5 — Pack With Grease And Assemble Covers
Pack the spaces between and around the grid with as much
lubricant as possible and wipe off excess flush with top of
grid. Position seals on hubs to line up with grooves in cover.
Move lower cover half into position and block-up in place.
Sizes 1150 thru 1230 —
Position gaskets on flange split
and assemble upper cover half with the match mark on
the same side as the lower half (see above). If shafts are
not level (horizontal) or coupling is to be used vertically,
assemble cover halves with the lug and match mark UP or
on the high side.
Push gaskets in until they stop against the seals and
secure cover halves with fasteners, tighten to torque
specified in Table 1. Make sure gaskets stay in position
during tightening of fasteners.
CAUTION:
Make certain
lube plugs are installed before operating.
Sizes 1240 thru 1260 —
Check all
flange faces for burrs and coat either
half with Permatex #2 or equivalent.
Assemble cover half with the internal
pin (see drawing at right) on the same
side as the lower half. Secure cover
with fasteners and tighten to torque
specified in Table 1. Assemble split
seal retainers so the split is 90° from the cover split. Secure
with fasteners.
CAUTION:
Make certain lube plugs are installed before
operating.
ANNUAL MAINTENANCE
For extreme or unusual operating conditions, check
coupling more frequently.
1. Check alignment per steps on Page 3. If the maximum
operating misalignment limits are exceeded, realign the
coupling to the recommended installation limits. See
Table 1 for installation and operating alignment limits.
2. Check tightening torques of all fasteners.
3. Inspect seal ring and gasket to determine if
replacement is required. If leaking grease, replace.
4. When connected equipment is serviced, disassemble
the coupling and inspect for wear. Replace worn parts.
Clean grease from coupling and repack with new
grease. Install coupling using new gasket as instructed
in this manual.
Periodic Lubrication
The required frequency of lubrication is directly related to
the type of lubricant chosen, and the operating conditions.
Steelflex couplings lubricated with general purpose
coupling greases, should be relubed annually. The use of
Falk Long Term Grease (LTG) will allow relube intervals
to be extended to beyond five years. When relubing,
remove both lube plugs and insert lube fitting. Fill with
recommended lubricant until an excess appears at the
opposite hole.
CAUTION:
Make certain all plugs have
been inserted after lubricating.
Coupling Disassembly And Grid Removal
Whenever it is necessary to disconnect the coupling,
remove the cover halves and grid. A round rod or
screwdriver that will conveniently fit into the open loop
ends of the grid is required. Begin at the open end of the
grid section and insert the rod or screwdriver into the loop
ends. Use the teeth adjacent to each loop as a fulcrum
and pry the grid out radially in even, gradual stages,
proceeding alternately from side to side.
