CHANGING THE MECHANISM FLUID
To change the Mechanism Fluid in the Impulse Mechanism,
proceed as follows:
1. Use a pointed probe to push the Spring Seat (57)
against the Retaining Sleeve Spring (56). While the
Spring is compressed, use another pointed probe or
thin blade screwdriver to remove the RetainingRing
(58). Lift the Spring Seat, Spring and Bit Retaining
Sleeve (55) off the Drive Shaft (43) and remove the Bit
Retaining Ball (54).
2. Using snap ring pliers, remove the Retaining Sleeve
Spring Stop (50) from the Drive Shaft.
3. Using copper–covered vise jaws, carefully grasp the
flats of the Mechanism Cover (52) with the output end
of the Drive Shaft downward.
4. Using an adjustable wrench, unscrew the Motor
Housing Assembly (1) from the Mechanism Cover.
This is a left–hand thread, rotate the Motor Housing
clockwise to remove it. (Refer to Dwg. TPD1292.)

5. Lift the assembled motor off the Mechanism Cover and
pull the mechanism assembly out of the Cover.
6. Using a 1.5 mm hex wrench, rotate the Torque
Adjustment Bolt (33) clockwise until the Bolt stops.
Rotate the Bolt counterclockwise until it stops in new
style Liner Housings. Do not rotate the Bolt more than
3–1/2 turns counterclockwise in old style Liner
Housings or the Bolt will fall out of the Housing.
7. Using the special Tee Wrench furnished in the Tool Kit
(Part No. 100PQ–99), remove the Oil Plug (31) and
Oil Plug Seal (32).
8. With the oil plug opening downward over a container,
rotate the Drive Shaft to purge the fluid from the
mechanism.
9. Using the syringe and fluid from the Fluid
Replacement Kit (Part No. EQ106S–K400), fill the
mechanism with the fluid furnished in the Kit. (Refer
to Dwg. TPD1265.)

MAINTENANCE SECTION

(Dwg. TPD1292)
DO NOT SUBSTITUTE ANY OTHER FLUID.
Failure to use the fluid provided could damage the
tool, increase maintenance and decrease
performance. Use only clean fluid in these tools.
10. Submerge the fill opening in the remainder of the
fluid, and using a wrench, rotate the Drive Shaft to
purge any remaining air from the system.
11. Thread the Oil Plug with the Oil Plug Seal into the
mechanism until it is snug.
12. Using a 1.5 mm hex wrench, turn the Torque
Adjustment Screw clockwise until it stops. This is the
maximum torque position.
13. Wipe the outside of the mechanism dry and clean and
remove the Oil Chamber Plug. Using the syringe,
withdraw .25 cc of fluid.
14. Install the Oil Chamber Plug and tighten it between 20
and 25 in–lb (2.3 and 2.8 Nm) torque.
15. Insert the mechanism assembly, output end leading,
into the Mechanism Cover clamped in the vise jaws.
16. Insert the hex end of the rotor shaft into the hex recess
at the rear of the Drive Shaft and thread the assembled
Motor Housing onto the Mechanism Cover. This is a
left–hand thread. Rotate the Housing
counterclockwise to tighten it.
