Valve Lubrication
1. On handwheel-type valves, including PM, PMD, and Transfer Valve Controls,
remove old grease and paint, use a dry lubricating spray on gears.
2. Lubricate suction threads with a light coat of grease.
Suction Check Valve Testing, Two-Stage Pumps
On two-stage pumps, remove the suction tube strainers, and reach inside the pump to
ensure that the check valves are free to swing. Also verify that no foreign matter is
caught between the valve and the seat.
Gearbox Lubrication
Incorrect oil types or amounts of oil result in unnecessary high oil temperature and
possible wear or damage. Change the oil every 12 months, depending on pump
usage. All lubricants must meet service rating API GL-5 requirements. (See Figure 5-
5: “Muscle Pump Service Chart, Part 2 of 3” on page 89.)
Note: For domestic use, Hale recommends using an SAE EP-90, 80W90 Lubricant or
“RoadRanger” Full Synthetic SAE 50 Transmission Lubricant, manufactured by the Eaton
®
Corporation, or equivalent. For International use, Hale recommends using an ISO68 lubri-
cant, or equivalent.
1. For gearbox capacity - see heading “Lube and Sealant Specifications” on page
187.
2. Remove the gearbox oil fill plug, and check the level of the oil in the gearbox. The
oil level should be up to the bottom of the oil fill plug hole. Also see Figure 5-5:
“Muscle Pump Service Chart, Part 2 of 3” on page 89.
3. Have clean disposable shop rags and oil dry handy and a suitable container to
collect the fluid.
4. If the oil appears white or “milky,” a water leak is indicated. Remove the drain plug
and drain the oil into a suitable container. Examine the oil for metal flakes or other
contamination.
Note: If water leak / contamination is suspected, see Section 5 Troubleshooting, heading 6
“Troubleshooting” on page 93.
5. Either of these conditions indicates maintenance is required to the unit. See Sec-
tion 9.1 “G Series Gearbox Maintenance” on page 149. Also see Section 9.2 “J
Series Gearbox Maintenance” on page 157.
