Metalfab 4P Series Vibrator
Operation & Maintenance Data
Introduction
The Metalfab Electric Vibratory Motor you have purchased is of special
manufacture. It has been designed and manufactured solely for use
as a vibratory motor, to ensure the best possible performance and
reliability under severe duty applications.
Installations
The mounting bolts used must be of grade 8 or 9 material. When
installing the motor, it is necessary to use locking nuts and tighten the
bolts evenly to the recommended torque ratings. Never reinstall used
fasteners, as they may fail under load. Check the bolts for security
after the first thirty minutes of operation and repeat after the second
day of operation.
It is imperative that the eccentric weights at both ends of the shaft are
adjusted identically; “mirror images of each other”. When adjusting
the eccentric weights, use the least amount of amplitude and force to
move your material. This will provide longer vibrator life. Refer to
page four for eccentric weight adjustment.
All wiring of the vibrator motor must be done in accordance with
National Electric Code standards. Refer to the diagrams or page two
for wiring the motors. Each motor is supplied with a wiring diagram
inside the terminal box.
When wiring the motor, always utilize the ground connection.
Note: Never weld on the bin or structure without first
disconnecting the motor leads. Failure to do so may
cause damage to the motor windings and bearings
by grounding through the motor.

Important Notice
Overload Protection Required!
This vibrator carries the best guarantee offered by any vibrator
manufacturer. To assure extended life, maintain the warranty and
comply with the National Electric Code, this unit must be wired with
the proper size overload protection.
On three phase units, use overload protection on all three legs at 10%
over nameplate amperage at the correct voltage.
If the vibrator cannot be operated in your application at this amperage
level, consult Metalfab or your local distributor. Do not increase the
overload protection rating. This may destroy the vibrator and will void
the warranty.
Connection Diagrams
All units have DUAL voltage in 3 phase 230/460 volt. To change from
one voltage to another, remove cover on conduit box and reconnect as
per diagram below.
To change rotation on rotor, interchange any two lead wires. This is
done either in conduit box or at the plug.

Lubrication Instructions
The ball bearings in the 4P-0.35K, 4P-0.75K and 4P-1K are prelubricated for life. All other models have two roller bearings with
grease fittings. The life of the roller bearings reach far beyond the ball
bearings, however, the roller has a larger contact area than the ball
and needs more lubricant. Therefore, they have to be re-lubricated at
certain intervals. For 1725 RPM vibrators, every 1,000 to 2,000 hours
or every month for continuous duty. The amount of lubricant should
be 2.5 to 3 grams (two pumps with standard manual grease gun.) Do
not over grease. If too much grease is applied it will leak out. By
removing the end cover you will find out if the unit has been
excessively over greased. Clean out excess grease. The same amount
is on inside of bearings on stator side. If too heavy, unit should be
taken apart and cleaned. For vibrators without grease nipple, the
outside eccentric and bearing cover have to be removed. If the
bearing has a grease seal, remove and discard it. Remove as much as
possible of the old grease and repack bearing.

Recommended Lubricant
American Oil Co., Rykon #2 EP, or Chevron BRB #2, or other
comparable lithium base lubricant with a temperature range of 300°F.
Eccentric Weight Adjustment
All Metalfab Vibratory Motors feature eccentric weights to change the
amplitude and centrifugal force. The following procedure should be
adhered to whenever the eccentric weights are adjusted.
1. Remove the eccentric weight covers on both ends of the motor.
2. Note the present eccentric weight setting.
3. Loosen the bolt holding the eccentric to the shaft.
4. Line up the desired number on the eccentric with arrow on the
shaft.
5. Tighten the weight adjustment bolt and duplicate this process on
the other side of the motor.
Note: The upper and lower eccentric weights must be set
at the same number.
WARNING: Before any adjustments, vibrator should be
electrically “LOCKED OUT”.

*HIGH FORCE SETTINGS – AS SHIPPED WITH BOTH INSIDE AND
OUTSIDE ECCENTRICS ON BOTH ENDS OF VIBRATOR.
**LOW FORCE SETTINGS – REMOVE INSIDE ECCENTRIC ON BOTH
ENDS OF VIBRATOR. REMOUNT OUTSIDE ECCENTRIC AND LINE UP
NUMBER WITH ARROW ON SHAFT.
Trouble Shooting
A. VIBRATOR DOES NOT START:
1) Short in lines
2) Burned out overload protection
3) Short in winding, check with ohmmeter
B. VIBRATOR OVERLOAD POSSIBLE CAUSES:
1) Bolts holding vibrator are loose
2) Excessive ambient heat
3) One phase open (check: a) power source; b) wiring)
4) Bad bearings
Note: Always make sure the data stamped on nameplate
corresponds to power sources.
WHEN INQUIRING ABOUT ANY VIBRATOR, ALWAYS REFER TO
THE SERIAL NUMBER STAMPED ON THE METALFAB NAMEPLATE.
