Hydraulic system.

I have a case 1845 b skid steer and I want to change the fluid and hydraulic system some say use 10W30 motor oil. And others say hydraulic fluid which one do I use thank you very much

I believe those older machines used 10w30, but if I was you and wanted to be sure, I would just call my local case dealer, give them your vin and ask them what to use, I'm sure they would know for certain and get you accurate info!

another question I think maybe you should be asking or food for thought is,
WHAT fluid is in the tank NOW< as what ever that is, , maybe stick with it? as mixing fluids is never the best idea, and with these older machines, , as time passed, many owners used WHAT ever they had on hand, from gear oil, basic hydraulic fluid to 10w30 too???
if your not the original owner, this can be a unknown deal?
guess you have to look at fluid and go by maybe color/smell, or?? not sure if a sample can be sent out and tested if one wanted too?

Thank you so very much for the info I surely appreciate it! We are blessed. By others who care. Will let you know so maybe I can help others .as all the others and you have helped many others. We all are truly blessed to have each other to lean on. Thank you and all the others for helping me! on my journey of resurrecting the old skid steers from the past. With less emissions! And and ease restriction sincerely Georgia based. pinto bill

I would guess originally Case called for 10W-40 engine oil plus their pricey HTO additive. I would advise against the 10W-40 oil unless you are in a climate that never sees temperatures near or below 0 F. Case later began to specify 10W-30 engine oil which I think is a better choice in extreme cold weather, and seems not to hurt performance at all in hot weather. I have been using a premium hydraulic oil in my 1835Bs as I was tired of paying for Case's overpriced HTO. So far as I could tell, the purpose of HTO was mostly to increase the ZDDP levels of oil in the hydraulic system. I figure any modern premium hydraulic oil will have the proper additives to keep the pumps and motors in a skid steer alive and well.

We started out using 10W-40 plus HTO in the longest owned 1835B, then went to 10W-30 plus HTO, and now to premium hydraulic fluid. Never did really do a change between fluids. Only hydraulic trouble said loader had was a failure of the gear pump for the loader/bucket, and that was likely due to cavitation from the 10W-40 oil in extreme cold weather.

I am using Mobil 424 for hydraulic oil but any other brand equivalent should be fine.

I can understand your appreciation for older machinery. It may not have the creature comforts of the latest equipment but it was designed from the ground up to work, and that is what pays my bills.

I have a Case 1818 small and older. No bells or whistles. The Hyd oil used since new is 10/30 never added to it at all. Same for the small engine Onan air cooled. It is in the Upper Penninsula of MI. I use is for General purpose things and it worked out fine. Today I have a right side drive that seems to be not working. Left side works and I have no idea if it is belts pumps or who knows what. Other than that it's worth all the repairs. Got to love the older units.
