oc-12 no hydraulics fluid rcomendation

[Jess]

i have a 76 spryte with an oc-12, the hydraulics have their own tank separate from the differential.
i was wondering what everyone is running, i would like to run Agco brand permatran oil because i run it in all my tractors and the one tractor has wet brakes so in my mind it should be fine but just looking to see what more experienced minds have to say and just see what people have ran whether good or bad
thanks!

Did you find out what is the correct oil to use in the OC-12 rear end? I don't see and replies. Let me know. I was thinking of using tractor r/o oil?

[Jess]

ya i spoke with nancy at spryte improvement out of idaho and was told i should run caterpiller to-4 oil 30 wt since i dont have hydraulics tyed into the rear end

There are several companies that make the TO-4

Here is one

Lucas also makes it

[meanjean]

Is it synthetic oil? Also, do I use the same oil in the drop boxes? Or gear oil?

[Jess]

on mine the drop boxes share the same fluid

[meanjean]

My machine also shares the fluid from center, to side/side. I replaced it last week. What did you use for oil?

[Jess]

napa brand to-4 30wt oil

I've been running power shift to-4 amzoil in the little bombie I have behind my house it seems to be a lot more responsive since I changed the fluid
