17. Place drop of medium strength thread locker on the
threads of each set screw. Using a 2.5 mm and a
4.0 mm Allen wrench, screw the set screws into the
shaft collar far enough so that the shaft collar can
slide on the compressor shaft sleeve. Rotate the
shaft collar so the pin faces up. Align the shaft collar
pin with the compressor shaft keyway as shown.
Slide the shaft collar onto the compressor shaft, pin
first.
18. Using a long screw driver, slowly rotate the fan
pulley. With the keyway of the coupler mounting
plate facing up, place the key into the shaft keyway
with the key slid to the end of the shaft keyway (as
shown). A light tap with a rubber mallet may be
needed to ensure the key seats completely.
19. Slide the compressor onto the coupler mounting
plate until the face of the compressor is flush with
the compressor bracket. Rotate the compressor 90
degrees clockwise so that the set screw access is
accessible.
NOTICE
Performing steps 19 through 23 out of order, or
incorrectly, may cause excessive side loading on the
compressor crankshaft and could cause a premature
failure of the compressor.
