Hst/Hyd Filter Lifespan- Years, not service hours

[dodge man]

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.

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.

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!
