FANSHAFT ASSEMBLY
The unit is equipped with a one-piece fanshaft assembly
that contains tapered roller bearings in a sealed oil reservoir.
This assembly does not require any maintenance. There is a
level plug and a fill plug, but they are not normally utilized
except after removal and repair of the fanshaft assembly.
The condenser end oil seal and the evaporator end oil seal
should be checked during the pre-trip inspection for oil
leakage. If there is any sign of leakage, the fanshaft assem-
bly should be removed and repaired.
NOTE: The fanshaft assembly requires a special lubri-
cant, TK P/N 203-278.
Fanshaft Assembly Overhaul

Remove the fanshaft assembly from the unit. Remove
both oil plugs and drain the oil from the housing.

2.
After draining the oil from the housing, remove the
four retaining bolts from the bearing retainer cap.
Removing Shaft
3.
To remove the shaft from the assembly, tap the opposite
end of the shaft with a soft hammer. After the shaft has
been removed, clean all parts in clean solvent.
Removing Oil Seal
4.
Using a punch, remove the oil seal from the evaporator
end of the assembly. With the seal removed, clean the
housing in solvent.
5.
Check the condition of the vent. If it is loose or dam-
aged, it must be repaired or replaced.
