850 Hydraulic Filter Installation?

Pretty much done restoring my 850. When I had lift cover off last month, I saw in the Manual that there was an optional dealer installed kit for a filter for the hydraulic system. Although not a problem thus far, I was wondering if anyone has a plan or blueprint for installing a screw on filter for my hydraulic system. I have a filter on my engine oil, front end loader, and even my power steering. I would like to be able to avoid problems with water infiltration, etc., to prevent future problems with tubes breaking from freezing water in the system, or scoring of my lift piston, etc. I am sure this has been addressed by members before, but nothing I have seen. Thanks all, Larry.

t got by for 60 years & now you worry ???

The chance of finding an OEM filter package new or used is approximately zero.

Many things can be done with enough money and/or time but this is one of those things that is not cost effective.

I doubt that you will be able to filter water out because the pump intake doesn't draw from near enough to the bottom. Water runs out the bottom pretty easily when you loosen the plug, especially if you are using plain hydraulic oil instead of UTF.

Yea, I figured it would be difficult. My boat filter system removes water from my fuel, so I thought there might be a system for removing water from hydraulic fluid before it creates a froth. And yes, I worry about my 60 year old tractor. I have a nice Mercedes sports car, and the car sits outside on the driveway while my 60 year old tractor lives in the one car garage. I bet I'm not alone.
Thanks all, Larry.

Larry, I have a pretty much restored Datsun roadster that almost always goes inside at night, while the newer cars and truck stay out. A week ago due to logistics in the shop it stayed out but with a large blanket over it. The old tractors very rarely get dew on them.


This was a week and a half ago.

ovely car AND background!

I would also like to see a diagram/ intructions for adding a filter to my 850- the loader will be easy enough, but where and how to put one in the tractor hydraulic system would be great

If you have the I&T FO20 manual, paragraph 324 and figure FO272 explain and illustrate the optional Ford hydraulic filter. A simple system, but one that would be difficult to duplicate.

"especially if you are using plain hydraulic oil instead of UTF."

Interesting comment. Care to share why?

Bingo.

Easy enough if one has the factory kit.

Not so easy otherwise.

That said, most of these hydraulic systems lasted 50+ years without major issues so long as the oil was changed at least occassionally.

Sure, UTF, due to the additives, tends to absorb the moisture, and hold it in suspension like a milk shake, while plain old hydraulic oil lets the moisture easily separate out, so it is on the bottom where it can be drained out by simply loosening the plug.

That setup looks similar to what is on my 532, maybe incorporated later as stock? Anyway, has anyone done this from scratch, and where is a good place to plumb it in where fluid under pressure can be diverted to a filter and back into the system? Mine has a single remote valve assembly

Firstly, I never knew that about Hydraulic fluid not emulsifying any contained water, versus other fluids available. Secondly, it looks like no one has tried to duplicate the hydraulic fluid filter as shown in the manual, and I am not inventive enough to experiment on one for my tractor, so I will just have to do the right thing and replace fluid each year. When I did the rebuild this summer, there was not too much gunk or any metal shavings, so the issue for me is really only water, which should not build up too bad as I keep it garaged, and when I do use it, I use it for a long enough period of time that water should burn off. I did the rebuild about 2 weeks ago, and my carry all with 400 pounds of gravel in it is STILL where I left it in the raised position, so I guess the new piston and o-ring/washer project was the right thing to do. Thanks all for the help, Larry.r
