Notice: To avoid damaging the motor housing, use the Special Repair Tool that is designed for disassembly and assembly of these die grinders. See page 8 for a complete list
of available repair tools.
Disconnect the die grinder from the air supply.
Motor Disassembly:
1. Secure the air inlet adapter of the die grinder in a vise with aluminum or bronze jaws so that the collet assembly is pointing up.
2. Use 14 mm open-end wrenches to remove the collet assembly.
3. Use an adjustable wrench to remove the 53152 Adapter. Turn counterclockwise.
Note: One of two things will occur.
A. The 53152 Adapter will loosen. If this occurs, remove it and then remove the air motor assembly by pulling the motor out of the housing. Remove the filter cage and filter. Insert
the hex end of the 96402 Special Repair Tool into the hex socket in the bottom of the housing. Use an adjustable wrench to loosen the housing from the air inlet adapter.

"Tear-Drop End"
B. The air inlet adapter will loosen. If this occurs, remove the air inlet adapter, muffler and valve components.
Remove the 2 valve seals (Fig.1). Insert the "Tear-Drop End" of the 96402 Special Repair Tool into the air inlet of the housing. Place the hex end of the special repair tool in a
vise with aluminum or bronze jaws so that the housing is pointing up (Fig. 2 & 3). Use an adjustable wrench to remove the 53152 Adapter. Turn counterclockwise.
4. Use the 50971 Lock Ring Tool and an adjustable wrench to separate the 53152 Adapter from the rear exhaust cover or planetary housing. Turn counterclockwise. Use a
5/64" hex key to remove the 50784 Set Screw(s). Remove the planetary gear assemblies.
5. Remove the air motor.
6. Carefully secure the pinion in a vise with aluminum or bronze jaws so that the governor assembly is pointing up. Use a slot blade screwdriver to remove the governor. LEFT
HAND THREAD: Turn clockwise. Note: The governor assembly is not serviceable. If the governor fails it must be replaced as a complete assembly.
7. Fasten the 96346 Bearing Separator (2") around the portion of the 01476 Cylinder that is closest to the 02673 Rear Bearing Plate. Place the bearing separator and the motor
in the 96232 Arbor Press (#2) with the pinion pointing down.
8. Use a 5/32" (4 mm) diameter flat end drive punch as a press tool to push the rotor out of the 02696 Bearing.
9. Remove the cylinder and vanes.
10. Use the 5/32" (4 mm) diameter flat end drive punch to push the 02696 Bearing out of the 02673 Rear Bearing Plate.
11. Use the 96232 Arbor Press (2#) to remove the 01478 Front Bearing Plate, 02649 Bearing, shims, and 01479 Spacer.
Motor Disassembly Complete.
Planetary Gear Disassembly
1. Important: Position the 96346 Bearing Separator (2") with the FLAT SIDE facing the RING GEAR and the BEVELED SIDE toward the REAR 54520 Bearing. Place the bearing
separator and the planetary gear assembly in the 96232 Arbor Press (#2) with the 50782 Adapter or 53150 Pinion pointing down.
2. Use a 5/16" flat end drive punch as a press tool to push the planetary carrier out of the REAR 54520 Bearing.
3. Remove the ring gear, shafts, and planet gears.
4. Carefully secure the planetary carrier in a vise with aluminum or bronze jaws with the 50782 Adapter or 53150 Pinion pointing up.
5. Use a Heat Gun to warm the adapter or the pinion. This is to soften the thread adhesive. Use an adjustable wrench to remove the adapter, or a 3 mm diameter pin to remove
pinion from the planetary carrier. Turn counterclockwise.
6. Use the arbor press and a 5/16" flat end drive punch as a press tool to push the planetary carrier out of the remaining 54520 Bearing.
Planetary Gear Disassembly Complete.
Clean and inspect all parts before assembling.
Motor Assembly:
1. Install the 01479 Spacer onto the rotor.
