Part 3 | Fixing Hydraulics On My Great-Grandfather's Tractor | Ford 601 Workmaster Diesel

Oh boy what a video! It was quite a lot of work getting the hydraulics fixed! There's a reason it's almost an hour long.

I started with an issue with the hydraulics in the previous video. The 3-point hitch kept sagging and would quickly correct itself and repeat this process over and over.
I pulled off the cover, cleaned out the sludge and added oil. I then added a new piston O-Ring and replaced the cam follower pin.
BEWARE! The cam follower pin can be EXTREMELY difficult to remove, it may not be as easy as some videos make it out to be!
Once I replaced these parts, I went and put the cover back on to test and see if I had fixed it. NOPE!
The hydraulics were now worse than before. It could raise the implement just fine, but once it got to its selected height, it would violently bounce up and down.
Upon inserting a borescope and researching online, it appeared to be something in one of the valves, possibly the unloading valve, check valve, or back pressure valve.

After pulling everything off again, I purchased another set of O-Rings and gaskets from Steiner, but it didn't have the correct O-Ring for the unloading valve.
I then found the right part number and purchased a proper O-Ring from eBay.

After replacing the O-Ring in the unloading valve, I reassembled everything and it works!

Kinda...

It moves down and can stay rock solid in place, not to mention it raises the implement much higher than before.
Only problem is that it shudders when raising the implement. This could be caused by air bubbles working their way into the hydraulic pump.
I'll have to bleed the system with the bleed plug on the pump, but I have not been able to do that just yet, I'll update below.

*UPDATE*
Jittering seems to have stopped after running it for a while, huge thanks to those that offered some insight on this issue!

Thanks for watching! I hope you enjoyed it and/or learned something.

This video series is a way for my family to be a part of this project.
