non-kubota filters

[art]

Going back over the past 35 years in the repair buisness on cars initially then to aircraft and then just a hobby with cars and a life of tractors this is what I've learned right or wrong with your beliefs. I also know that many of you will never run your equipment to full oil changes nor work it like some of my customers might. I do have customers that are no different than you as far as use and manitance. Price is not a issue here just quality. Wix, Napa has had more filters that will void a warrantee if used than anyother company I know; most recent the 5.9liter cummins/case engine oil filters. Filters are spec'ed for the engine by the manufacturer. Some have higher and lower bypass modes some use denser filter paper and some don't use as good of paper. There are many that the folds in the paper are very inconsisitant causing high oil travel in spot areas and other areas that filter no oil. Many of the better filters and again as to the design as to location of mounting have anti-drain back valves built into them. My favorite after-market filter is fleet guard as I believe they currently build more manufacturer's filter than anyone. That still doesn't mean thay can build to the manufacturers specs to market under there name. Case-IH is just starting a 10,000 hour warrantee on engine and drive line for ten years on there tractors! Yes they can say you have to run there oil and there filters if you want that warrantee. It's very hard for you folks sitting on the edge of this industry to know what does really make things tick, many dealers sit in the middle of it and we still make mistakes. After-market is after-market period, it just isn't the same.

Art,

Thanks for taking the time to post your view. I have some Kubota training tapes, one of which is "Air Elements, by Donaldson". Donaldson is the Kubota air filter supplier and claims 90% of the commercial "off road" market.
The tape illuminates the difficulty associated with filter design for three cylinder diesel engines. I don't think I will be looking for after market air filters anytime soon.

Do you know if Donaldson markets oil and hydraulic filters for Kubota's or who does?

I looked over their website but didn't find anything.

Twinkle toes I do believe that it still is Donaldson who is making there filters. It just seems strange we send out filters to many different areas of the country and for some one to spend ten too twenty thousand dollars for a piece of equipment and then to look to save a couple of dollars on the quality of oil and filters the life blood of that machine baffles me!

Art,
What baffles me is that you never get the same Kubota filter twice in a row from a dealer!!! Why???? Also, why are different dealers pushing different filter part numbers for the same applicaton? I know the difference between the (o) designated filters which are Japanese and the (e) filters which are the economy filters manufactured in the USA; so I can explain that difference, but I am seeing all the variations with the (e) filters. It is so bad, that I think the whole Kubota filter push is a gimmick.

I am real skeptical about all these different part numbers for the same application. If it is so important to buy Kubota, then why isn't their more consistency with the parts numbers. I can not and will not believe that all those different filter part numbers were designed for my applicaton!!!!! It sounds like substitution or close enough to me!!!!!

Art, I bought that new ZD21 the other day from ED. You guys are all right! However, I think you are a little high on that trade-in of my 54" mower deck!

Thanks...
Jon S.

The Kubota (presumably) filter that came on my L35 was different then the "Kubota" ones I purchased the same time. No part number on the one on the tractor, different color (no biggie), at least the sealing design was different.

I don't paying for a higher quality product, it does make sense most of the time. You just hate to think you're being played with by the marketing types.

I would think it would be a definite no no to use some engine oil filter (even if it screws on) to replace the hydraulic. Seems I read somewhere that the filtering requirements are much more severe on the hydraulic system. (Not to mention the problems if there is full pressure in the filter /w3tcompact/icons/frown.gif

Jon, the difference in the O and E is the is the O is original equipment and the E is for economy. I'll keep it that most dealers want to be what there customers want, a place that is not taking advantage of them. To offer the E filters helps keep the price down for the customer. We do stock some of the E's but not all. On the other side of the questions here Kubota has changed some part numbers of there filters and it might be that the dealer is still changing from the old to the new stock. It is hard to tell the efficiency of a filter by looking at it. You can cut them apart to take a closer look, we do have some already cut open and what you find is interesting. To say that the manufactuer's filter are perfect I can't say that either. We have a filter cut open here that if the filter bypass could open that it was sealed with a cork gasket! that would be good going thru the engine. While playing with one of our tractor pullers we started out with 350hp on the dyno and after changing the fuel filter we lost 200hp. Ten minutes later we were back up to where we were.

Just read your note about WIX filters for Kubotas.I have a T1760 riding mower w/48" blade and a Kawasaki
2 cyl. engine. Since its not a big item I can't find any crossovers here. Just in case you have something I would like any prices you have in air & oil filters.
Thanks

What is the problem wth Fram filters. I have been using them for years with no problem.

I agree with Art. In the motorsports industry I have learned that even products with the same brand name can be manufactured to different tolerances. For example, you can order a Dunlop tire from Parts Unlimited much cheaper than the same Dunlop model tire from Yamaha. This is because Yamaha specifies a tighter tolerance on their tires. I have seen up to 5hp difference between stock and aftermarket air filters on dyno runs on a banshee (in favor of the stock filter). I have noticed also that Fram uses one filter for three different models of motorcycle. Those three models each use a different filter from Yamaha.
I really rubs me the wrong way when I hear people say "they are all the same because they are all made by the same manufacturer". Yes, the same company may be producing several different brand names of filters, but they are not the same quality.
