2. Inspect both the driving and driven shafts
and coupling bores, making sure they are
free from burrs, scratches, and all foreign
matter. Be sure the keys fit the shafts and
coupling halves properly.
3. Since the coupling halves are mounted on
both the crusher countershaft and motor
shaft with an interference fit, heat the
coupling hub to a temperature of
approximately 96°C (175°F) above ambient
temperature and install on the shaft as
quickly as possible.
4. Measure the shaft diameter and the bore of
the coupling as it is being heated to be sure
the bore is slightly larger than the shaft. If
the coupling has been heated properly, no
trouble should be encountered in positioning
the coupling on the shaft. Make sure the
keyways are properly aligned.
5. Drive in the keys.
6. In order to provide the proper countershaft
end float using a direct drive arrangement, a
safety set collar has been installed on the
countershaft. See Figure 2-15.
7. Align the coupling as described in INITIAL
ALIGNMENT OF FLEXIBLE COUPLING.
NOTICE
Do not heat the coupling hub over 135°C
(275°F) as the flange or gap portion of the
coupling could become damaged from
excessive heat. A chemical marking device
which melts at a predetermined temperature
should be used to insure uniform and safe
heating.
WARNING
Use heavy well insulated gloves when
handling the heated coupling halves.

NOTICE
Recheck the end float by moving the
countershaft axially, in and out, as described
earlier in this manual.
