15. Use the 96240 Bearing Press Tool and the 96232 Arbor Press (#2) to install the 12153 Bearing onto the shorter stem of the planetary carrier. Note: Position the press tool
against the inner race of the bearing when pressing the bearing onto the stem of the planetary carrier.
16. Install the 02579 Key into the longer stem of the planetary carrier.
17. Use the 96240 Bearing Press Tool to support the inner race of the 12153 bearing that is on the shorter stem of the planetary carrier. Place the opposite side of the 96240
Bearing Press Tool on the table of the arbor press. Align the 02578 Yoke on the longer stem of the planetary carrier and to the 02579 Key. Press the yolk down onto
the planetary carrier.
18. Install the 02582 Retaining Ring so that it is arched away from the 02578 Yolk.
19. Install the 02583 Crank into the 02578 Yoke. Index the crank to the number 6 setting. Apply a small amount of the Loctite #567 (or equivalent) to the threads of the
96071 Set Screw and secure it into the 02583 Crank with the 95266 Hex Key (3mm).
20. Apply a small amount of the Loctite #609 (or equivalent) to the outer race of the 02587 Bearing and install the bearing into the 02586 Wrist Pin Coupler.
21. Apply a small amount of 95848 Gear Oil into the 02587 Bearing and install the wrist pin coupler along with the bearing onto the 02584 Dowel Pin.
22. Install the wrist pin coupler along with the bearing onto the 02584 Dowel Pin.
23. Apply a small amount of the Loctite #271 (or equivalent) to the threads of the 02522 Ball Joint and install it into the 02520 Slider. Align and thread the ball joint into the
wrist pin coupler securing it in place with the 96314 Open End Wrench.
24. Install the 02581 Cover onto the 02514 Housing and turn it clockwise to secure it in place.
25. Initially lubricate the planetary gears with the 95848 Gear Oil applying 2-3 plunges of oil with the 95541 Gear Oil Gun. After the initial application of oil lubricate the
gears with 2-3 plunges for every 8 hours of use.
Work Head Assembly Complete.
Valve Assembly:
1. Place the 52296 Repair Collar around the 12257 Housing and secure the tool in a vise so that the air inlet opening is pointing up.
2. Install the 01469 Speed Regulator along with the 01449 Valve Stem and secure the speed regulator assembly with the 95558 Retaining Ring.
3. Install the 01464 Seal into the air inlet so that it is laying flat.
4. Use needle nose pliers to install the 01472 Tip Valve so that the metal pin fits through the hole in the 01449 Valve Stem.
5. Install the 01468 Spring so that the small end fits over the back of the tip valve.
6. Install the inlet adapter into the 12257 Housing. Note: Refer to the exploded view of the muffler assembly to identify the parts and their correct order of assembly.
Apply a small amount of the Loctite #567 (or equivalent) to the threads of the 01578 Inlet Adapter and install it into the 12257 Housing.
7. Install the throttle lever and secure it in place with the 12132 Pin.
8. Use two wrenches when installing the 94407 Flow Control Swivel and the air fitting. Place one wrench on the 01578 Inlet Adapter to hold it stationary and use another
wrench to install the 94407 Flow Control Swivel and air fitting.
Valve Assembly Complete.
Motor Assembly:
1. Secure the vane body of the rotor in a vise with aluminum or bronze jaws so that the pinion end is pointing up.
2. Slip the 01479 Spacer onto the 02504 Rotor.
3. Place a .002 (.05mm) thick shim from the 54529 Shim Pack into the 02507 Front Bearing Plate as an initial spacing and install the 02649 Bearing into the front bearing plate.
4. Use the 96240 Bearing Press Tool so that it pushes against the inner race of the 02649 Bearing and with the 96232 Arbor Press (#2) install the bearing/plate assembly
onto the 02504 Rotor.
5. Use a .001 (.03mm) feeler gauge to check the clearance should be .001 (.03mm) - .0015 (.04mm). If it is necessary to make an adjustment to the clearance, do so by
repeating steps 3-5. (Changing the thickness of shims.)
6. Once the proper rotor/plate clearance is achieved, apply the 95842 Dynabrade Air Lube (10W/NR or equivalent) to the 02505 Blades (4) and install these into the rotor.
7. Use the 96216 Bearing Press Tool so that it pushes against the outer race of the 02696 Bearing and use the arbor press to install it into the 02676 Bearing Plate.
8. Install the 02506 Cylinder so that the air inlet passage of the cylinder is properly aligned with the air inlet passage in the 02676 Rear Bearing Plate.
9. Use the 96216 Bearing Press Tool so that it pushes against the inner race of the 02696 Bearing and use the arbor press to install the rear bearing/plate assembly onto the
02504 Rotor. Note: Carefully press the rear bearing/plate assembly onto the rotor until it touches the 02506 Cylinder. A "snug" fit should be created between the bearing
plates and the cylinder. If the fit is too tight the rotor will not turn freely and will cause damage to the bearings. If the fit is too loose the proper bearing
preload will not be achieved.
10. Apply a small amount of the 95848 Gear Oil to the seal of the 02696 Bearing and stick the 02679 Shield against the seal of the bearing.
11. Install the motor assembly into the 12257 Housing so that the air passage node of the rear bearing plate aligns with the air passage notch on the inside of the housing.
12. Apply a small amount of the Loctite #567 (or equivalent) to the threads of the 12257 Housing and use a 34mm or an adjustable wrench to secure the 01461 Lock Nut
when connecting the work head assembly to the motor housing. (Torque to 34 N•m/300 in.- lbs.)
Motor Assembly Complete. Tool Assembly Complete. Please allow 30 minutes for adhesives to cure before operating tool.
Throttle Lever Positioning Procedure:
1. Place the 52296 Repair Collar around the 12257 Housing and secure it in a vise so that the 02514 Housing is pointing up.
2. Slip the 01558 Collar down onto the 12571 Housing to expose the 01461 Lock Nut.
3. With a firm hold on the 02514 Housing, use a 34mm or an adjustable wrench to turn the 01461 Lock Nut counterclockwise to loosen the 02514 Housing from the valve housing.
4. Orient the throttle to the operators desired grip and positioning. Note: Allow for additional rotation of the 02514 Housing as the 01461 Lock Nut is tightened.
5. With a firm hold on the 02514 Housing to reduce its rotation, use a 34mm or an adjustable wrench to tighten the 01461 Lock Nut. (Torque to 45 N•m/400 in.- lbs.)
Important: Carefully perform this procedure so as not to entirely separate the 02514 Housing from the 12257 Housing. Loosen the 01461 Lock Nut only enough to make the
desired throttle lever adjustment.
