LUBRICANT SPECIFICATIONS
All Traditional Crane Models
(Replaces Bulletin 152)
General
The Lubrication Guide supplied with your crane may not contain up-to-date
lubricant specifications.
You must use lubricants that meet the specifications given in this bulletin.
Approved lubricants for arctic operation are given in Bulletin 18-2.
Grease
Use an extreme pressure, heavy duty, water repellent grease that meets
MIL-G-10924-B Spec. (or later). The grease must be fluid enough to be
applied by a grease gun and to flow through grease lines at the expected
ambient temperature.
EP #2 grease is used for factory fill unless otherwise specified by crane owner.
Follow the manufacturer’s recommendations or the instructions in automatic
lube system folio for the approved grease to be used in “automatic lube
systems.”
Open Gear Oil
Open gears not enclosed in an oil tight case (such as ring gear) must be
lubricated with a thick oil that has the following characteristics:
• Resists being thrown off by turning gears.
• Resists being washed off by water.
• Resists thinning out and dripping off at hottest operating temperature.
• Resists becoming so stiff that it chips or peels off at coldest operating
temperature.
This type oil requires heating or thinning for proper application to gear teeth.
Apply a light film of oil to each gear tooth. Do not rely on gear rotation to
distribute oil.
CAUTION
COMPONENT FAILURES!
Using inadequate lubricants can result In
component failures. Warranty claims may be denied if you use lubricants
that do not meet specifications given in this bulletin.
Refer to Lubrication Guide in your Service Manual for lubrication intervals.
