Hydraulic Fluid type?

[RNeumann]

Normal motor oil has detergents in it to pick up crap & keep it suspended in the oil. Great when you change the oil once or twice a year. Not so good for long change times & systems that should be cleaner. Non detergent oils let crap fall out of suspension into the bottom of the sump. I wouldn't use motor oil on my non motor equipment. I do use non-detergent motor oil in my compressor though & would use it in a splitter or dump trailer hydraulic system.

Great point! Non detergent is the recommendation in this application and others (Komatsu etc) that use straight weight oil.

It will be interesting to see how ATF works in this application. It's the general consensus the tolerances are greater in these machines which is one of the reasons for straight weight oil. Maybe OP is a place colder than Russia which would require the low weight ATF.

I have finished installing the new hydraulic pump and have filled the system with Dextron3.
The hydraulics work great even with an outside temperature of -23c . That -9.4 F.
Thanks for all the help.
