flexshaft as shown in Figure 10. Please note threads
are right-handed on this side of the flexshaft (drive
motor end).

the anaerobic sealant. Applying heat will help prevent
possible damage to threads.
6. Next, using a wrench and bench vise if necessary,
remove flexible shaft from vibrator head as shown in
Figure 10. Please note threads are left-handed on this
side of the flexshaft (vibrator end).
7. Pull the wire core out from casing. Using a clean soft
cloth, wipe the grease off as the wire core is pulled
from the casing. Wipe clean.
