Go to your bulk oil disturbter and get a name brand of hyd. oil. Even big tractor any more use hydraulic fluid where the hydraulic system, transmission, differential and wet brakes are all together. That 90W gear oil is to heavy. Would take all the horses the engine has just to move it in the winter. [Reply]   [No Email]

Those transmissions are known to be noisy from the factory, the best oil to use is 80W140 or even straight 140 in a warm climate it is not too heavy. The only IH tractors that need hyd oil are the ones with a torque amplifier, and those have gear clash when shifting due to the equivalent SAE 10 wt, 20 wt or 10W30. There are still 10s of thousands of Farmall letter series tractors using gear oil -- I have 5 of those and 2 with TA's that use hydraulic fluid.   [Reply]  [No Email]
