John Deere generator filter ... BT259 ran 3,850hrs

[oil pan 4]

I've got an old John Deere generator, 50kw, I6, turbocharged. The oil probably saftykleen was last changed about 2 and a half years ago. It's ran up 3,850 hours, has 6,811 hours total. The oil stinks like used diesel oil bad.
The oil filter on these sits upsidedown and tilted there is definitely some sludge.
Docs were changed over and I think this one just got skipped, probably intentionality. Old hours were written on the filter.
Did they change the oil a year and a half ago? Maybe, but probably not.
Otherwise it runs fine, smoked a lot on startup.

Sludge

I would love to see a UOA on that oil.

None till this morning and after digging around for a bit I found some hidden wix 51243 and then filled it up with about 4 gallons of saftykleen 15w-40.

Had to get a coolant pump for this one too. So now I know for sure what it is.
Is a John Deere 5.9L model 3179.

Base of the filter up or down? Everyone defines the "up" side of a filter either way.

Think of the wrongest way to mount an oil filter. Like a Subaru. That's how John Deere does or did it back in the day.
The most correct way to have the oil filter installed is so you can fill it with oil and screw it on.

I would like a picture of the generator itself

I enjoy the inverse mounted or laterally mounted filters and all the spills that happen when trying to prime them before installing. It's a sweet joy of making even more of a mess than you're already dealing with.

So base down.

My Tacoma has a vertical base down mounted filter. I can pre-fill it just enough to soak all the media and can still install it without spilling any oil.

It can be done it takes training and focus.

Depends on if EJ or FA.

Sounds like a nice machine. What’s the story behind it?

Is it an actual JD with a JD engine or is it a rebadged Yanmar thing?

It was supposed to be a backup generator, probably used it in place of properly wiring in stuff. Or used it instead of paying to have 3 phase ran out somewhere.

It's almost as if the OEM realized prefilling the filter isn't really important and user convenience was something they wanted to offer. SMH.

Cummins oil filters are always mounted vertically and base up (i.e. the normal way) so they spill less when you remove them. While it allows you to prefill the filter, that's not the main reason for the engineering direction to always have designs with the filter oriented vertically.

Lot of very durable and reliable engines have been built with oil filters mounted sideways or "inverted."

My only issue with threads up is it allows the sludge flecks collect at the bottom, right next to the bypass valve.
Its probably not a problem.

That's why Ford used filters with a base end bypass valve. Most old Ford engines had the filter mounted at a 45-degree angle from horizontal with the base upward.

My dodge is like the too.

Do Dodge OEM filters have a base end bypass valve?
