I have a 1958, 861, 5 spd. -- I used the back blade, all winter, to plow snow. The hydraulics worked fine. - Today I started the tractor, raised the blade, and drove the tractor 5 miles to where I plan to use it for brush hogging etc. When I lowered the blade to unhook it, the hydrauics would not raise again. Is there something that I can try, for an "easy fix" ?? -- Dick

The gear, in the pump, had stripped the spline, off from the shaft. A new gear, shaft and rebuild kit, plus labor at a local Ford/New Holland dealer cost $268.71. - Thanks to Zane, you hit the problem "on the nose." -- Dick

I would first try bleeding the pump by removing the front pipe plug with the allen head hole in it. Start the tractor and let it idle as slow as possible and when all the bubbles are gone stop the tractor and put the plug back in. You will loose about a half cup usually so put something under the pump to catch the oil.
If it won't work then you must go into the lift and take out the unloading valve and clean it up and replace the O ring with the Ford O ring made specifically for the unloading valve. The old part # was NCA 836B. Don't use a substitute or you will be sorry.
The unloading valve is covered by a plate at the front of the control valve housing just above the control valve. Their is a plug over the valve that must be pulled by inserting a bolt with fine threads into the plug and prying it out with two bars. The valve can then be pushed out with a punch of the appropriate size. Don't strike it with a hammer. The O ring will be on the unloading valve that needs to be replaced.
If you will look around on the other reference pages of the N board etc you can probably find some good views of the lift to give you some idea of what you will be looking at.
When taking the lift control housing off the tractor remove only the bolts that are around the ;outside edge of the housing and do not remove any of the bolt that are inside this circle of bolts. If you encounter a bolt that has fine threads on it put it back where you took it out. The fine bolts hold the cylinder to the cover housing.
Good luck.

See the link below for the details on my booklet on the adjustment of the hundred series and four cylinder thousand series tractors.

Zane - I took the pump off from the tractor, and the gear on the back end of the pump spun freely w/o turning the pump. By looking into the pump cavity, it appears that the gear stripped the teeth on the shaft. -- I took the pump to our local Ford/New Holland dealer. Aftermarket shaft approx $40 vs. $130 for Ford shaft, plus aftermarket kit approx $33 vs. Ford overhaul kit approx $60 - I chose aftermarket shaft & Ford kit. - They had to order the parts & said pump should be ready by end of next week. -- Thanks -- Dick

Try flipping the lever under the seat that you use to select draft control or position control. My 801 works fine in position control (horizontal) but not in draft control position (vertically straight down). I will repair mine when the weather worms at my place on the Minnesota border.
Let us know if this "quick fix" solves your problem of the moment. Mike-Iowa

Mike -- I tried to flip the control lever - no luck. ---- Zane -- I'll bleed the system, as soon as the rain stops here in N.E. Pa. Thanks to both of you, for your help and speedy reply. - Dick
