Brand new L2501 started making a nasty noise at 6 hours

I know a guy on the youtube had a 2501, an he traded in in for a 3301 because it was so loud in his mind. He said the 3301 was not as loud.

I resemble that remark! Lol!

It was very loud. Very sharp exhaust note. I considered getting a muffler like my L3830 has and modifying to fit the L2501. But ultimately decided to switch with the L3301. Didn’t wanna mess with modifying a new tractor.

The L3301 is running fine. Also doesn’t have the 7.3L ford power stroke diesel smell like the L2501 had. My L3830 doesn’t stink like that. It’s possible I had a bad L2501. By the sounds of this post it’s always possible! Lol

He is rite...the 2501 is louder than the 3301. I think because of the big ole DPF on the 33. He can have his 3301. I traded my 33 in for a 2501 because of the DPF stuff....I hated it and it made the tractor unbearably hot to operate cutting grass in the summertime heat. They would be nice and warm operating in the North Pole or somewhere like that...ha hah a....not for me. I made a big mistake on that 3301 but I am very happy with my 2501. Can't tell any difference in power for what I do.

I think it’s because of the cheap muffler on the L2501.

My younger brother made fun of my "tinny sounding" Kubota, he said his John Deere has a proper diesel sound.

What model Kubota do you have? Normally Kubotas have a real smooth sound to them... typical Japanese quality. My ZD326 and L3830 have a great smooth exhaust note. But that L2501 I had made a whole lotta racket!

Nothing beats the sound of a big displacement John Deere Diesel. They really bark! (0:

Agree on the brown. Thankfully I never saw gray oil. If noticeably gray that could mean his engine ran too long without oil and he may have damage I suppose.

I've seen plenty of grey oil. Having had to handle equipment yards for a general contractor and road contractor for decades, plus my own private herd of junkers I've hauled home over the years. Byou can get any color of oil from black to white with the correct amount of coolant or water in there. Give drained a trans case that should have 85/140 in it that came out light ivory color like evaporated milk, because it had 5g oil, and 6g water in it...

Lots oil, water, metal based failures possible..need more info.

See posts 44 and 59. He found out what the problem was. Last we heard it was at the dealer for an engine replacement. Not an oil-related issue. Piece of metal in a cylinder.

I still figure that the mfr ran the engine a while before installing it in the tractor and heard nothing. Also since Arclight only ran it 60 seconds or so after the noise started. I'm still thinking that the offending clip/staple/piece of metal was lying there somewhere in the intake area closer the intake valves than the air filter and was ingested during the first 6 hours of operation. Maybe in the intake manifold, maybe in some of the air hose leading from the air filter to the intake, who knows. At least from the photos it doesn't look like a casting rim or fragment. Seems unlikely that it could have bounced around in there (say inside the combustion depression in the piston top) and then eventually bounced out on top of the flat part of the piston where there was no clearance. And it sure did not go through the air filter.

Agreed, could be debris, post filter and on/up into hose or intake. Finally migrated. Ouch.

Got a call from the dealer last night. The new engine has showed up and they're installing it this week, so I should be able to have it dropped off this weekend or early next week. Looking forward to getting the workhorse back, there's still much to do before winter takes over.

Good to hear that they are getting right on it.
