Cat FDAO oil: what type should I use in a final drive and axle?
Expert Answer
Cat FDAO is a final drive and axle oil specification, often searched as FDAO 60. If you’re comparing oils or checking what goes in a Cat final drive, the key is to match the machine’s required lubricant grade and follow the service manual for the exact application. VANROCK Drives does not sell oil; we supply brand-new OEM-specification final drive-track motors and travel motors online at vanrockdrives.com. Our drives ship fully assembled, filled with oil, ready to bolt on, with fast free shipping, duties included, no core charges or exchanges, and a Limited Lifetime Warranty.
