Maintenance
FLeXSHaFT LuBRICaTIOn (100 HOuRS)
1. Using a bench vice and wrench, remove coupler from
flexshaft as shown in Figure 7. Please note threads
are right-handed on this side of the flexshaft (drive
motor end).
2. Heat should be applied to the threads to break down
the anaerobic sealant. Applying heat will help prevent
possible damage to threads.
3. Next, using a wrench and bench vise if necessary,
remove flexible shaft from vibrator head as shown in
Please note threads are left-handed on this side of
the flexshaft (vibrator end).
4. Pull the wire core out from casing. Using a clean soft
cloth wipe the grease off as it is pulled from the casing.
Wipe clean.

5. Inspect the core for broken wires, permanent set or
other damage such as an area that indicates high wear
or having overheated. If any of these conditions exist
replace wire core.
6. Use the core to push a cleaning patch through the
casing to remove any old grease or foreign matter that
may have accumulated inside the casing.

NOTICE
DO nOT use solvents to clean casing. Applying solvents
to the core or casing may cause grease (lubricant) to
breakdown, resulting in damage to the flexshaft.
7. Thoroughly clean wire core (Figure 8) if it is being
reused. A wire brush may be required to remove
hardened residue.
Figure 8. Cleaning Wire Core
8. Apply a light amout of DuBois "TPG" lubricant (Figure 8)
or a good grade bearing grease to the entire length of
the wire core.
9. Reinstall wire core back into casing. When re-attaching
coupler and vibrator head to flexshaft, clean mating
threads with an anaerobic sealant primer. Allow primer
to dry for several minutes.
10. Also apply a ring of anaerobic sealant (Loctite™ No.
271) to the middle of the casing ferrule threads.
11. Screw the vibrator head back onto flexshaft casing.
Wait one hour before using.
12. Apply anaerobic sealant to coupler threads. Insert
coupler back into flexshaft. Tighten securely. Wait one
hour before using.
