Full synthetic formulation to improve gear and bearing life in final drives and axel, as well as allows for extended drains.
Meets the performance attributes of synthetic fluids for Caterpillar final drives and axles
Protects gears and bearings against wear in severe duty applications
Improves extreme-pressure (EP) performance when compared to TO-4 fluids
Enhanced low-temperature performance when compared to conventional CAT final drive and axle fluids
Field tested
Extends drain intervals — allows a drain interval of up to 6,000 hours for off-highway trucks final drive and rear axles compared with a 2,000-hour drain interval typically recommended for TO-4 fluids*
Not for use in compartments containing friction material unless an FD-1-type product is specified
Credentials and identification
Meets the performance attributes of Synthetic Caterpillar FD-1 lubricants
*Any drain interval extension beyond Caterpillar recommendations must be accompanied by an oil analysis program.
