Shims and O-ring

Install the retainer cap assembly over the shaft, and
then install the bolts.
6.
Torque the bolts in a criss-cross pattern in equal steps to
80 in-lbs (9.04 N•m).
Torquing Retainer Plate Bolts
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
opposite direction while reading the dial indicator. The
end play should be 0.001 to 0.005 in. (0.025 to
0.127 mm). If the end play is incorrect, use different
shims to obtain the correct end play.
Shims available from the Service Parts Department:
0.020 in. (0.500 mm)
P/N 99-4231
0.007 in. (0.177 mm)
P/N 99-2902
0.005 in. (0.127 mm)
P/N 99-2901
Checking End Play
8.
After the correct end play is obtained, add grease for
the bearings.
NOTE: Use ONLY Thermo King special fan shaft
grease (P/N 203-278) in this assembly.
Lock the assembly in a vise with the vent facing up.
Pour grease through the top plug until it runs out of the
side hole. The assembly holds 2.2 oz (65 ml). Check
the condition of the O-ring used on the plugs and
replace if necessary. Install top and side plugs. Clean up
any spillage.
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.
