5.2.3 Models BL 40 to BL 75
Vibrators in this range have grease nipples fitted as standard. Recommended grease type 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. Ensure
that grease nipples are clean to prevent introducing contamination into bearings. Overgreasing
causes overheating of the bearings and must be avoided. Grease cavities should never be filled
above one third of their capacity. It is essential that periodically old grease is removed and the
bearings thoroughly cleaned and repacked with new grease.
5.3 Vibrator Overhaul
Vibrator overhaul is dependent on actual use and operating conditions. It is
recommended that the vibrator be disassembled and thoroughly cleaned every 9 - 18 months. If
the vibrator has been "re-lubricated" more than 6 times or is operating under severe conditions,
then it will be necessary to overhaul the unit more frequently. Due to the mechanical tolerances
and specific reassembly procedures involved with these vibrator repairs, it is recommended that
vibrators requiring full overhaul be shipped to Hindon Corporation. This is to ensure that factory
qualified service and O.E.M. quality replacement parts will be used.
