What oil does a Cat final drive use?

Expert Answer

For a Caterpillar final drive, the correct oil depends on the exact machine model and the drive train specification. Some Cat applications use Caterpillar’s own drive train oil, while others call for gear oil or another approved fluid, so it’s important to verify the requirement in the operator’s manual before filling. If you’re replacing the final drive itself, VANROCK Drives supplies brand-new OEM-specification final drive-track motors and travel motors online at vanrockdrives.com. Every unit ships fully assembled, filled with oil, ready to bolt on, with free express shipping, duties included, and no core charge or exchange.
