2. Loosen the clamp and remove the shroud.
3. Loosen the collet cap and remove the insert tool, cap and insert.
4. Use the 50971 Lock Ring Tool to remove the 02035 Lock Nut. Turn it counterclockwise.
5. Grasp the spindle and pull the 54520 Bearing and gear out of the angle housing.
6. Remove shims from housing if necessary.
7. Use the 96346 Bearing Separator and 96232 Arbor Press (#2) to remove the bearing and gear from the spindle.
8. If necessary, use a 5/16" dia. flat end drive punch as a press tool and the arbor press to remove the 02041 Plate, 01041 Gear Oil Fitting and the 02033 Needle Bearing.
Angle Housing Disassembly Complete.
Motor Disassembly:
1. Use the 52296 Repair Collar to secure the valve housing in a vise. Position the tool with the angle housing pointing up.
2. Use a 34 mm or an adjustable wrench to remove the 01461 Lock Ring. Turn it clockwise.
3. Pull the motor assembly out of the valve housing.
4. Fasten the 96346 Bearing Separator around the portion of the 01476 Cylinder that is closest to the 02676 Rear Bearing Plate.
5. Place the bearing separator on the table of the arbor press with the pinion gear pointing down.
6. Use a 3/16" dia. flat end drive punch as a press tool to push the rotor out of the 02696 Bearing. Remove the cylinder and vanes.
7. Use the 96210 Bearing Removal Tool and the arbor press to remove the 02696 Bearing from the 02676 Rear Bearing Plate.
8. Use a vise with bronze or aluminum jaws to secure the body of the rotor. Position the rotor with the pinion gear pointing up.
9. Use a wrench to remove the pinion gear from the rotor. Turn it counterclockwise.
10. Push the 02649 Bearing out of the front bearing plate and remove the shims.
11. Remove the 01479 Spacer from the rotor.
Motor Disassembly Complete.
Valve and Muffler Disassembly:
1. Position the 52296 Repair Collar around the valve housing and secure the tool in a vise so that the 94523 Inlet Adapter is pointing up.
2. Use a wrench to hold the inlet adapter stationary when removing the air fitting.
3. Remove the 94523 Inlet Adapter. Turn it counterclockwise.
4. Use the exploded view of the 94519 Muffler Assembly in this tool manual for the order of disassembly and part number identification. Be careful; do not
lose the air control ring.
5. Use needle nose pliers to remove the 01468 Spring and the 01472 Tip Valve. Use a small screwdriver to remove the 01464 Seal.
6. Position the valve housing so that the 12132 Pin, 01462 Safety Throttle Lever, and 01449 Valve Stem can be removed.
7. Use retaining ring pliers to remove the 95558 Retaining Ring and then push the 01469 Speed Regulator out of the valve housing.
Valve and Muffler Disassembly Complete.
Important: Clean and inspect parts for wear or damage before assembling.
Valve and Muffler Assembly:
1. Install the 01469 Speed Regulator Assembly into the valve housing and secure it with the 95558 Retaining Ring.
2. Use the 52296 Repair Collar to secure the valve housing in a vise with the air inlet pointing up.
3. Insert the 01449 Valve Stem into the speed regulator so that the hole in the valve stem aligns with the air inlet hole in the valve housing.
4. Install the 01464 Seal so that it lays flat. Use needle nose pliers to grasp the nylon portion of the 01472 Tip Valve and insert the metal pin into the hole of the
01449 Valve Stem.
5. Install the 01468 Spring with the small end against the back of the tip valve.
6. Refer to the parts breakdown for part identification and the sequence of assembly for the muffler. Apply a small amount of Loctite #567 (or equivalent) to the male threads
of the inlet adapter and install the muffler assembly. Tighten the inlet adapter. (Torque to 23 N•m/200 in. lbs.)
Valve and Muffler Assembly Complete.
Motor Assembly:
1. Secure the body of the rotor in a vise with bronze or aluminum jaws with the threaded end pointing up.
2. Slip the 01479 Spacer onto the 02037 Rotor.
3. Select .003" (.08mm) thick shims from the 54529 Shim Pack and place these into the 01478 Front Bearing Plate.
4. Install the 02649 Bearing into the front bearing plate and slip the bearing/plate assembly onto the rotor.
5. Install the pinion onto the rotor making it hand tight.
6. Check the clearance between the rotor and the bearing plate with a .001" (0.03 mm) thick feeler gauge. Clearance should be .001" to .0015" (0.03-0.04mm). If necessary
readjust clearance by repeating steps 3-5 with different shim thickness.
7. Once the proper rotor/plate clearance is achieved, wrench-tighten the pinion. (Torque to 17N•m/150 in. lbs.)
8. Apply the 95842 Dynabrade Air Lube 10W/NR (or equivalent) to the 01480 Vanes and install them into the rotor.
9. Use the 96242 Bearing Press Tool so that it pushes against the outside race of the 02696 Bearing and install it into the 02676 Rear Bearing Plate with the arbor press.
10. Place the pinion on the tool plate of the arbor press with the rear portion of the rotor pointing up.
