knocking noise

[nosaj2]

My 2400H has clutch that is used to engage & operate the PTO. Does the 2515 have this also?

Clutch also removes drive power to the HST

no. It's independent PTO.

determine exactly how to make the noise happen and run it in to the dealer. nice its warranteed

They are coming to get it today. I prefer to have an idea of what is wrong with something before someone "repairs" it. But Diesels are new to me for the most part. Thanks for everyone's input. I'll try to post what they find and if it resolves the issue. I personally wonder if it is injector related. But like I said I'm not a diesel vet.

Sounds more like drive train noise - your test performed in 4wd ?- I dealing with noisy drivetrain in 4wd something out of alignment 37 hours into noise, New tractor. Dealer has call into factory for explanation have six year warranty. If it breaks they will cover it 100 % since I reported an issue. Nobody knows what it is.

My guess is the front drive joints. Have someone drive the tractor and you walk beside the tires. Jack the front end up and wiggle and spin the tires. Make sure they sound and spin the same. Check all rotating front drive parts for something loose.

My bet is something in the exhaust. I would start by checking the muffler.

No U-joints on these tractors. Straight shaft with splined couplers for the 4WD.

For the OP, since his tractor is an HST and doesn't have a clutch, I don't really know what the sound is.

On mine, is definitely something in the clutch. Probably just the springs on the clutch disc rattling around. Once it gets under load, it goes away. I'll take a inspection plate under the tractor and check the clutch stuff again.

I'm going with exhaust on this one too. The second vid really make it sound like a heat shield is loose. Does it make the rattling noise when the tractor is at full throttle but not moving??

No heat shields on this one though. Well, just one under the exhaust manifold but it's tight. It does make the noise while sitting but, the again, if I press the clutch, it goes away.

PTSG your situation since it is a clutched tractor almost sounds like it could be the throw out bearing. I think your in the right direction looking toward driveline. How many hours are on the tractor and does the tractor have a grease fitting somewhere down by the foot pedal that goes to the bearing.

In PTSG’s case it would not be the throw out bearing. When he pushes down on the clutch it goes away. If it was the throw out bearing that is when it would make noise.

In my case it was the clutch plate rattling when clutch is fully depressed. If I let off just a bit it goes away.
