Spin on filter (JD 850)

[wct097]

My John Deere 850 has both a screen filter in the sump and a spin on filter inline with the hydraulic lines under the footboard. The filter on the machine when I got it (not running) was a Fram PH-8A. I've replaced it with that model a few times but continue to fight various hydraulic issues and I'm starting to wonder if the Fram oil filter is an appropriate filter for this use-case. Is there a functional difference between a proper hydraulic filter and the oil filters I've been using.

I'm prepping to replace the sump filter and in-line filter, drain, replace the hydraulic fluid, and replace the shifter boot. Want to make sure I'm not screwing something up with the Fram version.

The problem with the Fram PH-8A is, it is filtering too fine of a micron. You can try a Purolator L30001, it's taller, offering more internal surface area. This in turn allows the suction line to the pump to flow better.

Your JD850 is really a Yanmar YM2500 in JD green paint.

Now, with your machine and mine, NEVER use the wrong hydraulic fluid. ONLY Hy-Gard JDM J20C/J20D or Yanmar TF500A.
You can use a farm store brand ONLY if it's listed as 'meets' and never the words saying 'compatible' with.

So many Deere, Yanmar, Iseki, Mitsubish, , Cub Cadet, and other brands using the wrong fluids will ruin the machine. In the last decade several class action lawsuits of bad marketing and advertising of inferior fluids has caused machines to fail, needing a major overhaul.

Example of a store brand licensed to meet JDM J20C/J20D. Typical Ashland-Valvoline product.

If you used the WRONG fluid, you will need to replace the spin-on filter, clean the re-usable filter near the PTO spline output shaft in a 5-gallon bucket in diesel and a soft bristle toothbrush. Then fill the system with diesel. When the machine is cool, start it up, do not rev the engine ans slowly work the gears and work the 3-point. Flush the nasty TAR like substance out ! ELSE, your machine will be rendered useless for the salvage yard.

I think I used the tractor supply J20C equivalent. Travelers premium IIRC. Every time I change the fluid it works for a while, then ends up squealing and not lifting the bucket. The fluid looks milky and I pull the strainer and it's caked in goo that needs to be cleaned off. I *think* it is water intrusion from sitting outside.

I'm currently building a shop with a lean-to to park the tractor under and plan on doing a fluid replacement at that point (not using the tractor until then). Would it be worth running diesel through the hydraulics while I'm at it anyway? Would you work the loader at all while working the three point with this flush methodology? Is there a prescribed way to flush the lift cylinders and lines?

I agree, you’re getting water in it, you need to find out how, sometimes it’s a shifter boot. What not get a JD filter for it?

I ordered what I believe to be the correct JD filter. I'm thinking I'll just drain and replace the filters as planned then work the system and drain again and refill, and then install the JD filter. That way I effectively get a good flush without introducing anything else that could contaminate the system. Between a new shifter boot and parking under the shed roof, I feel like a full on flush with clean/fresh fluid is my best bet, even if expensive.

I may also look into replacing the soft lines under the tractor that connect to the spin on filter, and maybe even the power steering lines just to get everything fresh. I replaced all of the lines on the loader several years ago and they were in rough shape.

Leaning towards going with OEM JD fluid this time around.

TSC brand fluid was in the class action lawsuit. So yeah, you could have the fluid TAR build up in the machine to totally fail, rendering the machine useless.

The Proposed Retailer Settlement settles claims against Retailer Defendants Tractor Supply Company, Orscheln Farm and Home LLC, Rural King Administration, Inc., R.K. Family, Inc., R.K. Holdings, LLP, Mattoon Rural King Store, Inc., Waterloo Rural King Supply, Inc., Vandalia Rural King Supply, Inc., RK Distribution, LLC, Rural King Holding Co. (collectively referred to as “Rural King”), and Atwood Distributing, LP, together with each of their affiliates, divisions, subsidiaries, and assigns (collectively referred to as “Retailer Defendants”) that were asserted in a Multi-District Litigation (“MDL”) lawsuit. Plaintiffs believe that the primary claims in the MDL are against Smitty’s Supply, Inc. and CAM2 International, LLC (collectively referred to as “Manufacturer Defendants”), and those claims are proceeding in the MDL and have not been settled.
And in another class action filing, it's NAPA, Walmart, Carquest, Warren, Coastal, et/ al.

Genuine Parts Co. and Warren Oil agreed to pay $10.85 million to resolve a class action lawsuit claiming their tractor hydraulic fluid — sold under brands such as Napa and Coastal — doesn’t meet required specifications.
Warren Oil sells hydraulic fluid to protect tractor engines from rust, oxidation and other problems. Similar products are sold under NAPA, Carquest, Coastal and Lubriguard brands.


Plaintiffs in the case say they suffered from financial harm based on false advertising and damage to their equipment. Some consumers may have had to spend thousands of dollars to repair damage from faulty hydraulic fluid use.

This is the TSC Traveller Premium that says it "meets J20C requirements". No telling about the past fluids though. This tractor has been a bit of a basket case. I've replaced nearly everything of value on it over the past 7 years.
