hydraulic oil

Allnightshifter2 · Jul 19, 2009

I'm working for a guy with a 1066, he is running straight hydraulic oil #46 in place of hy tran any insights on what damage this will do. Gears are making a knocking sound. I use hy tran in all my farmalls so I never had any experience running straight hydraulic oil. Thanks for any help.

Hytran, Hyguard, and all other "tractor fluid" is designed for power steering, transmissions, and hydraulics as well as clutches and brakes. Basically the ideal fluid. Regular hydraulic oil is just that, hydraulic oil. Only applications designed for it will last. Usually, pumps, cylinders, and hyd motors use straight hydraulic oil. These items do not need friction modifiers, water absorbtion qualities, and multiple component protection. The bearings and such in a xmission designed for tractor fluid will wear much quicker with pure hydrauic oil only.

I'd drain the oil immediatly and replace with the proper tractor fluid. One doesn't need to buy the $85 a bucket hytran. I use a localy packaged off-brand that I pick up at a Bumper-To-Bumper parts house for $30/5 gal after taxes!

The money he thinks he is saving by running cheap hydrauic oil will come back as a VERY EXPENSIVE repair bill.

Thanks for the info. I also use the napa brand hytran in my
1066, my 706 still has ih hytran but next change is going to
napa brand also. I think he or his helper just picked up the
wrong oil so I wanted some elses opinion since I wasn"t sure
what damage it would do. John k

I'm sorry, I just don't buy that regular hydraulic oil will cause problems like that. Gears and bearings only care if the fluid is wet and slippery. Last I checked hydraulic oil was just as wet and slippery as any other oil of the same viscosity.

The additives are there to preserve the oil so it lasts longer. Gears and bearings cannot possibly detect these additives, and don't care if they are there. As long as the oil isn't too thin or too thick, and is really OIL, it will lubricate the gears just as well as Hytran.

The oil part of the oil does the lubricating. It's called hydraulic OIL, not hydraulic panther urine, or hydraulic turpentine.

Your employer's 1066 has transmission problems, plain and simple. Changing the oil now, even on the off chance that it did cause any damage (it did NOT), is a waste of time and money. It's too late. Damage is done. Tractors do not magically "heal" by using a magic fluid.
