VERTICAL SHAFT BEARING REPLACEMENT
Vertical shaft bearings are much larger than the anemometer
bearings. Ordinarily, these bearings require replacement less
frequently than anemometer bearings. Check bearing condition
using a Model 18331 Vane Torque Gauge.
Since this procedure is similar to POTENTIOMETER
REPLACEMENT, only the major steps are listed here.
1. REMOVE MAIN HOUSING
2. UNSOLDER TRANSDUCER WIRES AND REMOVE
TRANSDUCER ASSEMBLY
Loosen set screws at base of transducer assembly and
remove entire assembly from vertical shaft.
3. REMOVE VERTICAL SHAFT BEARING ROTOR by sliding
it upward off vertical shaft.
4. REMOVE OLD VERTICAL BEARINGS AND INSTALL
NEW BEARINGS. When inserting new bearings, be careful
not to apply pressure to bearing shields.
5. REPLACE VERTICAL SHAFT BEARING ROTOR.
6. REPLACE TRANSDUCER & RECONNECT WIRES
7. REPLACE MAIN HOUSING
8. ALIGN VANE
