NOTE: If disassembling a tool with the
alternate style locking ring, use socket
adapter Part No. 422341.
6. Turn the air motor assembly clockwise to
separate it from the motor mount. NOTE:
The air motor has left-hand threads.
7. Unscrew the gear housing (30) from the
motor housing.
8. 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.
9. Remove each of the idler gear assemblies
(23) from the cage (24). Check the idler
pins, the bushing in the center of idler
gear, and pinion shaft teeth for wear.
Replace if necessary.
10. Remove the aligning pin
and tap on the end of the
rotor (18) to loosen the
assembly.
11. Disassemble the rotor by sliding off the
front end plate (20), and any ball
bearing(s) and spacers. Then slide the
back end plate (14) and the rotor
assembly (18), with the vanes (17), out of
the cylinder.
12. Loo
k 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.
13. 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.
14. Temporarily install the O-ring (34) and the
valve housing assembly to the air motor
housing.
15. 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.
