Flexible Shaft Lubrication Procedure
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 casing 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…18 inches (318 457 2 mm) Apply lubricant
as above to the exposed section of core Reinstall the core,
making sure 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 procedure 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 three times for proper break-in
OTEE: N For shorter core and casing combinations, coiling
is not 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 submerged in
the mix, water and cement can infiltrate into the head unless
precautions are taken In addition 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
