITTINGS

NPT Iube holes. Use a standard grease
gun and Iube fitting as instructed on Page 4.
LIMITED END FLOAT
When electric motors, generators, engines, compressors and
other machines are fitted with sleeve or straight roller bearings,
limited axial end float kits are recommended for protecting the
bearings. Falk Steelflex couplings are easily modified to limit
end float; refer to Manual 428-820 for instructions.

LUBRICATION
Adequate lubrication is essential for satisfactory operation. Page
2 provides a list of typical lubricants and specifications for
general purpose and long term greases. Because of its superior
lubricating characteristics and low centrifuge properties, Falk
Long Term Grease (LTG) is highly recommended. Sizes 1020T
to 1090T10 are furnished with a pre-measured amount of
grease for each coupling. The grease can be ordered for larger
size couplings.
The use of general purpose grease requires re-lubrication of the
coupling at least annually.
Long Term Grease (LTG)
The high centrifugal forces encountered in couplings separate
the base oil and thickener of general purpose greases. Heavy
thickener, which has no lubrication qualities, accumulates
in the grid-groove area of Steelflex couplings resulting in
premature hub or grid failure unless periodic lubrication cycles
are maintained.
Falk Long Term Grease (LTG) was developed specifically for
couplings. It resists separation of the oil and thickener and is an
extreme pressure grease.
Steelflex couplings initially lubricated with LTG will not require
re-lubrication until the connected equipment is stopped for
servicing. If a coupling leaks grease, is exposed to extreme
temperatures, excessive moisture, or experiences frequent
reversals, more frequent lubrication may be required.
Although LTG grease is compatible with most other coupling
greases, the mixing of greases may dilute the benefits of LTG.
USDA Approval
LTG has the United States Department of Agriculture Food
Safety & Inspection Service approval for applications where
there is no possibility of contact with edible products. (H-2
ratings).
CAUTION: Do not use LTG in bearings.

DDFP engines are offered with a standard FALK drive hub,
(engine half only). See Page 41 for FALK coupling installa-
tion instructions.
If your engine includes this type coupling,please refer to the
following for service and maintenance information.
Other pump drive options available are vertical turbine drive
shaft adaptor or a standard engine flywheel. Neither of these
require regular maintenance, they are however, very critical
components and should recei ve weekly inspections during
the regular maintenance run.
