Monolec® Power Fluid (7500)
Product Description
Long-Lasting Lubricant Provides Heavy-Duty Transmission Protection for Hard-Working Fleets
Even in severe field conditions, Monolec® Power Fluid (7500) ensures constant, long-lasting performance for most heavy-duty transmissions, combination transmission-hydraulic (wet brake) systems, and hydraulic systems. Its unique blend provides the proven protection of the most advanced wear, friction and oxidation inhibitors, all in one complete formula that you can count on to deliver superior wear performance, consistent friction characteristics, exceptional oxidation stability and excellent foam prevention.
Monolec® Power Fluid meets the requirements of a wide variety of manufacturers for systems used in construction, farming, manufacturing, material handling, mining, quarrying and trucking. Its versatility allows inventory consolidation, with just one lubricant for all of your transmission, axle and hydraulic protection needs.

Superior Wear Protection
Gear Wear Test Results
This Gear Wear Test (ASTM D4998) uses a modified FZG apparatus that operates at gear loadings of 284,000 psi (10th load stage), speeds of 100 rpm, and a temperature of 121°C (250°F) for 10 hours. At the end of the test, the gears are removed, weighed and visually inspected. LE’s Monolec Power Fluid (7500) exhibited a weight loss of only 35 mg, which shows its superior protection when compared to the commercial grade power fluid, which demonstrated a weight loss of 366 mg.
This test represents a close correlation with three tractor manufacturer gear wear tests: Ford, J. I. Case and International Harvester, all of which also show a weight loss of 50 mg or less as excellent performance. Because of this correlation, this Gear Wear Test was adopted as the ASTM D4998 standard test method for gear wear in tractor hydraulic fluids. The upper limit for gear weight loss in the ASTM standard is 75 mg.
Axle Wear & EP Test
In this proprietary test for axle wear and extreme pressure, LE’s patented additive combination provides clearly superior protection from the gear pitting and ridging that can reduce axle life.
Exceptional Oxidation Stability
Tendency for Frictional Problems as Oil Oxidizes
This proprietary test, using clutch material from an Allison transmission, demonstrates the ability of Monolec Power Fluid to maintain its frictional properties even when subjected to oxidation.
Excellent Foam Prevention
Foaming of lubricants is known to cause problems with pump cavitation, inefficient control response, and even oxidation. Monolec Power Fluid has been specifically formulated to minimize the formation of foam even under more turbulent conditions in severe applications.
Consistent Friction Characteristics
Frictional Properties Measured at Various Speeds
Monolec Power Fluid is formulated to maintain its friction profile under a variety of conditions to help promote smooth performance and extend equipment life.

Proprietary Additives
LE’s proprietary additives are used exclusively in LE lubricants. Monolec Power Fluid contains Monolec.
Monolec® wear-reducing additive creates a single molecular lubricating film on metal surfaces, vastly increasing oil film strength without affecting clearances. An invaluable component in LE’s engine oils, industrial oils and many of its other lubricants, Monolec allows opposing surfaces to slide by one another, greatly reducing friction, heat and wear.
