Replacing Worn Shafts and Sheaths

Shafts and sheaths last longer when they are not
used at sharp angles or loops, since wear occurs at
the points of greatest friction. There is no way to
avoid ultimate wear, and under normal conditions a
flexible shaft machine may require several replace­ment shafts and sheaths during its lifetime.

To expose the inner shaft follow steps 1, 2, and 3
on the previous page.

Next, remove motor connector
with 1

″ open end or adjustable

wrench.

Motor connector has a
left hand thread and must be
turned clockwise (right)
for removal.

Loosen set screw on the flexible shaft motor
coupling and slide shaft off the motor shaft.

Installation of New Shaft

1. After removing old shaft, loosen set screw on
the new flexible shaft motor coupling and slide
coupling onto motor shaft.

2. Tighten set screw
securely onto the flat of
the motor shaft.

3. Grease shaft prior to
putting on the sheath.
(See lubrication

4. Slide motor connector back up over the shaft
and tighten to the left (counterclockwise).

5. Slide sheath over flexible shaft with plain fit­ting directed toward the motor and into the motor
connector. (Each end of the sheath has a metal
fitting. One is plain, the other fits the handpiece.)

6. Adjust the shaft as
shown at top right side
