• Read and follow all instructions carefully.
• Disconnect and lock-out power before installation and maintenance.
Working on or near energized equipment can result in severe injury or death.
• Do not operate equipment without guards in place. Exposed equipment can
result in severe injury or death.

Installation and Alignment Instructions
These instructions apply to KOP-GRID® tapered grid couplings.
This sheet may be supplemented by Special Instructions supplied with
the coupling for modications and variations of these couplings. For
dimensions, ratings, maximum bores, interference ts, and other technical
information, please refer to catalog MCC11001E.
When working on rotating equipment be sure to lock out the starting
switch of prime mover so the equipment cannot be started until work is
complete, checked, and personnel are safely away. Proper installation per
this product instruction sheet must be observed. Failure to do so may void
warranty and could result in injury to person or property.
Maintenance and Lubrication
Lubricate the KOP-GRID coupling with grease only. Use KOP-FLEX KSG
coupling grease or other grease meeting the minimum specications
shown.
Do not use oil in KOP-GRID couplings.
Coupling lubrication is critical. The use of proper and sufcient lubrication
is part of a successful installation. Lubricants should be checked to
ensure the proper level is maintained and that the lubricant is free of
contaminates. In an average industrial application, the coupling should
be checked for lubricant contamination and replenished with the proper
volume every twelve months. Conditions such as very slow speed,
reversing drives, high heat and severe environments may require more
frequent lubrication.
COVER
FASTENERS
• Periodic inspections should be performed. Failure to perform proper maintenance
can result in premature product failure and personal injury.
Recommended Lubricant
KOP-FLEX
This grease is specically compounded for standard couplings to provide
improved lubrication and resistance to centrifugal separation. When
KSG grease is used, lubrication intervals may be extended, based upon
operating experience. KSG coupling grease is available from Kop-Flex or
authorized distributors of Kop-Flex power transmission products.
®
KSG Coupling Grease
Other Greases
Alternate lubricating greases should equal or exceed the specications for
KOP-FLEX KSG coupling grease. Greases other than KSG should meet
these minimum specications:
Grade: NLGI #1
Base oil Viscosity: Min:
1500 SSU at 100°F
100 SSU at 210°F
Dropping Point, Min.: 190°F
Four Ball Wear, ASTM D-2266:
.85 mm Maximum
Base Oil Content: 87% Minimum
K36 Factor, ASTM D-4425:
KSG: K36 = 8/24 =.33
Required:
Rust and Oxidation Inhibitors
E.P. Additives
The most reliable test of a suitable lubricant is often the result of user
experience and satisfaction. If a lubricant has been known to sludge,
separate into heavy components or dry out, consider the use of KOP-
FLEX KSG grease.
WARNING! Failure to observe safety precautions could cause
personal injury or equipment damage.
Important Safety Instructions
Before start-up for reasons of safety and to extend shaft coupling life,
follow these requirements.
1. Coupling guards protect personnel. ALL COUPLINGS MUST BE
COVERED WITH A GUARD AS PER OSHA REQUIREMENTS.
2. Recheck alignment after all foundation bolts and mechanical
connections are tightened.
3. Make sure all fasteners are properly installed and tightened.
4. Take the time to double check your work.
5. Only authorized Kop-Flex replacement parts are to be used.
6. Call Kop-Flex for any clarication or questions.

1. Hub Installation
Verify all parts are on hand and are as ordered, check that the
hub bores are correct. Prepare shafts by removing dirt and burrs.
Lightly apply grease on seals and place them on shafts, before
installing the hubs. Mount the hubs on their shafts, with hub
face ush with the shaft end. Properly tighten setscrews when
furnished. For vertical shafts, seal the keyway to prevent grease
leakage. For interference t, heat the hub in an oven to 300°F
(150°C) before mounting the hub. NEVER exceed 600°F (300°C).
Note: Allow heated hubs to cool to room temperature before
coupling alignment and assembly.
3. Offset Alignment
Use a straight edge and feeler gauge to align shafts at 4 points
90° apart. The offset (parallel misalignment) should not exceed
the offset limit specied in Table 1. Adjust equipment as required.
Recheck steps 2 and 3 after tightening the foundation bolts and
realign the coupling, if the offset and angular measurements
exceed the values in Table 1. Note: Best coupling alignment
is obtained by using dial indicators. If dial indicators are used,
always rotate the hub on which the indicator is mounted to obtain
readings.
Figure 2 Figure 4
2. Shaft Separation & Angular Alignment
Use a feeler gauge to measure the gap between hub faces at 4
points 90° apart. The gap should not exceed the value specied
in Table 1. Position equipment to obtain best alignment. The
measured difference between minimum and maximum value
should not exceed the angular limit specied in Table 1.

4. Tapered Grid Installation
Fill the hub gap and grid teeth grooves with KOP-FLEX® KSG
grease or a comparable alternate. Lightly open the grid to engage
with the grooves on the hub. Use a soft mallet to seat the grids
in the tapered teeth grooves. For tapered grids that are supplied
with more than one segment, make sure all the segment’s open
ends are on the same side.
