MOTOR REASSEMBLY
1. Install ball bearings into both the front and rear plates.
2. Assemble rotor to rear plate/bearing assembly with the rotor’s retaining nut.
Position and set the rotor as close as
possible to the rear plate, without dragging or rubbing.
a. A good practice is to stone the blade slots and polish the ends with a medium grit emery cloth.
b. Assemble components making sure the bearing is firmly seated in the rear plate.
a. One method, shown at right, is to use a piece of
pipe which is slightly longer than the rotor, and
tap lightly against work bench several times.
This helps seat threaded components.

CLEARANCE
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.
b. A second method is to hold the rotor/rear plate
assembly vertically (plate downward) and strike
the edge of the plate with a wood block.
Recommended Spare Parts List for
BUCKEYE Series 21D Drills
These parts are suggested as a recommended inventory of spare parts. Where parts are small, low cost, or
easily lost, then we suggest stocking 3 to 4 for every 10 tools. Other larger, lower wear or more expensive
parts should be maintained as one (or one set) for every six to ten tools.
