MOTOR ASSEMBLY
1. Begin by lightly oiling the internal bore of
the turbine housing (14) with hydraulic oil
and fitting two inner o'rings (17).
2. Evenly press home bearings (18) until they
bottom. Ensure o'ring (17) is not damaged
or dislodged.
3. Install piston ring (16) onto seal sleeve (15).
Rotate piston rings (16) so that the gaps
are 180° apart.
4. Lightly grease the outside of the piston
rings (16) on the seal sleeve (15) and push
home into the turbine housing (14) until it
bottoms.
5. Press bearing (20) onto rotor shaft (19)
using a press and liberally grease top of
bearing.
6. Install third o'ring (17) into turbine housing
(14) and insert rotor shaft (19) and bearing
(20) as an assembly.
achieved with an even push fit.
7. Insert circlip (21) with circlip pliers.
8. Fit turbine rotor (13) onto rotor shaft (19)
extension.
9. Lightly oil thread on rotor shaft (19)
extension and install washer (12) and
special nut (11). Tighten nut against the
turbine rotor (13) to a torque of 25-30 ft Ib.
(30-40Nm.) Prevent the turbine rotor (13)
from turning by using a ring spanner
(wrench) on the special flats provided.
10.Install o'ring (10) onto turbine housing (14)
and apply oil.

SILENCER ASSEMBLY
Assemble in the reverse order of disassembly.
Ensure baffle plate (6) moves freely under
compression of springs (4), Tighten nuts (1)
firmly.
ASSEMBLING NOSE & MOTOR ASSEMBLIES
1. Apply grease to planet gears (25) and
gear case (31). Carefully line up spline of
motor assembly shaft (19) with the planet
gears (25) on the nose assembly and slide
the nose assembly home.
2. Line up the nose assembly and motor
assembly air inlet ports and install band
clamp (8). Tighten band clamp (8) to 4 ft lb
(6 Nm).
3. Test the operation of the drive assembly
(40) by introducing air pressure at the
control line inlet port. The drive assembly
should move freely forward when air
pressure is applied and back once the
pressure has been relieved. Investigate if
this movement is not smooth.
The nose/motor assembly is now ready to
accept the silencer assembly.
ADDING SILENCER ASSEMBLY
1. Install silencer assembly to the turbine
housing (14). Install band clamp (8).
Tighten band clamp (8) to 4 ft lb (6Nm).
2. The AUSTART Air Starter is now assembled
and
