Grain truck oil

cumminspuller · May 23, 2019

I've got my first grain truck. 1960 Chevy C60 Viking. It is low on hydraulic oil. I've not been around these old trucks much. What type of oil is normally used in the dump system for the bed? What little bit is left in it has a red tint to it. To make sure this is tractor related. A 45 combine will be dumping corn in this bed that was planted with a 720 deere. Thanks Chris

If it has a reddish tint, it probably is ATF or it has some ATF in it. That would work or 10W engine oil or AW 32 hydraulic oil.

I have a 64 Chevy C60 that I have added regular tractor universal hydraulic oil in and it worked fine. Word of caution, if the fill tank is located under the bed use all caution to secure the bed up and use an extended hose to fill. We had to push the bed down with the front end loader and then to add security placed a heavy post across the frame scotched against the bed. Until we got the air out it would drop like a rock the first 2-3 times. Safety first always.

Use the same hydralic oil that you use in your 45 combine,and 720 tractor.

My Dad used non detergent 20 wt motor oil in those old hydraulic systems

If you have to raise the box to add oil don't fill it very full, otherwise when you lower it it will overflow.

Short version is that ANY "motor oil", automatic transmission oil, or hydraulic oil will be just fine.

If it is a typical old farm truck, likely the oil in the hoist is already a mix of several of those, whatever the P.O. had handy when it didn't lift fully!

NO 90-weight gear oil, though! (Hopefully!)

Thanks for the replies. It will go up on its own at the moment but only about half way. I will probably just add a little oil and try and keep doing that until it is working like it should so I don't over fill the tank. It is under the bed.

And as mentioned, if you do have to raise the box be sure to block it up securely with wood posts so it doesn't accidentally drop and kill you!
A good practice is after you fill it, leave the cap off the first time you let it back down. If you've overfilled it, it will overflow, which is OK. If you overfill it and let it down with the cap on it could blow the seals out of your hoist.
