Does your tractor have a transmission oil filter magnet?

[xcgreene]

Thanks for the thread link - I'll take a look at it. Sure would be nice to not have to buy an overpriced filter from Kioti/Daedong.:thumbsup:
Isn't the EX a series not available in the US market? That could be why it's NOT included on machines sold here, and for possibly no other 'logic'. Is the part you're referring to able to be purchased for 'retrofit' on a case by case basis?
If you do find it and install it can you keep us up to date on the progress?

Thanks,

CM

You are correct, the EX series is not available in the US, but the DKse models are of the same platform, I have the workshop manual for the EX and use it for my DK and one would think they were the same tractor at first glance. But their are differences. So my hope is that the housing for my filter, has a threaded hole inside that will accept the magnet assembly like we see in that diagram. I'm also not above purchasing the housing from the EX should I not find a threaded hole in mine, as the hard pipe connections are the same. Or if the casting of the housing allows, I may drill and tap. :devil:

Seems like a lot of trouble to get a magnet at the filter: 'I may drill and tap. :devil:'. Then you may REALLY NEED a magnet!
Is the USA filtering method that inferior when it comes down to it? I would think the regular changing of the filter would remove most contaminants from the time the first factory filter is changed out, through the life of the transmission.
I've heard that for HST transmissions in general one of the most important things is to make sure the proper specs fluid is used; for instance with wet brake capabilities, and so on...

There is always a bunch of metallic (magnetic) "fuzz" on my magnet when I change the filter.

Kubota super udt is supposed to go 400 hrs with the filters at 200hr intervals.

Lots of wear items in the hydraulics. Lots of meshing gears, clutch and brake lining material.

Not an oil engineer, but I like to think the magnet helps, or at least keep all that metallic fuzz from plugging the filter up and going into bypass.

Heck, I even stick a couple strong magnets (torn out of an electric motor) around my engine oil filters on all my ewuipment

Oh its not too much trouble, I enjoy the tinkering. Having a magnet, that can be easily inspected, within this system is a good thing. Most all larger equipment with similar components utilize magnets in a similar fashion. I see it all the time in the drilling, dredging, and marine industry. I wouldn't be surprised if the DKse's lack of magnet over the EX is nothing more than Kioti USA being underfunded and unorganized as compared to Daedong Korea. Perhaps not, but I've seen enough examples in the US to convince me. Every problem I've had with both my DKse's were problems arisen from final assembly in North Carolina, or my dealership mistakes before purchase. Everything from factory Korea has been spot on, and of great quality.

After speaking with MIE yesterday about magnets in the DKse tractors, its only the drain plug magnet. They are aware of the EX's filter magnet, but are unsure of its fitment in the DKse. So, I'll be at work for the next few weeks, but when I get back I'll removed the hyd filter and have a look for a threaded hole to screw the magnet into. I suppose i could even pick up the housing from the EX, which would fit on the DKse. looks to be about $35. I guess I'd only have $100 invested in this, and would be entertaining.


I agree it is very important to use an appropriately rated fluid in the HST. I'll add that I don't think there is anything magical about Kubota, JD, New Holland/Ford, Kioti Hyd/trans fluid. I think its more important to change the oil after so many hours with properly rated oil, than what brand oil you use. Any additive packs that may be in the oil, will certainly shear away after time. Anything smaller than 11 micron (size of the DKse HST filter) will also continue to build and build within the tractor, again highlighting the importance of an oil change and a magnet.

I do realize I'm splitting hairs to some degree, But we all do when it comes down to our field. It's like watching a blockbuster movie involving your profession, You'll notice every deviation and unlikeness, tormenting you the entire movie. But to everyone else, the movie is fine, and you come across as being over analytic.

I agree. I've done the same with magnets on oil filters. As a footnote, I was mowing the edge of the field one day, and as the brush was sliding down the side of my old John Deere 2510, i noticed some branches coming close to the engine oil filter which I had a small neodymium magnet on top of. I then had a moderately disturbing epiphany, make sure that magnet does not get removed/brushed off from the filter. All of the metal on the inside will fall off in a slug of metal powder. I started placing the magnet in a more strategic place on the filter, away from any potential obstacles, or friends pulling it off out of curiosity.

So I ordered that magnet Assembly part #T4260-38841 from Messicks. Came to $35.32 after shipping. Not only is this for the EX tractors which are very similar to the DKse series, but also the Cub cadet tractors 8354, 8404, and 8454, which look to be the same platform as the old DK tractors.

Reguardless, the point of this was to see if the DKse tractors could use this same magnet assembly, which is factory spec for the EX, foreign kioti.


After removing my hydraulic filter I found an 8.5mm hole that is 16mm deep already drilled, but without threads. The magnet assembly threads are M10x1.25, so I used that size starter tap. Went very smoothly and cut great threads. I used blue locktite and screwed the magnet in.

You can see the 8.5mm x 16mm hole here, looking up at my DKse filter housing


After I tapped the M10 x 1.25 hole and installed the magnet. Clearance and room for flow does not seem like it will be an issue.


After operating the tractor for some hours after the install I have noticed no differences in operational speeds or sound. All said and done, I'm out $35 and about 20 minutes of install time.
