Synthetic Heavy Duty Grease from Amsoil.

Synthetic Heavy-Duty EP Grease
NLGI #2 (Lithium Complex - Moly Fortified)

APPLICATIONS OR REQUIREMENTS

• GHD (#2) Cincinnati Milicron P-62 Spec.
• GHD (#2) Mack MG-C
• Also available in grade #1 (GHB)

PRODUCT DESCRIPTION
AMSOIL GHD Extreme Pressure grease is qualified against the highest grease standard, NLGI GC (wheel bearing) and LB (chassis), and is designed for heavy duty applications. This grease is composed of synthetic base oils and lithium-complex thickeners that provide the film strength, shear resistance, and mechanical stability critical to high load protection. This combination excels in high and low operating temperature ranges by providing excellent oxidation stability, high temperature dropping points, good low temperature torque values and good low temperature pumping capabilities. The GHD Grease is compounded with oxidation and corrosion inhibitors, effective oil soluble EP additives and molybdenum disulfide (moly) solid EP additives for all around protection in severe conditions.

AMSOIL's top performing lithium complex thickener system provides excellent water resistance as identified by the ASTM D-1264 water washout test. Therefore, even in wet conditions a lubricant film remains present to protect equipment against wear while the corrosion inhibitors prevent rust. AMSOIL GHD grease adheres to metal and is shear stable during severe mechanical activity. These features mean the grease does not thin during operation, but rather it maintains its consistency and stays in place to provide good lubrication.

PERFORMANCE FEATURES

• Moly Fortified for added EP protection
• Adhesive and Shear Stable - prevents squeeze out
• High dropping point (exceeds 500ºF)
• Excellent water-washout resistance
• Oxidation and corrosion inhibited

APPLICATION RECOMMENDATION
AMSOIL GH Greases in grades #1 and #2 are recommended for use in manual or automatic lubricating systems. NLGI #1 (GHB) greases have better mobility and are the preferred choice for colder applications, for automatic lubrication systems with long pumping runs, and for gear box applications (where recommended by manufacturer). NLGI #2 (GHD) is the preferred choice for medium to high ambient temperatures, sleeve type bushings, high shock loading environments, high water environments, and is the primary choice for wheel bearings.

The correct consistency grade of AMSOIL GH EP Moly Greases are recommended for use in heavy and light duty applications found in manufacturing plants, automotive applications, agricultural equipment and construction equipment. These include, but are not limited to, roller bearings, plain bearings, gears, bushings, thrust bearings, wheel bearings, chassis lubrication, universal joints, ball joints, tie-rod ends, steering knuckles, and heavily loaded pivot pins on mining and off road equipment such as power shovels, draglines, wheel and back hoe loaders, excavators and bulldozers. AMSOIL GH greases are suitable for use up to 325º F. When operating at elevated temperatures, frequent regreasing may be required.

AMSOIL GH Lithium Complex Grease is compatible with many other types of grease. However, it is recommended that when changing greases, the equipment be cleaned of the old grease when possible or flushed with a liberal amount of the GL grease while the mechanism is in operation. Closely monitor the system for any inconsistencies. Any grease compatibility questions should be referred to your AMSOIL representative or AMSOIL INC.

APPLICATION MAINTENANCE
Maintaining a clean work environment is important when equipment greasing is performed. Wipe grease fittings clean prior to injecting grease to prevent contaminant ingestion. Maintain bearing housings one-third to one-half full of grease. Do not over-grease as excessive heat buildup can result. Supplement standard grease maintenance by periodically cleaning and packing housings with fresh grease on an established maintenance schedule.

AMSOIL PRODUCT AVAILABILITY
AMSOIL GHD Grease is available in 14-oz. cartridges, 16-oz. tubs, 35-lb. pails, 120-lb. kegs and 400-lb. drums.
