Compressor Coupling Removal
(Model 30)
1.
After the compressor has been removed from the unit,
use the appropriate Allen tool provided with removal
tool P/N 204-991 to loosen the center bolt which holds
the coupling to the compressor shaft.
2.
Attach the tool to the coupling with the provided socket
head screws and spacers. 2 sets of spacers are provided
with the tool, use the short spacers with shallow com-
pressor mounting flanges and the longer set for deeper
flanges. The side with the countersunk holes should be
toward the coupling.
3.
To prevent the tool and crankshaft from rotating, use
one of the compressor to engine mounting screws to pin
the tool to the flange. If a nut is used to prevent the bolt
from falling out, the nut should not be tightened.
4.
Use torque wrench and the appropriate Allen tool to
unscrew the coupling mounting screw. Apply a maxi-
mum of 90 ft-lb of torque to the screw.
5.
Once the center screw has been loosened, back the head
against the tool and it should push the coupling off the
crankshaft as you continuing turning the center screw
in a counter-clockwise direction. Using this tool will
prevent the coupling from popping off because the cen-
ter bolt and flatwasher will hold it in place.
