I have a 1968 Ford 4000 3cyl gas. When cold, the hydraulic 3pt lift does not raise until maybe 10 minutes after the tractor has been running at mid-high range rpm. If it just sits at idle, but warm, it doesn't work until I raise the rpm's up to mid-high range for at least a couple minutes Then works fine as long as I periodically lower and raise the 3pt. If I turn off the tractor and it sits for maybe 30 minutes or more, 3pt does the same thing where it won't raise for several minutes (even though still warm). Once working, the lift has plenty of power and holds up implements fine. I thought maybe the unloading valve is sticking.
I talked to a New Holland service rep and he suggested replacing the oil with kerosene or diesel fuel, and to run it maybe 30 minutes to get it warm. Then, add fresh oil after removing the kerosene/diesel wash. I asked the service rep could that hurt the hyd pump. He said no, and added that I would not be running it for prolonged period in the diesel. Has anyone done this? For the most part, a search online hasn't shown much support in doing this.
Related to that, I asked about how much to split the tractor (no loader attached) to replace the spin-on hyd filter and maybe clean the pump screen. The NH rep said it would be 2-3 days labor at about $80 per hour. I said you don't mean 8 hrs per day, and he said yes. So I laughed and said I'd try the fuel washout first.
