Fan Shaft Assembly
The unit is equipped with a one-piece fan shaft
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 used except after removal and repair
of the fan shaft assembly. The condenser and
evaporator end oil seals should be checked during
the pretrip inspection for oil leakage. If there is
any sign of leakage, the fan shaft assembly should
be removed and repaired.
NOTE: The fan shaft assembly requires a
special lubricant, Thermo King P/N 203-278.
Fan Shaft Assembly Overhaul
Disassembly
1. Remove the fan shaft 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
condenser end of the assembly.
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.
4. Using a punch, remove the oil seal from the
evaporator end of the assembly. With the seal
removed, clean the housing in clean solvent.
5. Check the condition of the vent. If it is loose
or damaged, it must be repaired or replaced.
6. After all the parts are cleaned, inspect the
bearings and bearing races for wear or
damage.
7. If necessary, remove the bearings by tapping
them off the shaft with a hammer and a punch.
Be careful not to damage the shaft with the
punch.
8. The bearing races can now be driven out with
a punch and replaced in the same manner.
