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 pretrip inspection for oil leakage. If there is
any sign of leakage, the fanshaft assembly should
be removed and repaired.
NOTE: The fanshaft assembly requires a special
lubricant (see Tool Catalog).
Disassembly
1. 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.
