Preventive Maintenance
❑
To meet various shipping regulations, oil is drained from the gearbox reservoir
prior to shipping from the factory. At installation and before operating the first
time, oil must be added to the appropriate level.
Note: Hale recommends using an SAE EP-90, 80W90 Lubricant or “RoadRanger”
Full Synthetic SAE 50 Transmission Lubricant, manufactured by the Eaton
®
Corpora-
tion, or equivalent.
1. For gearbox capacity - see heading “Appendix C1: Lube and Sealant Spec-
ifications” on page 133.
2. Remove the gearbox oil fill plug,
and check the level of the oil in the
gearbox. (See Figure 4-1: “Typical
Drain, Fill and Level Plugs.”)
Have clean disposable shop rags
and oil dry handy and a suitable
container to collect the fluid.
3. The oil level should be up to the
bottom of the oil drain port hole.
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 contami-
nation.
Note: If water leak / contamination is
suspected, see heading “Troubleshoot-
ing” on page 67.
5. Either of these conditions indicates maintenance is required on the unit.
See Section 6 “Repair” on page 75.
