Changed my Hyd fluid. I purchased a filter from NAPA it said oil filter on the can. I asked the clerk and he said some used to say oil/hyd but now they don't and they are the same. Is there a diff between oil and hyd. filters?

No difference to the best of my knowledge. However, there may be a difference between a tractor manufacturer's filter and a cross-referenced NAPA filter. I think there was a very long discussion on the subject about 1.5 years ago. It might be interesting to search the archives. As I recall somebody went to the trouble of cutting filters in half to compare them. ....

Rick I bet that on that NAPA's shelves he has at least 5 filters that have a look alike quality. They have the same threads to be fastened on by and have the same gasket diameter and are close on the diameter of housing and the same length. Either that or they found it out and you got the cheapest unit that fits those dimensions. That does not mean the insides are the same nor meant to do the same as the manufacturer designed the original to do. ....

This discussion of hyd. filters always fascinates me. Especially when people complain about OEM prices and try to save a few bucks by using aftermarket filters. I have several Kohler engines and always use Kohler oil filters. Why do I spend the extra money? Because I don't know that the other brands have the same relief pressure as the Kohler filters. Also, an extra 3 or 5 dollars is not important when compated to a $1500 gas Kohler engine. When hydro filters are involved this concern for a few dollars is even stranger. If your system needs a 10 micron filter, how do you know that the replacement isn't a 25 micron filter? Consider the cost of the hydro system and all of the parts involved. It seems to me that the assurance of the proper filter is the best peace of mind that you can have. This is one of the reasons I have mostly lost interest in the CTB. Seems like the advice is often in the "buyer beware" category. ....

Richard I hear you loud and clear. A story that Art W reminded me of a couple of weeks ago with his "T" handle Geil skid steer (notice I did not say "Bobcat"). Had a Owantonna T handle skid steer with a severe hyd pump problem after a service. Had Owantonna people come out they suspected filter problem replaced with factory brand cross reference by Owantonna same problem. Pressure from pump plenty high so they still where puzzled. They had a engineer from Owantonna fly in, it was a new line, he spotted the problem in about 5 minutes. WRONG FILTER, right number, except for a -A or something at the end of it. Looked exactly the same. Cross reference the same. Difference was the flow on the inside...That was a easy and cheap lesson in the school of hard knocks. ....

Rick, there can be a huge difference between an oil and a hydraulic filter in spite of them looking the same. Typically you can use an oil/hydraulic for either but cannot use an oil type for a hydraulic application. The difference is not in the filter, but in the pressure that the cannister is made to withstand. ....

Richard: I think that what you said is generally the view expressed in this thread. I stick with NH filters for the same reasons you give. I also usually have them couriered to me, which runs up the price even more. I think it's unfortunate if you've lost interest in the Board, so I'll comment on the 'buyer beware' idea. I think that in forums such as this it's best to get pointed in the right direction, which I believe usually happens here. There are descriptions of personal experiences and specific information. However, I think it's best thought of a good part of a new owner's essential learning process. Ultimately, owners still should be responsible for researching and making their own decisions. The problem is that even people with definite expertise (I don't count myself among experts) really can't get a sense of what's going on from the posts alone. Anybody who definitely tells another what to do starts having some responsibility for the outcome--certainly in a moral if not a legal sense. I just don't think this type of forum provides enough information to experts to allow definite recommendations to be delivered responsibly in most cases. That might be thought of as 'let the buyer beware,' but I don't think that's such a bad thing. ....

Guys, here is a subject that I do know a lot about – Oil filtration. When you go out and purchase a filter, you must realize it’s the one item on your unit that can remove dangerous contamination from your hydraulic system. Most filters will tell you their micron rating (particle size) that they claim to remove. But an equally important rating is the Bata (Bn) rating. Bata ratio is the number of particles of the specified micron size to make it through the element and not be trapped. Example Bata 12 =50 (that means 10,000 pieces of dirt size 12 micron or greater travel in but 200 are not caught) Beta 12=400 (10,000in / only 25out) = a much better filter. Also check if the filter is rated nominal or absolute (absolute is a much rated filter - it means that it will trap dirt great than the specified micron size and not just the rated size). Glue / element media / Delta P drops and other items need to be considered when purchasing filters. Your local car guy with the 16-year-old “expert” is just a salesman and only wants to sell something. JD, Kubota, NH, or any other manufacturer wants you to use a quality product to protect your machine so that they don’t have any warranty or reliability problems so they are going to make sure that OEM replace parts are the best possible – thus they are a little more expensive. ....

Phil, many thanks for the excellent response. While I never buy anything other than OEM, I've known plenty of people who go cheap - and pay dearly afterwards. I'm frugal at times, but try not to be stupid. Your response should be tattooed on the hand of every new owner when they pickup their receipt. Good information, thanks. ....
