The purpose it to let the turbo cool down so the oil doesn't coke inside the journals. If it never gets hot its not an issue; the oil wont coke.

I keep getting a popup that says "This page has an unspecified security risk, do you want to continue?" And then you have to hit yes or no about 20 times to get it to go away.

BAP, sage advice. However please consider the very real condition that the owners manual is there to also protect them legally and may not be based on any reality other than a previous claim lost by them that resulted in a payout to a customer. Same reason your lawnmower says "do not stick...

PM'd you on the subject.

Does anyone have a service manual for a turbo tractor that can tell us what the intake manifold pressure at idle is? We can use this to establish a comparison. If you post pls post model and intake pressure, should be in inHG or mmHG. Thanks

Jerry, 1. q= 0.0638 psi. Mine was a little more conservative and is possibly due to ref. So lets use your number: .0638psi. This has to be multiplied by the area of the intake duct. Remember I said lets use a 3inch (7.068sqin) duct. That gives us using your number .45 psi in the intake. Im...

BAP, I'm not saying it cant happen and have even posted in concurrence with Jerry that it is theoretically possible. His statement of the phenomenon is accurate. I have not once said that the manufacturers suggestion not be heeded by anyone. However there's a lot of manufacturer suggestions that...

Kenny, I realize the manual says that. no argument form me that it does. However the physics doesn't work. In the case you've listed you load the machine on the trailer backwards, implying that there's a direct airflow into the exhaust. The same math and assumptions apply except with less...

Jerry, I think what you've stated is absolutely true, theoretically I wholeheartedly agree that theoretically it is possible. However I think I've showed mathematically that there simply isn't enough pressure at the turbo to make it spin. Even if we ignore all of the real things that are going...

why yes you have. Its the PSI over the area of object the force is being applied to. Our example 3in intake tube is considerably smaller than the aircraft engine. In a 5mph wind, if you had a 1sq foot plywood shield it wouldn't be that much of an effort (i can do the math if youd like) but a...

Now lets apply some basic reality to the situation to get some numbers and at least some Kentucky windage of the possibility of pressure in the intake rising enough when being towed to actually make a difference at the turbo. My argument is that there is NO pressure increase at the turbo under...

L6060 owner with DPF and 270hrs. No issues. I'm not sure why people have issue with emissions controlled tractors. Semis have DPF and millions and millions of miles on them without issue. Are there failures out there? Sure, but you have the same failures of any complex electronically...

EA makes great stuff. Not the cheapest, but you get what your paying for. I have compared my EA wicked grapple to other folks grapples in my area and the quality is way above on my EA. Thicker steel, better build, tighter tolerances. The quality is superior and the price is incremental.

Jerry, I take no offense by your post and look forward to a rebuttal; I didn't take it wrong or offensive. Its discussion, and discussion with math is even better. I've been a little slow in the thought process: Broke my ankle last sun and had surgery weds to pin all the pieces back in the...

Try that with your homeowners insurance....

Something else to think about: KTAC uses your dealer to assess damage. Your home owners is going to more than likely use a non-tractor assessor to evaluate condition and then they're going to want to apply depreciation to the age of the tractor. KTACs primary function is to keep a saleable...

From a safety margin perspective, I can understand Ks reluctance to suggest this mod. They don't suggest filling the tires on a 6060 either but I did. So here's the actual issue: If you make a non-recommended mod, will you accept the responsibility for anything that happens associated with...

Um, its not aerodynamics...its gas law. And a couple of really old physicist, guys like Bernoulli figured this out way before tractors. While I don't doubt your manual has a statement as such, lets walk through your theory for discusion. If I understand you correctly, when towing, there's an...

A. Venturi effect on the exhaust pipe produces NO measurable pressure at the turbo and certainly not enough to make it spin. This is a myth and complete misunderstanding of a turbo and the physics of pressure. If you think it does please provide a reference supporting your belief. Physics, its...

I think you first have to understand what idling prior to shutdown is doing and why there's perceived benefit from it. The idea behind idling prior to shutdown is to let the turbo cool to a point where the oil wont "coke" in the turbo. Coke is the solid residue created when oil undergoes severe...
