Engine oil is quoted as CD, so use a CI-4 or CJ-4. Viscosity depends on your ambient temperature. If it goes down to freezing use 10W-30, if it is slightly higher use 15W-40.
Transmission is quoted as TO-2 SAE30, so use a TO-4 SAE 30.
Hydraulics is quoted as SAE10W. You can use either 10W hydraulic oil or even a 10W TO-4 if you like.
Final Drives are quoted as LO SAE 30. You can now use TO-4 SAE 30 in that compartment also.
