Assembly/Disassembly Instructions – .4 hp/7˚/Industrial DynaZip (cont.)

2. Select .003" (.08mm) thickness shims from the 54529 Shim Pack and install these into the 01478 Front Bearing Plate.

3. Install the 02649 Bearing into the 01478 Front Bearing Plate.

4. Position the rotor in the 96232 Arbor Press (#2) so that the pinion gear is pointing up. Place the front bearing/plate onto the pinion of the rotor and use

the raised center of the 96240 Bearing Press Tool to install these onto the rotor.

5. Use a .001" (0.3mm) thick feeler gauge to check the clearance between the front bearing plate and the face of the rotor.

6. The clearance should be .001"-.0015" (0.3-0.4mm). Note: If the clearance needs adjustment, repeat steps 2-4 adding or removing shims as required.

7. Lubricate the 01480 Vanes with the 95842 Dynabrade Air Lube 10W/NR (or equivalent) and install these into the rotor.

8. Install the 01476 Cylinder over the rotor so that the air inlet opening of the cylinder will line up with the air inlet opening in the 02673 Rear Bearing Plate.

9. Use the raised outer diameter of the 96242 Bearing Press Tool and the arbor press to install the 02696 Bearing into the 02673 Rear Bearing Plate.

10. Use the raised inner diameter of the 96242 Bearing Press Tool and the arbor press to install the rear bearing/plate onto the rotor.

Note: Carefully press the bearing/plate down until it just touches the cylinder. This will establish a snug fit between the bearing plates and the cylinder.

11. Apply a small amount of petroleum lubricant onto the seal of the 02696 Bearing and install the 02679 Shield so that it will stick against seal

of the bearing.

12. Carefully slide the motor assembly into the 50776 Housing.

13. Install the 50778 Spacer so that the flat side is against the 02649 Bearing.

Motor Assembly Complete. (Note: See Final Assembly)

Planetary Gear Assembly:

1. Use the 96232 Arbor Press (#2) and the raised center of the 96240 Bearing Press Tool to install the front 54552 Bearing onto the threaded end of the

planetary carrier.

2. Carefully fasten the solid part of the planetary carrier in a vise with aluminum or bronze jaws so that the end of the planetary carrier and the bearing are

pointing up.

3. Apply a small amount of the Loctite

Install the 13324 Adapter onto the planetary carrier. (Torque to 17N•m/150 in. lbs.)

4. Apply a small amount of the Lubriplate

5. Apply a small amount of the Lubriplate

the set screw and lubricant fitting in the 50776 Housing.

6. Use the 96232 Arbor Press (#2) and the raised center of the 96240 Bearing Press Tool to install the rear 54552 Bearing onto the end of the planetary

carrier. Note: Carefully press the bearing down until it just touches the ring gear. This will establish a snug fit between the bearings and the ring gear.

Planetary Gear Assembly Complete. (Note: See Final Assembly)

Please allow 30 minutes for adhesives to cure before operating tool.

Final Assembly:

1. Carefully install the planetary gear assembly. Align the notches in the ring gear with the set screw and lubricant fitting in the housing.

2. Apply a small amount of the Loctite

3. Apply two plunges of the 95542 Grease with the 95541 Lubricant Gun into the lubricant fitting.

4. Apply a small amount of the Loctite

(Torque to 28N•m/250 in. lbs.)

5. Use the 95262 Wrench (14 mm) to hold the 13324 Adapter stationary and install the 92284 Hub Assembly.

Final Assembly Complete.

Throttle Positioning Procedure:

Important: Carefully perform this procedure without entirely separating the 50776 Housing from the valve housing. Loosen the 01461 Lock Nut

only enough to make the desired throttle lever adjustment.

1. Place the 52296 Repair Collar around the valve housing and fasten it in a vise so that the 50776 Housing is pointing up.

2. Slip the 01558 Collar down onto the valve housing to expose the 01461 Lock Nut.

3. Use an adjustable wrench to hold the 13326 Housing Extension Adapter stationary while using a 34 mm Open-End Wrench or an adjustable wrench to

turn the lock nut clockwise to loosen the housing extension adapter from the valve housing.

4. Orient the throttle lever to the operators desired grip and positioning. Note: Allow for additional rotation of the 13326 Housing Extension Adapter

Housing as the 01461 Lock Nut is tightened. (Position throttle lever so tool will not activate, or accidentally start up, when at rest.)

5. Hold the 13326 Housing Extension Adapter stationary. Use a 34 mm Open-End Wrench or an adjustable wrench to tighten the 01461 Lock Nut.

(Torque to 45 N•m/400 in. lbs.)

6. Slip the 01558 Collar back over the 01461 Lock Nut.

Tool Assembly Complete. Please allow 30 minutes for the adhesives to cure before operating tool.

Important: The motor should be tested for proper operation.

Apply 3 Drops of the 95482 Dynabrade Air Lube 10W/NR (or equivalent) into the air inlet adapter with the throttle lever depressed. Carefully connect the tool

to an air supply. The tool should operate within 10% of the maximum rated RPM. The tool RPM should not exceed the maximum rated RPM with an operating

air supply pressure of 90 PSIG (6.2 bar g).
