Kubota Hydraulic Filter on a New Holland?

[mrmikey]

I'd just get a couple of those rare earth magnets and stick them on the outside of the filer, take them off and reinstall them on the new filter when you change it................Mike

My viewpoint is different from your viewpoint. If metal fragments are in my Kubota trans reservoir I'd rather have a magnet catch the particles than have the particles be floating around & end up in hyd pumps,brakes &/or hyd valves. 1st time I changed my M7040 hyd filters there were some metal particles on magnets but subsequent filter changes there was only a very small amount of metal filings. IIRC the magnets don't block holes in filter base to any extent.

If you have metal fragments floating around the inlet side of a filter they are gonna be trapped in the filter in short order. Oil flow will carry them to the fliter media, they aren稚 going to move against the oil flow back to the sump.

I'm in the camp of a magnet not being "necessary", but certainly not hurting. I remember a tip from high school auto shop was to check the engine oil drain plug for what it collected, because many were magnetic. Part of the benefit is to take all sizes of metal particles out of the oil, and also to give you a visual hint of internal wear. So, an exposed magnet (drain plug or Kubota filter) will give a visual. A magnet on the outside of a filter, case or pan, not so much. My F-150 and Subarus have transmission magnets (that you can't see unless you pull the pan). Of course, a magnet will only show you the ferrous metals, and some wear, like journal bearings, would not necessarily be caught. That's where oil analysis helps for wear diagnosis.

Blackstone did a newsletter on a similar subject. Answer: inconclusive

Engine sump magnets are a different discussion. They collect ferrous metal before it enters the oil pump which is typically before the filter, not after it as with most hydraulic systems. There’s no disputing the value in that. A magnet stuck to the inlet plate of a filter or to the exterior of the same filter provides a feel good vibe but probably does not stop anything more than the filter media would without the magnet.
Like I said previously if it makes you feel better, have at it.

After some more thought on this subject I'm going to agree with YOU!! :drink:
