DESIRED FORWARD ROTOR SPEED
At the selected speed setting (80, 160, 320, or 650) the
rotor speed should be 8200 - 9700 RPM.
The motor speed should change smoothly as the speed
is adjusted step by step.
Reverse rotation (rapid advance lever depressed)
should be 5,700 RPM minimum.
If shims are lost, or rotor speed is improper, remove
motor unit and clamp in vise with the governor
assembly upward and the governor weights leaning
inward. Add or adjust shims 864732 and 869562 to
provide this clearance:

Reassemble and run motor. If the desired forward rotor
speed is still not acceptable (8200 - 9700 RPM); disas-
semble motor backhead and add shims 203349 under
governor spring 382238 to increase speed, or remove
shims to decrease speed.
Continue reassembly same as single speed tools
FINAL REDUCTION ASSEMBLY:
Reassemble in the reverse order of disassembly.
Grease all parts with a good grade of NLGI 2-EP
grease. Install the washer and ball bearing 864471 on
the front of the output spider. Clean the threads on the
spider and pinion gear 382461. Hold a large hex wrench
or similar tool on the side of the spider and clamp in the
vise. Apply a thread locking liquid to the threads and
screw the pinion into the spider (tighten to approxi-
mately 60 ft. Ibs.—81.4N). Use Tool Maintenance Kit for
easier assembly.
HEAD REASSEMBLY:
UPPER BLOCK: The retract valve must slide
freely (without O-ring) by its own weight inside the bore.
Lubricate and assemble O-ring 844306, retract valve
382333, spring 382540, and tighten valve cap 382331.
Press (press on the bearings stamped end) the needle
bearing 617253, into the rear of the gear stop 382547.
The bearing should be flush with face. Assemble O-ring
863009, on feed piston 382548 lubricate and fit into
bore. Piston should move with finger tip pressure. Press
the gear stop into bore. Apply a drop of thread locking
liquid on the two (2) screws 812667 and tighten them.
