3. Begin tightening rotor nut without over tightening to avoid
damaging the ball bearing. Alternately spin the rotor while
tightening until clearance is judged to be proper - about
0.001" clearance.
a. One method, shown at right, is to use a piece of
pipe which is slightly longer than the rotor, and tap
lightly against a work bench several times. This
helps seat threaded components.
b. A second method is to hold the rotor rear plate
assembly vertically (plate downward) and lightly
strike the edge of the plate with a wood block,
alternating sides.
PARTS INSPECTION
1. Wash all parts except ball bearings in solvent. Dry
and place on a clean cloth for inspection.
2. Check ball bearings for wear. Bearings should turn
smoothly with no appreciable shake or looseness.
3. Check rotor blades for wear by comparing with a new
blade. Replace if worn more than 1/32" in height.
4. Check motor cylinder for grooves, gouges or pitting.
Honing is permissible, however, never remove more than
about 0.001" or 0.002" of material. Replacement is
usually recommended.
