Not all folks care to join FB. May I suggest that you provide a standalone ad?

I can bust that myth quite easily. A few days ago I was able to capture a picture of Santa Claus with our grandson. And that's that.

Our son's buddy just installed one in his truck camper. Too soon to offer any review.

👏

Even Fleetguard punts on that one.

Good point. If the guy starting that engine hadn't charged that engine, Snappie should cut him off from all future purchases.

From the Service Manual for the Signature, ISX and QSX15 Engines, Volume 2 I should note that the page provided demonstrates a rebuild in progress.

Agreed. I've heard rumors that CDL examiners will flunk the poor soul they catch floating gears. You would think an operator who can float gears would be able to use a clutch as well.

A turbo on an ISX will cost you north of $2K. Then there's your labor. If you're an O/O, that's real money. Honestly, I have no empirical evidence to provide which demonstrates the value of the manufacturer's recommendation, but it makes perfect sense to me that turbo bearings and a shaft which go without lubrication could prematurely wear over time. I don't have the money or time to burn so why risk it? Although not exactly an apples to apples comparison, it's the same reason why I'll allow my coolant and oil temperature to drop before shutting down the engine after a hard pull. Oil can coke on the turbo shaft and bearings and result in premature wear. In both examples, it's a case of treating a critical engine component with kid gloves. How about we agree that the original declaration isn't necessarily a myth. And then there's the whole commercial use versus pleasure use argument...

Ahhh...the 855. It's a beautiful thing.

Interesting point. I've wondered what kind of truck and engine we would have if good designers got together without federal and economic constraints.

Rick, I'll make sure I change my oil at home before we visit in February, lol.

There are many diesel engines with vertical filters. And there are very few gas engines with turbos. How long does it take to pre-fill a filter? Again, I'll follow the manufacturer's recommendation.

Whether or not you pre-fill or not is entirely dependent upon engine design, specifically the route the oil takes through the engine. Take the Cummins 6.7L for example. The oil feed for the turbo comes straight off the oil filter head. The oil filter is pre-filled during an oil change to ensure the turbo bearings don't go without lubrication when you crank the engine. Hmmm...I wonder if other Cummins engines have the same design. Feel free to argue that wear over the life of the engine is minimal. The designers of these engines are smarter than me so I'll follow their recommendation.

LOL...that's not a myth, but it could start a good fight!

Well, you never did get a ride in my truck. It was FAAAST!

Hmmm...myth or hack? LOL...maybe I just can't stop thinking about power dividers. https://youtube.com/shorts/hT9j8cIDy9E?si=4aij172hL6fBQdSx

Uhhh...nitrogen gas in your tires is the shiznitz.

So what you're saying is that you drive your truck with the power divider locked? Don't forget, you can have both an interacted lock and a differential lock. Interaxle is like limited slip on both axles. Diff lock is like having positraction on both axles. I always start with interaxle then lock the diffs if that is not enough. Maybe we need a dictionary before we try to kill old myths.

I put that s...t on everything. Good stuff.

But in your live tandem example, that front axle is still "dead" 99.99% of the time...give or take.

What part of what I said is I correct? Secondly, in a tandem axle/rear drive axle configuration, why is the rear axle used as the drive axle and not the front?

Rick, maybe I'm not understanding what you've said here. You can spec a tandem axle tractor with a power divider that gives you the ability to have two drive axles. You can also spec that same truck without a power divider where you're drive axle is only the rear axle. In the case of the truck with the power divider, you would NEVER engage the power divider under normal driving conditions so why wouldn't that front axle be "along for the ride"? Again, assuming you haven't driven over a banana and need to engage the power divider.

My Last Will and Testament had my gravestone saying something sweet and caring about my family...and the dogs. I need to call my attorney and change that.

$185 an hour? Consider yourself lucky.
