2019 Kioti CK2610HST, Ford 1700 (Gone)
I notice that the CK2610HST Kioti manual calls out replacement of the air filter yearly (definitely over-kill for me, given WA), but nothing about the hydraulic and HST filters based on years. It calls for the replacement of these filters at 50 and 200 service hours. I will take a number of years to get to 200 hours, like 6-10 years or more, which is my question.

I'm using the OEM filters and just replaced them for the 50-hour service. I'm going to guess they are not using synthetic media in their construction, but do not know this for sure.

Q: Do other tractor manufacturers have recommendations as to replace the hydraulic (or HST) filter every X years? I would assume this would be very conservative, but would offer some guidance.

Thanks for any input. Toukow

Not that I know of. Why replace a filter that is still good?

As you are aware, all tractors specify filter changes in hours of use. And most of these filters are made of paper elements, which do break down over the years. My own comfort factor is to change the filters on the recommended hours or every 5 years. Which ever comes first. Hydraulic fluids i stick to hours due to costs, and top up when its needed. If you are doing only 10 hours a year on the tractor, you need to choose a filter change plan your comfortable with.

How is your diesel fuel doing during this long term storage? No water condensation inside the fuel tank?

In addition to moisture in the fuel potentially growing algae (get an additive) you may get moisture contamination in your hydraulic fluid. That could necessitate a fluid change before the recommended hours.

Follow the manual. Manufactures don't make this stuff up!

To your point about filter media breakdown, I originally was researching engine oil filters for several street bikes I own that get very little yearly mileage. I figured the oil was good as long as periodically brought up to temperature, but wondered about filter life. Research at Bob Is The Oil Guy and elsewhere turned up the horror stories of filter media disintegration, usually with little history of the filter. I realize engine oil has different issues due to heat cycling and contaminants, but wondered about these filters. I could find zero test data on engine filter lifespan, but those filters are relatively cheap- these are not. I think your five years seems a reasonable timeline.

As to the fuel, I use a couple of Power Service products for water and algae control. I keep the tank full, tractor is garage stored, and temperatures here (WA state) vary much less than in many areas of the country.

Thanks for responding, Toukow

I go by hours, but for me that means the longest filter interval is about 4 years. Pretty sure I would not go out to 10 years, but I have no facts to support that opinion.

When it comes to the somewhat universal recommendation to replace outer and inner air filters annually and ridiculously short recommendations for replacing belts and hoses I say they DO make stuff up.
It helps a lot to be smarter than the book you are reading.

You might be surprised. I'm at a little over 300 in about two years and it sits for days or weeks at a time. If I were using it more (like mowing instead of my riders), I could see being at 500 by now.

I agree RickB: Sometimes it really does help to be smarter than the book you read. I have read equipment operator manuals, that are just so poorly written and full of typographical errors, you can't always trust the manual. Parts photos taken from wrong tractor. Specs taken from wrong tractor. I did see a tractor manual listing oil changes at every 1000 hour intervals, instead of 100 hrs.

I have also seen where the very same chapters in a tractor operator manual are copied, including the spelling errors, and then used in every manual in the tractor lineup. Some of the really old Kioti tractor manuals in the early 2001 to 2003 were like that.

It’s not just the filter. What about the hydraulic fluid? How many years is it good for? I don’t know the answer but at some point in time I would dump it along with the filter.

You're right. At least when the oil starts to turn into a coffee-and-cream-brown, it's time to change it, including filter.

The manual suggests the following be replaced every two years- radiator hose and clamp, power steering hose and oil line, fuel line, intake air line. I doubt that would cost very much. :) So I agree, they do make some things up.

Valid point and I'm sure the amount of time will vary significantly for each user. My only other tractor 1979 Ford 1700 only had a screen filter and suffered a lot of issues due to being stored outside with large temperature swings. Given spin on filters on the Kioti and stored indoors, I hope the higher level of filtration will help. I just changed to Mobil 424 at 50 hours (I know, not required) and hope to get a lot of years out it given this tractor is babied compared to most. Time will tell.

Thanks for the comments, Toukow

After the first Winter I replaced the CK2610 hydraulic oil with Kubota SUDT2 and never looked back, best money spent on a mod for cold weather use.

Also Donaldson makes the air filters and they are available cheaper from other vendors.

All my diesels have water entrapment/drain capabilities. Just this year I decided to change the fuel filters on all my tractors. The oldest filter was on the 6530...built in 2007, I thought changing the fuel filter at 50 hrs was rediculous so I left it. Last spring, 2020 I changed it and found no water when I opened the drain petcock on the filter container. Dissecting the filter I did find where it had kept my fuel clean...I think they run around 5 microns of filtration whereas full flow oil run around 20. The filter media, probably cellulose was fully intact.

On the Fram name bashing thing, I had a 2 year old PH8 oil filter I removed during an oil change....2 years due to low hours and oil was barely dirty, and found the interior fully paper including the end caps which were still rigid and glued to the filter media. I had to rip at the glue to get it to release and I had to tear the paper after much effort in trying to get the seal to rupture. The converse was other brands of filters I also dissected in this experiment, all name brand, and found metal end caps.......that were not permanently attached to the media as was the Fram!!!!!!! The meda on all the filters showed no sign of deterioration......and the comparison oil filters I dug out of my used filter drum had been exposed to oil for who knows how long after having been removed from an operational engine for who knows how long operating.

That's good fuel and engine oil filter news!
At 10-15 hours per year, and my age (80 in 2 wks.), I also now know that I ain't changin no stinkin SUDT2 hydraulic oil or filters ever again!
