Preventive Maintenance
• Correct problems as soon as they are discovered.
• Inspect equipment frequently following changes in
product formulation, processing conditions or CIP
regimen.
• Always note and report any abnormal or unusual
conditions.
• Follow a regular preventive maintenance schedule.
Many factors determine the interval required for
scheduled servicing. The severity of the application
and the time between scheduled shutdowns are two of
the most significant.
When new units are first put into service, they should be
disassembled after each production run and inspected for
any obvious wear patterns. These initial inspections will
establish a process history, as well as provide a basis for
establishing a preventive maintenance schedule.
Inspections should focus primarily on tube, shaft, blade
and seal components. During normal production runs, any
abnormal conditions such as unusual noise, leakage or
vibration should be noted and corrective action taken.
Mutator Shaft Bearing
The Votator II has only one serviceable ball bearing
assembly, located in the Opposite Drive End Head of the
unit. Lubrication of this bearing while in service is done
through the use of the grease fitting located on the
Opposite Drive End Head.
Install bearing with lubrication ring in line with grease
fitting.
Use a suitable NLGI grade-2 bearing grease for the shaft
bearing. Do not over lubricate. Excessively packed
bearings will over heat and fail prematurely.
Frequency of lubrication is dependant on the environment;
daily if it is in contact with water or steam, otherwise
weekly lubrication usually is sufficient.
WARNING: Never immerse the Front Mutator
Shaft Bearing in cleaning solution or subject to
steam. Clean bearing with a dry cloth and lubricate.
Inspection of bearing should be ongoing. If looseness is
detected, replace bearing immediately. Worn out bearings
cause shaft misalignment that will cause mechanical seals
and gearbox to wear out prematurely.
Extra Heavy Duty Votator II Shaft Bearing
The shaft bearing on the Extra Heavy Duty Votator II
located in the opposite drive end head is a sealed bearing
and does not require lubrication.
Shafts
All shaft surfaces, especially in seal and bearing areas,
should be kept smooth and clean. Special care should be
taken while cleaning and maintaining seals and bearings to
assure that these areas of the shaft are not scratched or
damaged.
Shaft porosity can be detected by making an adaptor for
the threaded end of the shaft and pressurizing it with air.
Pinholes will be detected as air bubbles by submersing the
shaft in a water bath. Leaky shafts can be repaired at
WCB.
Bent or imbalanced shafts will cause premature bearing,
seal and blade wear and may damage tube walls. Shafts
should be checked for straightness and balance annually.
Gear Drive
Manufacturer recommendations should be followed for
gear oil replacement. When draining oil, examine closely
for foreign matter or debris, flushing or gear replacement
may be required.
Use Lubricant FMO-1100-AW on the Nord gearbox. A
suitable equivalent is 90 weight food grade gear lube.
The fill capacity for an empty gearbox is 5.71 quarts.
Blades
Blades that have developed a heel greater than WCB
specifications should be sharpened per instructions in this
manual. Blades worn beyond the minimum sharpening
dimensions should be replaced. Worn blades reduce heat
transfer, result in poor performance and may damage
product tubes. See “Scraper Blade Maintenance” on
page 44.
