Do You Cover Your Vertical Exhaust Stack Tip While Trailering?

If this is the case, it made me wonder if starting your tractor with cold oil can't be harmfull to the turbo as I imagine it doesn't get oil immediately.

I think that would only be a problem IF you were to immediately put it to work. Depending on how cold it is out, most manufacturers of engines dictate that we should let them 'warm up' for a certain amount of time. This is to let the oil and engine warm up.
Although the turbo spins when the engine is running at idle, it isn't spinning fast enough to do any damage with the cold oil.

When my used JD 6415 was delivered by Semi truck & trailer, the exhaust was covered. Not worth the risk when covering is so simple.

I trailer an MX5100 turbo and stuff a paper towel in the exhaust. I think tractor makers now try to tip the exhaust so the air stream doesn't hit the pipe just in case the operator forgets. Damaging turbos used to be a concern and there were prominent warnings in the owner's manuals.

I have a 2007 TD95D and my operator's manual makes the same recommendation. It certainly is a possibility that the turbine can windmill under those conditions. Why argue about whether it's a real problem when $0.03 worth of duct tape can close off the exhaust?

When ever I've had any equipment with a turbo low bedded the drivers have always stuck a rag in the exhaust for the reasons mentioned.

Just a side note on stuffing a rag into the pipe when trailering. I took my NH T4.75 with Tier 4B in today for the 50 hour service and stuffed a small white hand towel into the stack about a foot down with 2"-3" sticking out the pipe. When I arrived at the dealership I pulled the towel out knowing I would have to throw it away from being dirty and it came out clean and white. You cannot tell it was ever in the exhaust pipe.

I've always just stuck a paper towel in the exhaust. Then when I forget to remove it, which is most of the time, the exhaust pressure just pops it out. It doesn't need to be pushed in hard or taped closed.

It's a good idea to cover the exhaust pipe. I worked with pipeline welders a few years ago. They were all diesel machines sitting in the back of the truck. A couple of them forgot to cover their exhaust pipes. The machines had problems after that. The welders said they "dusted their engines".

Basically they had dirt and grime from the highway get into their diesel motors from the exhaust pipe ruining the motor. If the motor is running however, it is not an issue.

This is strictly my opinion.

Wive's tale. As we Missourians say.

No way, no how that vacuum or air pressure is gonna spin the turbo enough to ruin the bearings. Remember, there's no load, even if it would be possible to spin it, which it is not.

I live along Interstate 35 hiway in Northern Missouri. If I travel the Interstate it is very common to see new JD equipment being hauled South from their plant in Iowa. None of them, regardless of type of equipment, i.e., Backhoe, Grader Dozer, Skid Steer, CTL, etc., have their exhaust pipes covered. NONE OF THEM. Graders are 99% hauled backwards with their huge exhaust pipe pointing forward. Not covered.....

Makes for a great discussion though, with plenty of experts.
