Okay. Now this is what the Sauer Sunstrand Service Manual BLN-9646. Rev E August 1992 says about what is recommended for the 15U Series pumps. SECTION 3 Fluid Recommendations. Page 10
CHARACTERISTICS should include: Viscosity. Oxidation, Shear Stability, Thermal Stability, Low Temperature Fluidity, Anti-Foam, Water Compatibility, Rust Inhibition, Anti-Wear Properties, Filtration Limitations.
Following Types used Successfully in the hydrostatic transmission in order from the book.
(1) Anti-wear hydraulic oil
(2) automatic transmission fluid - Type "F"
(3) hydraulic transmission fluid (type used by the Agricultural industry for combined transmission, hydraulic and wet brake systems)
(4) For a required fire resistant fluid... Pydraul 312 is satisfactory.
It further states that most of the above mentioned fluid types have acceptable viscosity charastics in the 0 degree to 200 degree F operating range. Selected fluids should provide a minimun viscosity of 47 SUS @ 210 degrees F and 6000 SUS maximum measured viscosity at the lowest expected startup temperature.
