Greetings All, What type of hyd oil should I use? Just the "standard" not the high price synthetics. I got several answers at several part houses today. Thanks,
I would just use a good quality AW32 hyd oil in the hyd tank.
I believe that the AW32 is a bit light weight for a 310c. I use something called Uni-Trac (red colored) made by a supplier here in CA. It seems more like 48 weight. Call your large scale diesel fuel supplier in town, and ask what they carry. Usually they will have a good option for a JD machine.
We own a 310D, and we use AW46 in it and everything else we own. If you are buying in 5 gallon buckets, see if there is a Costco near you. They have the cheapest price around here for AW46 and is the only weight they carry.
I have a 510 and run Chevron "tractor hydraulic fluid". Never have looked at the spec. Now I'm curious and have to go look.
