Original engine lube oil was straight SAE30 with recommendation of SAE40 over 90 deg. F.
Transmission, bevel gear, steering clutches was SAE30 now would be TDTO (T0-4) SAE30 spec.
Finals were SAE50 now would be TDTO (TO-4) SAE50 spec.
Do not use engine oils in Transmission Drive Train applications.
