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.
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 flush with the shaft end. Properly tighten
setscrews when furnished. For vertical shafts, seal the key-

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 speci-
fied in Table 1. Position equipment to obtain best alignment.
The measured difference between minimum and maximum
value should not exceed the angular limit specified in Table 1.
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 mechani-
cal connections are tightened.
3. Make sure all fasteners are properly installed and tight-
ened.
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 clarification or questions.

way to prevent grease leakage. For interference fit, 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 ex-
ceed the offset limit specified in Table 1.
