Re: TX2140 with FEL 80w Gear Oil or UTF hydraulic (Tx2160,g154,tx1500,tx1300)
I've decided against the Renew type of oil, Softens seals scares me.
I'm going with a UTF.
They are about the same viscosity as 80W and are designed for Hydraulic systems.
Here's my logic.
If you believe the primary use of your tractor fluid is a
gear oil "for hypoid gears" going 90MPH down the high way
the I suggest sticking with rated SAE, API ....80-90 GL-5 or similar.
They are perfectly good Gear oils. Any of it will work fine
and I'm sure they are all Superior to the
strait 80W fluid the OEM ( Iseki)
installed and spec in there 1980 literature.
If you believe the primary use of use of your tractors fluid is
to run your hydraulics (FEL) at reasonable lift and lower times
without excessive foaming and run the FEL at colder temps.
And never get you tractor over 10MPH.
I suggest a fluid designed for Hydraulic and Gear use in Tractors
something labled Trans/Hydraulic Fluid.
IE:Travellerｮ Universal Tractor Trans/Hydraulic Fluid
I've listed all the fluids Hydraulic, Gear. UTF available at TS
and there Viscosity (SUS @ 100 F)
Notice the UTF viscosity at 100 F is right at in the middle of 80W.
Good chart on viscosity can be found at
