VERTICAL SHAFT BEARING REPLACEMENT
Vertical shaft bearings are much larger than the anemometer
bearings. Ordinarily, these bearings will last about twice as long as
the anemometer bearings. Check bearing condition holding the
instrument with the vane horizontal and placing a 3 gm weight near
the aft edge of the fin. A U.S. penny weighs about 3 gm and is
convenient for this check. Failure to rotate downward indicates the
vertical bearings need replacement. Repeat this test at different
positions to check full bearing rotation.
Since this procedure is similar to POTENTIOMETER REPLACE-
MENT, 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
9. REPLACE NOSE CONE
