5. Turn the air motor assembly clockwise
to separate it from the motor mount.
NOTE: The air motor has left-hand
threads.
6. Unscrew the gear housing (30) from the
motor housing.
7. Slide out the cylinder (15) from the
motor housing (11). When reinstalling
the cylinder in the motor housing be
sure to line up the alignment pin (16)
with the aligning mark on the housing.
This will ensure that the alignment pin
will slip into the correct hole in the
bottom of the motor housing.
8. Remove each of the idler gear
assemblies (23) from the cage (24).
Check the idler pins, the bushing in the
center of the idler gear, and the pinion
shaft teeth for wear. Replace if
necessary.
9. Remove the aligning pin and tap on the
end of the rotor (18) to loosen the
assembly.
10. Disassemble the rotor by sliding off the
front end plate (20), and the two ball
bearings and spacer (21, 22). Then slide
the back end plate (14) and the rotor
assembly (18), with the vanes (17), out
of the cylinder.
11. Look for areas of wear on the face of
the end plates, the pinion teeth on the
rotor and the edges of the vanes. The
vanes must be kept clean to float freely
in the rotor. Note: If the vanes and/or
the idler assemblies have to be
replaced, they must soak in air line oil
overnight before assembling them into
tool.
12. Once these parts have been examined,
cleaned and worn parts replaced, the
air motor may be reassembled. Keep in
mind the care required when
reassembling the alignment pin.
13. Temporarily install the O-ring (34) and
the valve housing assembly to the air
motor housing.
14. Add several drops of air line oil to the
motor. Lightly clamp the air motor into
a traditional vise. Connect air to the
motor at 20 psig and press the motor
lever. The motor must start and turn
freely. With the motor running, carefully
tighten the gear housing (30) by turning
clockwise and note the speed increase
to peak RPM using 275-450 in. lbs. of
torque. Do not over tighten as this will
slow down the motor. Disconnect air
supply.
