Trans/Rear-end/Hydraulic fluid

Kevin in Iowa · Apr 11, 2011

I am getting ready to get my 830 CK Tractor back together and its time to buy fluid for the rear-end, trans,hydraulic fluid. Previously when I"ve don a change I"ve used Case fluid at about 100.00 per 5 gallon. The local NAPA store has a couple of other options. They have a "Hydraulic Fluid" called "AW-32" as well as other "AW" weights 46, 48, etc.. They also have a fluid called "Tractor Hydraulic Fluid" on the bucket it says it meets "John Deere J20C Specs" then on the back it does mention some case models that it is compatable with.. didnt see an 830 CK, but it did say C.O.M. Any thoughts as to if one of these would work? They are roughly about the same price 45.00 per 5 gallon. Thanks

Straight Hyd. Fluid won't meet the "EP" Spec. of a tranny fluid like the Trans.-Hyd. will. Use the Tranny-Hyd. fluid. I always stiffen it up a little w/ some 85W140.

Thanks... that what I was thinkning about the one that says "hydraulic fluid" sounded like only hydraulic fluid to me...

So you think the "tractor hydraulic Fluid" that meets "JDJ20C" spec (and other case models) will be safe?

Case Hytran oil should be around $60-70 for 5 gal.

I bought a 1370 Case a couple of years ago and replaced the oil with what I thought was a premium oil.

I’m currently rebuilding the entire rear end because the oil I used eat every paper fiber disc in the tractor.

The old 830CK tractors are less forgiving because they DO NOT have internal brakes and differential clutch plates like my 1370 but they still can benefit from HYTRAN.

Hytran absorbs moisture, does not contain zinc which causes corrosion thus protecting your hydraulic valve spools, rear end bearing etc…

Personally I would suggest you call a couple of Case IH dealers and see what kind of price you can get on Hytran.

If you still want to go another route then buy an oil rated for your application and don’t mix.

Labor and parts cost a lot of money these days and its worth protecting them from undue wear and corrosion

Just my opinion, I hope this helps

Ya I hear what your sayin... just called locally here.. $70.00 for a 5 gallon.. not bad.. I though it was more like 100.00 a couple of years ago.. I will probably go that route.

I have a 1966 930 CK six speed. I changed trans oil at 3000 hrs. The book called for TCH. I put in 85-140 and haven"t changed sence. I now have 8495 hrs. Should I change back to HY_Tran or refill with 85-140? I wonder if my seals would hold HY_Tran? And would it lubericate good enough that old of gears and chains?

Does that 930 still use as separate Hyd. resoivoir? It must, because I can't see how the hyd's would work w/ 85W140. If it does have a separate hyd . resoivoir, then absolutely stay w/ 85W150 in the tranny.

Yes it has separate resoivoir for hyda. The reason I changed to 80-(90)140 way back in 1972 was (being from the old school) I thought the TCH was not good enough because the tran made a lot of noise with TCH and was quiter with 85-40, and beside the 1961 930 lp I had used 80-(90)140 and the trans. is exactly the same. I have never had a speck of trouble with the trans or final drive and this oil has been in it for 5500 hrs or 29 years. So I thought I better change it this year.
