4. Replace rotor assembly in head housing. Apply Loctite® 545 adhesive/sealant or equivalent all around
the threads of the end cap. Tighten and wipe off excess Loctite® 545 adhesive/sealant.

Flexible Shaft - lubrication

When vibrators are shipped completely assembled from the factory, the shafts are lubricated and
broken-in. If separate cores and casings are shipped, they require the following lubrication and break-in
procedure. Core and casing combinations should be checked for lubricant levels at least every 50 hours.
To lubricate, lightly coat the core with grease (Wyco 514-B shaft lubricant) while inserting it into the cas-
ing. Do not over lubricate. Surplus lubricant may get past the seal in the vibrator head. Over lubrication
will also increase the amount of torque required to operate the vibrator, resulting in additional stress on
the motor and possibly early core and casing failure.
When adding lubricant on the job, after each 50 hours of operation, loosen the casing from the motor
and pull out the core about 15 to 18 inches. Apply lubricant as above to the exposed section of core.
Reinstall the core ensuring that it engages with the vibrator head. During operation the grease will travel
the full length of the casing.
A break-in procedure is required after the assembly of separately shipped core and casing. This proce-
dure involves repeatedly coiling the flex shaft from the head to the motor while the motor is running.
The coiling and uncoiling should be repeated at least 3 times to ensure proper break-in.
nOTE: For shorter core and casing combinations coiling isn't possible. Break-in for short core and casings requires bending into a
"U" shape instead of a coil.
Water is one of the greatest enemies of satisfactory performance of vibrator heads. As the head is sub-
merged in the mix, water and cement can infiltrate into the head unless precautions are taken. In addi-
tion to securely tightening the head onto the flexible shaft, the threads on the head and shaft must be
coated with Permatex ® Form-A-Gasket® No. 2. This must be done each and every time that the head is
removed and reinstalled.
