  • Gear, transmission, hydraulic oil change?!?
  • I have a headache from reading a lot of stuff stored in the archives! I DO NOT want to start a controversy again. So, here goes......1952 Ford 8N. I had the pump refurbished five years ago and new fluid added. I have used the tractor regularly since then...and the lift. When it was first done the hydraulics would hold an implement up for a very long time. Now, five years later, the implements will drop over a period of time shorter than at first. I am wondering if I should drain and replace the fluid? Fluid appears clear on the dipstick.
    So, I live in a climate which gets cold in winter but I seldom use the tractor in winter. After all my reading....gasp.....I am thinking to buy five gallons of 75W90 or 80W90 gear oil. I was considering using synthetic grade oil but once I did the math I gave up on that idea! Thoughts?
    I do most of my work in spring...summer...fall seasons. Lifting very heavy discs, bush-hog and cultivator. David

  • Most leakdowns are caused by the upper Ram Cylinder leakdowns.This can be observed by removing the right side (dip stick) cover and watching the leak while lift is in action.Installing a new type neoprene seal and leather washer to the ram piston usually stops the fast leakdowns.

    Leaks in the system are causing the lift to drift down, not the condition of the fluid. Remove the cover plate on the right and check for leaks from the ram cylinder. The only reason to replace the fluid is if it is contaminated with water.

  • Ford recommended changing the hydraulic fluid annually. About every 5 years works for me. See tips 3 & 4 as to type. New fluid probably won't help the leak down which sounds normal to me.

  • Thanks Bruce for the sage advise. Interesting that this topic is seemingly complicated. Thanks again for the 75 tips.

  • Here is what I picked up today. Is this correct. About $45.00 in US dollars. OK? Dave
