L6060 Engine Noise Getting Louder

[5030]

Wow a 100 buck hydraulic filter, that is crazy. The ones on my M's each take 2, are 30 bucks each from my dealer. One thing about Kubota filters and that is, don't matter where they are made, they are made to Kubota's specification. All I use is Kubota filters, no Wix, no Fram, nothing but Kubota filters.

400hr interval times 30 MPH moving average (for a car) would mean thats a 12,000 mile oil change. Seems excessive by any standard.

I checked the oil level a week ago and it was fine.

I check mine prior to each use and check the tire pressure every few weeks too

Idling a cold engine diesel or petrol is not recommended for any machine. The sooner you bring the oil up to operating temperature the better, just not under load. The oil pump is operating at a greater volume ensuring lubrication to all parts. A study was done back in the 1970s with two identical diesel vehicles working similar roles on highways, one was left idling 5mins to warm up, the other was driven soon as started. After 100,000 miles the engines were dismantled and all parts analyzed for wear. The engine that was 'warmed' had significantly more wear than the one driven immediately after starting. Sorry I cannot give the full details after all these years. The oil is the lifeblood of your engine and early oil changes can only help to extend the life of any engine, no need to wait for the clock. Usage should also determine a logical time to service a vehicle, especially after extended periods of heavy work loads. Often if I borrow equipment, especially small engines without an hour clock, I will change the oil before even starting the engine. Small price to pay foe security and also respect for the owner lending the machine to you in the first place.

There's NO WAY I'd let the oil go 400 hours in that tractor, not even 300!

I don't think changing the oil in that tractor will change that noise, and I don't think there's anything wrong with the tractor either...

Thermostat opening up once warmed?

Looks like I'm getting some heat for waiting 400 hrs between oil changes. It's actually been 320 hrs since the last change but close enough. I'm just doing what the owners manual says to do, mainly for warranty reasons. However, given the feedback here, I am going to change oil at 200 hr intervals from now on. I also use Kubota filters and fluids for all the maintenance requirements.

I contacted the dealer today and sent him the video. It will be interesting to see what he comes back with.

I am also in the middle of changing the engine oil and filter, front axle fluid, fuel filter and HST filter. Once it's all done I will see if it changes anything with the engine noise and report back.

Let us know if changing the oil changed the noise. I gree though, doesn't sound aweful to me.

I believe in following the owners manual. I figure the manufacturers have spent millions researching what works best on their products. My L5740 has a 200 hour oil change interval and the L6060 has a 400 hour oil change interval.

I figure it has something to do with the Tier 4 engines. They must run cleaner, therefore allowing the oil to last longer. But I'm not an engineer, and I don't know that for sure. That's why I follow the owner's manual guidelines.

I do the same on my vehicles. I change the oil when the computer tells me to. My Ram 2500 with the 6.4L Hemi gas engine goes about 7500 miles. My Ram 3500 with the 6.7L diesel goes about 13,000 miles before the computer tells me it needs an oil change.

That's why I love my Tesla. No oil changes!
