Equipment Haulers

When running down the road with no cover over the exhaust pipe, air flows in turning the turbo which means the bearings are turning with no oil pressure to keep them lubicated.

 

I've got raincaps on my equipment that sits outside with vertical exhausts, and yes, I always taped the exhaust on equipment I've moved, but just to keep rain out. If you have air "flowing" thru the turbo, where is it exhausting? It has to have a clear outlet to allow any flow. Think of a balloon, when blowing into it, it inflates, unless it breaks, then you have a path for flow, and you can't inflate it.

 

I haul equipment for a couple of manufacturers and both require the exhaust be taped before leaving the premises.

 

What you're saying is that the air circulates. Goes in and out at the same time. Impossible, unless it goes in and out elsewhere such as a big hole in a piston.

Please explain to us that when the air supposedly enters the turbo and turns it, where does it go ???????????????????????

 

Ya, you don't have flow, you have pressure. May be a little better analogy. Take a whistle, the type with the little cork or something ball in it. Go ahead and blow into it, yepper, the ball spins around inside. Now, block that hole, the ball won't spin because you have no flow, but you do have pressure.

Just an aside, You can't have flow without pressure, but you can have pressure without flow, and the more flow, the less pressure. In order for that turbo to spin, it needs flow through it, but there is no way to produce flow. The exhaust valves, intakes valves, in a cylinder would have to both be open to allow flow, and we sure don't want two valves open at the same time.

 

Not on all equipment. We also call them boom tractors but if you look at the Cat site they are known as Pipelayers.


It can't spin unless the air "FLOWS THRU". ### one poster said, blow into a balloon, where does the air go??? It certainly doesn't flow thru does it.

A flap is also used to divert the exhaust gasses away from the operator just like a curved pipe is usually turned frontwards otherwise you'd gas the operator.

 

If you're hauling new equipment from a dealer...many of them will make you cover the exhaust.

Just last week I loaded a Cat MT765c...they told me to be sure I covered the exhaust, and didn't give me the paperwork until they had inspected how I had it secured.

Painters tape is better than duct tape...it doesn't leave adhesive all over everything.

 

past month now i have been hauling JD tractors, was told that they have a clucth designed into their turbo to prevent free spinning so covering was not necessary.
