5.0 MAINTENANCE
5.1 Routine Maintenance
Routine maintenance deals predominantly with the proper lubrication of the vibrator
bearings. The lubrication intervals and amounts vary greatly depending on the vibrator model and
are further affected by outside factors such as duty cycle, ambient temperatures and operating
environment.
5.2 Bearing Lubrication
5.2.1 Models BL 03 to BL 20, BL 24/25-8/2, 7.5/4 and 4/6
Relubrication is not applicable since these units are manufactured with prelubricated
sealed ball bearings, and as such, are lubricated for the life of the bearing.
5.2.2 Models BL 24 – BL 30 (Except BL 24/25-8/2, 7.5/4 and 4/6)
Vibrators in this model range are not typically provided with external grease nipples.
The following steps should be carried out for proper bearing relubrication.
1) Ensure vibrator has been properly disconnected from the electrical power source prior to
proceeding.
2) Remove both end covers.
3) Remove the O.B. weights from each side of the shaft extension, taking care to first remove
shaft snap rings. Also, be sure to mark the current weight setting positions prior to removal
to ensure proper centrifugal force upon reassembly.
4) Remove both bearing housings (which contain the bearing outer races). The inner races
remain on the rotor shaft.
5) Bearing rollers and cages will now be exposed. Using a clean cloth, remove as much old
grease as possible and add additional grease as necessary by lightly "smearing" into the roller
cavities.
6) The factory recommended grease for Invicta Vibrators is: EXXON - UNIREX N2 or N3.
Do not mix grease types without first checking with supplier to ensure they are compatible.
(If mixing of grease is unavoidable, use only lithium complex alternatives.) Please refer to
Table 3 (page 9) for determining relube amounts and intervals.
7) Re-assemble vibrator in reverse order of disassembly. Ensure that all fastener threads have
been coated with Loctite #242 thread locking compound and are properly re-torqued to the
values listed in Table 1 (page 3).
