Hale MBP Booster - Manual (Page 47)

❑ Preventive Maintenance
46 Silencer Series Booster Pump, p/n: 029-0020-83-0
Incorrect oil types or amounts of oil result in unnecessary loss of power and
high oil temperature. Change the oil every 12 months, depending on pump
usage. All lubricants must meet service rating API GL-5 requirements.
(See Figure 4-2: “Gearbox Capacity / Recommended Lubricants,” on page
45.)
Note: Hale recommends using an SAE EP-90, 80W90 Lubricant or
“RoadRanger” Full Synthetic SAE 50 Transmission Lubricant, manufactured by
the Eaton ® Corporation, or equivalent.
1. Remove the gearbox oil fill plug, and
check the level of the oil in the gearbox.
(See Figure 4-3: “Typical Drain, Fill and
Level Plugs.”)
2. The oil level should be up to the bottom
of the plug hole.
3. If the oil appears white or “milky,” a
water leak is indicated. Remove the
drain plug and drain the oil into a suit-
able container. Examine the oil for
metal flakes or other contamination.
4. Either of these conditions indicates
maintenance is required on the unit.
Drive Line and Flange Bolts
Check all drive line and flange bolts to ensure:
1. No bolts are missing.
2. All bolts are tight. Use a torque wrench to torque bolts to the drive train
manufacturer's recommended specifications.
Priming System Test (Dry Vacuum Test)
(Refer to NFPA 1901 or NFPA 1911)
1. Close all valves and drains. Cap all suction openings and the outlet of the
suction side relief valve (if equipped).
