Hello, I’m wondering if anyone could give me pointers on my Hydro 84s lack of forward power. I’ve worked through the repair manual’s diagnostic steps. The charge pressure is correct. The drive pressure in capsule A is correct, but the psi in capsule B stays at around 500psi. I’ve swapped the forward and backward check valves. The next step in the manual would be to isolate the drive control valve but I’m not sure how I would rig something up for that. I also changed the filter and put new fluid in. The old fluid was dark.

Started up our 1486 today after it sitting all winter and noticed when I put it in gear and let off of the clutch it is sluggish to move. In order to get it to move I have to hit the throttle. It moves but doesn’t feel like it is getting up to the right speed. Also with an implement hooked up the hydraulic levers will not fully raise the piece of equipment. Any ideas?

Hi folks, I decided a while ago I wanted to learn how to do a tractor restoration and earlier this year picked up a 1946 Farmall H. One of the first things I wanted to check on when we got it back to my place was the transmission and final drive, which had a bit of a whine (more pronounced in second gear, but also generally noisy when the clutch was disengaged while in neutral). I’ve gotten the cover off and drained a brown, thick crud from it and just recently took a power washer to it. Next I intend to get in here with either a citrus based cleaner or mineral spirits to really scrub things well. Although having gotten this far, I’m debating if I should just take the time to split the tractor, replace all the seals and bearings, and just start fresh. But that’s a different conversation. I’m here today to ask about these gears: you can see there’s some chips missing from these gears (the transmission gears all seem fine, for what it’s worth). I never found any metal pieces in anything I drained or cleaned up, so I’m assuming they’ve been there a while and someone else previously drained them away. But since I’m in here cleaning things up and pondering replacement parts, I’m just curious what y’all would think about them. Thanks for any pointers and expertise!

As part of a full restoration, I am rebuilding the differential on my Farmall C. For most information, including fasteners, I rely on the caseih parts catalog online. However, the differential case bolts have no info there. I have the old ones... somewhere... But can someone tell me if these were torqued to yield, deformed thread, higher grade, or anything like that? I'm ready to put this thing together and my nasty innate analysis paralysis won't let me. Thanks KWRB

Attached are some pictures of the transmission on my 1940 B project. I removed the gear shifter assembly and cover plate and shifting arms and put that in my electrolysis tub to soak. So, what's my next step? Any thoughts, ideas, suggestions etc are most welcome. (I also sprayed as much as I could of the gears, etc with diesel and PB Blaster because I know this is all going to have to come apart at some point.)
