I don't have the serial number because it's some farmer, but the machine is a 2004 Caterpillar 420D. Question was what to use in the transmission, front axle, and rear axle. It's not a 4-wheel steer.
It should use TDTO 30 in the trans, TDTO 30 in the front axle, and MTO 30 in the rear axle. The guy decided to use CNH HyTran in the trans, and 85-90 gear oil in the front and rear axles. Thoughts??
