ANNUAL MAINTENANCE
For extreme or unusual operating conditions, check coupling
more frequently.
1. Check tightening torques of all fasteners.
2. Inspect seal ring and gasket to determine if replacement is
required; if leaking grease, replace.
3. When connected equipment is serviced, disassemble,
clean grease from coupling, inspect for wear, and replace
worn parts. Check alignment per steps on Page 3. Install
coupling per this manual using new gaskets and seals.
Periodic Lubrication
The required frequency of lubrication is directly related to the type
of lubricant chosen and the operating conditions. Steelflex
couplings lubricated with common industrial lubricants, such as
those shown in Table 1, should be re-lubed annually. The use of
Falk Long Term Grease (LTG) will allow relube intervals to be
extended 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 & 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.
Removal & Installation of Spacer Assembly
Remove Spacer Hub
Remove all but two fasteners opposite each other. Loosen these
about one-quarter inch and tap them with a mallet to disengage
spacer from the shaft hub. Remove fasteners and spacer.
Insert Spacer Hub
Insert fasteners as shown — do not allow them to protrude
beyond flange face. Insert spacer between hubs. Carefully
engage the hub register and then alternately tighten fasteners.
