I know this has been covered a number of times..
Have a 1968 990 selectamatic..
I understand that you use 10w-30 in engine, and tranny?
Is that correct? Now for the power steering what type?
Thanks I have searched the forum with no success, but wanted to make sure..

To the best of my knowledge there is no such thing as 80-90W hydraulic oil.
Hydraulic oil usually runs several dollars less per 5 gallon bucket than diesel grade motor oil.

Forgot to mention, the loader has been working fine with the 30w oil. But I can see where this would create a problem if you had any implements that did require the 80-90w Hyd oil, and when connecting them into the system. I would probably try to find a separate pump and run off PTO, or perhaps an electric clutch type, and have it run off belts from the crank pulley, with a separate tank ect.

Just seen this. Yes, thanks, I knew I had seen somewhere that 10-30 was good enough. I have seen 20 oil at the store, don't think it was anymore than 10-30.
Thanks Again..

You don't want 80-90W in the tranny since the sump is shared with the hydraulic system. That stuff won't make it through the filter and and you'll trash your hyd pump.

IIRC it takes 7 gallons of oil for the trans/hyd. You could use 10 or 20w engine oil, but it's going to cost you.

Ok I think it was on another forum, that it was said that the tranny/hydraulic system works best with the 10w-30, as the 80-90 weight is to thick for them.
Yes I assume Rotella 10w-40 would be better than any for the engine..

I do have the owners manual for the 990, but think it was for the later model 990

They left the factory with 20W20 oil in the transmission and engine, Good luck finding any. Oils have progressed a long way since 1970. Any 15W40 diesel oil now will be better than the very best from 1970(engine).

As for the transmission... they are not picky, any clean oil of appropriate weight should be fine. I have used motor oil, it worked fine, Hytran does too.

No. You want 10-30 or 10-40 diesel engine oil in the engine. You want hydraulic/transmission fluid in the tranny/hyd system, not 10-30. I use ATF in th power steering but standard power steering fluid (about 10wt) works.

Get the operators manual, it lays all this out. This link should get you to an online version of the manual. https://docs.google.com/viewer?a=v&pid=sites&srcid=ZGVmYXVsdGRvbWFpbnxkZWVyZWJyb3dufGd4OjQwYmQ2YWU0YWNmZmI0MDQ
