- CHANGING

THE MECHANISM

FLUID -

To change the Mechanism Fluid in the Impulse Mechanism,

proceed as follows:

Use a pointed probe to push the Spring Seat (58)

against the Retaining Sleeve Spring (57). While the

Spring is compressed, use another pointed probe or

thin blade screwdriver to remove the Retaining Ring

(59). Lift the Spring Seat, Spring and Bit Retaining

Sleeve (56) off the Drive Shaft (44) and remove the Bit

Retaining Ball (55).

Using snap ring pliers, remove the Retaining Sleeve

Spring Stop (51) from the Drive Shaft.

Remove the Rubber Housing Boot (60).

Using copper-covered vise jaws, carefully grasp the

flats of the Mechanism Cover (53) with the output end

of the Drive Shaft downward.

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. TPD1264.

CLOCKWISE

TO LOOSEN

(Dwg. TPD1264)

Lift the assembled motor off the Mechanism Cover and

pull the mechanism assembly out of the Cover.

Using a 1.5 mm hex wrench, rotate the Torque

Adjustment Screw (34) clockwise until the Screw

stops. Rotate the Screw counterclockwise until it stops

in new style Liner Housings. Do not rotate the Screw

more than 3-1/2

turns

counterclockwise in old style

Liner Housings or the Screw will fall out of the

Housing.

Using the special Tee Wrench furnished in the Tool Kit

(Part No. 100PQ-99), remove the Oil Plug (32) and

Oil Plug Seal (33).

With the oil plug opening downward over a container,

rotate the Drive Shaft to purge the fluid from the

mechanism.

Using the syringe and fluid from the Fluid

Replacement Kit (Part No. EQ106S-K4OO), fill the

mechanism with the fluid furnished in the Kit. Refer to

Dwg. TPD1265.

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.

(Dwg. TPD1265)

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.

Thread the Oil Plug with the Oil Plug Seal into the

mechanism until it is snug.

Using a 1.5 mm hex wrench, turn the Torque

Adjustment Screw clockwise until it stops. This is the

maximum torque position.

Wipe the outside of the mechanism dry and clean and

remove the Oil Chamber Plug. Using the syringe,

withdraw .25 cc of fluid.

Install the Oil Chamber Plug and tighten it between 20

and 25 in-lb (2.3 and 2.8 Nm) torque.

Insert the mechanism assembly, output end leading,

into the Mechanism Cover clamped in the vise jaws.

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. Refer to Dwg.

TPD1266.
