SERVICE INSTRUCTIONS FOR 15G MOTOR & GOVERNOR
15G MOTOR & GOVERNOR
*These parts can be purchased as a subassembly using number: 861176
DISASSEMBLY
Clamp the cylinder 864236, lightly in a soft jawed vise and tap the rotor
865694, out of the front rotor bearing 865658. This will allow the front
rotor bearing, front bearing plate, 865693, rotor collar, 865657, cylinder,
and rotor blades, 864234, to be removed from the rotor. Clamp the rotor
in the vise and unscrew the governor (left hand threads). The governor
adjusting screw, 867086, may now be removed from the rear of the
rotor.
REASSEMBLY
The motor is reassembled in the reverse order of disassembly. Wash
all parts thoroughly ina solvent and visually inspect for damage or wear.
Check bearings for wear which can be detected by excessive end play,
or roughness of the bearings which indicates a brinelled condition. Pack
both rotor bearings with a good grade of No. 2 Moly Grease. Particular
attention should be paid to the governor assembly, replacing any of its'
parts that show wear or damage. It is recommended that new rotor
blades be installed at each repair cycle. If not replaced, the used ones
must measure a minimum of 7/32" (5.5mm) at both ends.Failure of
these parts could cause damage to more expensive components. Also,
be sure that the blades are no longer than the rotor.
The rotor in this tool must be set by means of the rotor collar, 865657,
so that when assembled, there is .0015" clearance between the front
end of the rotor and the face of the front bearing plate To properly set
the rotor collar, assemble the front bearing (shield toward backhead)
into the front bearing plate. Measure the depth of the inner race from the
face of the bearing plate. Select, or fit by sanding, an rotor collar .0015"
larger than this dimension. Governor center 865687, governor weights
865663, and governor pins No. 867388, should be checked periodically
for wear and replaced if excessively worn.
