7.
Lock the assembly in a vise and set up a dial indicator to
read the end play. To measure the end play, rotate the
shaft while pushing in one direction, and set the dial
indicator to 0. Now rotate the shaft and pull in the oppo-
site direction while reading the dial indicator. The end
play should be 0.025 to 0.127 mm (0.001 to 0.005 in.).
If the end play is incorrect, use different shims to obtain
the correct end play.
Shims available from the Service Parts Department:
0.500 mm (0.020 in.)P/N 99-4231
0.177 mm (0.007 in.)P/N 99-2902
0.127 mm (0.005 in.)P/N 99-2901
8.
After the correct end play is obtained, add oil for the
bearings.
NOTE: Use ONLY Thermo King special fan shaft oil
P/N 203-278 in this assembly.
Lock the assembly in a vise with the vent facing up.
Pour oil through the top plug until it runs out of the side
hole. The assembly holds 65 ml (2.2 oz). Check the
condition of the O-ring used on the plugs and replace if
necessary. Install top and side plugs. Clean up any spill-
age.
9.
Place the assembly on the workbench with the vent up.
Rotate the shaft by hand. The shaft should be free
enough to rotate without having to hold the housing.
CAUTION: When installing the fan shaft assembly,
make sure that the vent is mounted facing up.
Condenser Fan Positioning
When installing the condenser fan on the fan shaft, the fan
must be positioned correctly.
1.
Fasten the condenser fan hub and pulley together.
2.
Place the taper hub and the fan on the condenser hub
and install the taper hub bolts loosely.
3.
Slide the fan assembly on the fan shaft until there is
only enough clearance between the pulley and the bulk-
head to allow the fan to rotate. This will assure mini-
mum clearance when the taper hub bolts are tightened.
4.
Tighten the taper hub bolts in a criss-cross pattern to 20
to 23 N•m (15-17 ft-lb).
5.
Check the clearance between the taper hub and the fan
hub. A minimum clearance of 2.5 mm (0.10 in.) assures
the taper hub is properly seated.
