Two winters ago, I got my grandfather's 841S. I spent the second half of that winter getting it as field-ready as I could (had the front end completely off and replaced, as well as many other things, most of which you can find in my past posts). This past winter, I split the tractor to replace the clutch and fix some other odds and ends. I have already been given my project for this winter: the hydraulics.
The lift arms don't work at all in draft control mode (regardless of where the control lever is, they immediately fall to a lowered position), and work "funny" in position control mode. Even though the position control lever moves freely throughout its range, the "lifting action" only occurs around the last 10-15 degrees of motion from having the lever "all the way down" to "all the way up." The lift arms also "leak down" when the tractor is running when the arms are in any position except all the way up.
That being said, the lift arms are quite strong, and work quickly. I also have a remote hydraulic valve, which works fine. So I think my pump is in good shape.
When I go to take my top cover off and delve into this beast, what should I be looking for? Are there any tips I should keep in mind? I have both the red Ford shop manual and the IT manual, but I've learned they're written for people with far more mechanical knowledge than me.
Of all the things I've worked on on this tractor, the hydraulics make me the most "nervous," simply because I feel I have the least amount of prior knowledge about how they operate when compared to the other systems I've repaired on this old gal.
I have used the knowledge I've gained on this forum to help a friend of mine bring his dad's 850 back to life, so I'm very grateful for your continued help!
