Hydraulic Oils for Trucks, Equipment and Tractors

Three anti-wear grades, AW 32, AW 46 and AW 68, serve dedicated hydraulic systems on construction and oilfield equipment, truck-mounted hydraulics, forklifts and lifts, and shop power units. Bedrock J20C, a universal tractor hydraulic and transmission fluid, serves tractors and equipment whose hydraulics, transmission and wet brakes share one sump.

Bedrock hydraulic oils are for fleets with dump bodies and liftgates to keep working, construction and oilfield operators running excavators, cranes and service units through long Gulf Coast shifts, repair shops that stock a grade for every machine they service, and farms and ranches that run tractors on a universal fluid. Every Bedrock hydraulic product ships in the 5-gallon pail and is sold through Bedrock dealers, starting with TTM Diesel at 4939 North McCarty Street in Houston. Product Data Sheets and Safety Data Sheets are available on request.

How to choose

• Fill by the grade on the reservoir decal or in the operator's manual; Bedrock AW 46 is the grade most mobile and shop hydraulic systems specify in a warm climate.
• Where the manual names ISO 32, or the maker's temperature chart moves the machine down a grade for cool-season work, use Bedrock AW 32.
• Where the manual names ISO 68 for systems that run hot or carry heavy loads for long hours, use Bedrock AW 68.
• For tractors and equipment whose hydraulics, transmission and wet brakes share one sump and whose manual names a J20C fluid, use Bedrock J20C.
• A universal tractor fluid (Bedrock J20C) and an anti-wear hydraulic oil (Bedrock AW 46) are different types; do not swap one for the other unless the equipment maker allows it.
• If the manual is missing, ask the equipment dealer for the maker's grade chart before filling; the grade depends on the pump and the temperature the machine works in, and the Bedrock dealer can help you match it to AW 32, AW 46 or AW 68.
