14. Use the large diameter end of the Bushing
Replacement Tool 204-1955 to press the new
bushing into the hub/coupling until the flange
on the bushing contacts the hub/coupling.
Press the new bushing into the hub/coupling
from side of the hub/coupling that faces the
flywheel (see Figure 206).
NOTE: Let the Loctite adhesive cure for at
least 1 hour at 70 F (21 C) before running
the unit. The components can be
reassembled immediately.
15. Inspect the clutch components before
reassembling the clutch and replace them if
necessary.
16. Install the friction shoes, mounting bolt plate,
and friction shoe mounting bolts. See shoe
installation instructions above (page 124).
17. Torque the mounting bolts for the friction
shoes to 30 to 35 ft-lb (41 to 47 N•m).
18. Press the clutch pulley into the bearing.
19. Place the clutch on the compressor crankshaft,
align the keyways (use Keyway Tool
204-972), and insert the key to be flush with
the end of the crankshaft.
20. Install the special washer and the clutch
mounting bolt. Torque the clutch mounting
bolt to 90 ft-lb (122 N•m). Use the Clutch
Restraint Tool or an impact wrench.
21. Reinstall the compressor drive belt on the
clutch pulley.
22. Slide the compressor back into position and
install the mounting hardware.
NOTE: Do not place any kind of lubricant
on the outside of the dowel pins or on the
inside of the drive bushings. Lubricant
between the dowel pins and drive bushings
will cause premature wear.
23. Place the belt on the electric motor and idler
pulleys. Make sure the belt fits on the pulleys
correctly.
24. Turn the idler adjuster as needed to adjust the
belt to the correct belt tension setting.
25. Tighten the idler mounting bolt.
26. Check the belt tension setting and readjust if
necessary.
Dowel Pin Replacement
1. Remove the flywheel.
2. Press the old dowel pins out of the flywheel.
3. Use the Manual Pin Tool or the Impact Pin
Tool to press or drive the new dowel pins into
the flywheel. The end of each dowel pin
should be 1.18 in. (30.0 mm) from the outer
face of the flywheel. The proper dimension is
critical and is set by using either of the tools.
CAUTION: Do not place the key on the
compressor crankshaft before installing
the clutch because the key might be
pushed out of place behind the clutch
when the clutch is installed.
