Hst/Hyd Filter Lifespan- Years, not service hours

[toukow]

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.
