Output Spindle End - Disassembly
1. Disassemble the grips and plastic components..
2. For In-line and Pistol Models,
Using CPS2-25F-70 Fixture Plug, a Hook Spanner Wrench or
similar wrench to hold the tool, and using Spanner Wrench
CPS2-478 (or other appropriate wrench), unscrew Coupling
Nut (81).
Use caution while removing coupling nut. If spindle assembly
becomes disengaged from main housing keys spindle assembly
can rotate causing damage to the flex circuit. Spindle housing
must be held engaged with motor housing keys during nut
disassembly.
Remove the Spring (83).
3. For Angle and Fixtured Models,
Using CPS2-25F-70 Fixture Plug, a Hook Spanner Wrench or
similar wrench to hold the tool, and using Spanner Wrench
CPS2-478 (or appropriate wrench), unscrew Coupling Nut (92).
Note:
Left hand thread.
Remove the Angle Head (91) or In-line Attachment.
Remove the Lock Washer (104) off of Spindle Coupling (103).
Using a CPS2-25F-70 Fixture Plug, a Hook Spanner Wrench or
similar wrench to hold the tool, and using Spanner Wrench CPS2-
478 (or appropriate wrench), unscrew Spindle Coupling (103) off
Spindle Housing (102).
Note
: Left hand thread
Remove Light Ring Lens (106) off of Spindle Housing (102).
Using CPS2-25F-70 Fixture Plug, a Hook Spanner Wrench or
similar wrench to hold the tool, and using Spanner Wrench
CPS2-478 (or appropriate wrench), unscrew Coupling Nut (107)
off Motor Housing Assembly (1). Use caution while removing
coupling nut. If spindle assembly becomes disengaged from
the main housing keys the spindle assembly can rotate causing
damage to the flex circuit.

Remove Spindle Housing (102) .
If required, remove Flex PCB (105) from the Spindle Housing (102).
If required, Remove Retainer (99) off of Bit Holder Plug
Assembly (98).
If required, Remove Bit Holder (76).
Remove Hall Housing (72) from Spindle Housing (102).
Angle Attachment Disassembly
1. For 3/8” and 1/4” Square Drive Spindles,
Looking down hole of the Spindle’s square socket, locate
Retaining Pin (95) and Retaining Spring (94).
If necessary, use a pointed metal probe to pull retaining
Spring out of Spindle cavity.
If necessary, remove Pin from Spindle.
2. For Quick Change Spindles, remove Bit Retaining Spring (97)
and Bit Retaining Ball (96).
3. Using CPS2-25F-70 Fixture Plug, a Hook Spanner Wrench or
similar wrench to hold the tool, and using Spanner Wrench
CPS2-478 (or other appropriate wrench), unscrew Coupling
Nut (92) and pull the Angle Assembly Attachment (91) out of
Motor Housing Assembly (1).
4. If necessary, remove Coupling Nut Retainer (93) using an
appropriate tool.
In-Line Attachment Disassembly
1. Using CPS2-25F-70 Fixture Plug, a Hook Spanner Wrench or
similar wrench to hold the tool, and using Spanner Wrench
CPS2-478 (or other appropriate wrench), unscrew Coupling
Nut (92) and pull the In-Line Attachment out of Motor Housing
Assembly (1).
2. If desired, remove Coupling Nut Retainer (93) using the
appropriate tool.
Note
: In the following step, the Bearing Cap (119) has a lefthand
thread.
3. Using CPS3-532T Hex Socket or an adjustable Pin Wrench,
unscrew Bearing Cap (139).
4. Pull the Drive Spindle Assembly (142) out of Housing (141).
5. Remove the Retaining Ring (138). If necessary, using a bearing
puller tool, press the Rear Spindle Bearing (137) off the Drive
Spindle Assembly.
6. Tilt Spindle Housing, causing the Spring (144, 145), Square Drive
Spindle (140), and Washer (143) to slide out.
7. Note that the No-Float Models have an extra Spacer (146) inside
the Spindle (140).
