[tallboy]

Hello - simple question, I hope. Is 80w/90 oil sufficient for the hydraulic /gear oil for a 7211 or what is better?

I have these figures for a 5745:

Engine: 12 litre 15W40 diesel engine oil

You will see things like "API SG/CJ" on the oil container, that means:
API = American Petroleum Industry
SG = Spark ignition, grade "G", for gasoline engines
CJ = Compression ignition, grade "J", for diesels

Power steering: 4 litre ATF-2

All following are SAE80W90 gear oil or 15W40 STOU multifarm:
(SAE80W90 should be cheaper)
Gear box: 34 litre
Injection pump: 0.2 litre
Air cleaner: 1.3 litre
Portals: 3.8 litre
Steering box: 1.9 litre
Front differential: 3 litre
Front planetoids: 1.5 litre
===========
Total 45.7 litre

Of course, for the air cleaner you can basically use any oil of any viscosity because it is only for pulling the intake air through.
