Equipment Haulers

Then why don't the equipment dealers put buckets on all their equipment they have sitting in the yard. Surely it doesn't rain only when you're hauling.

If you had rain fill up the exhaust system it must have been during a monsoon season and the equipment was submerged.

FGollow the exhaust pipe and somewhere along the way you will notice a small hole at a certain location that allows moisture to escape.

Why is it when a trucker parks for the night with the engine shut off and it's pouring rain that his exhaust and turbo don't fill up with water??????? And a lot of trucks have straight pipes only with no elbows.

I bet you run out and put a bucket over yours.

 

Here's the inquiry I made to Caterpillar.


Is it imperative to tape off (block) the exhaust pipe when transporting? I can't see how the air could flow thru unless you had a big hole in a piston or something.

It is possible that a slight vacuum pressure might take place but certainly not enough to cause the turbo to turn.

Equipment can be left out in the open air for days and weeks in windy conditions without it being blocked. Again, I can't see the wind causing any damage.

Lastly, if wind is a problem while transporting, why isn't the air cleaner being blocked off as the air can enter at that point and get to the turbo. The air intake 14" in diameter has a much larger surface for the wind to push thru than a 5" exhaust pipe.

I would appreciate your response.

A 14" diameter with 5 inches of open screen height has 220 square inches of open surface. While a 5" stack has 7.85" square inches only. A 6" has 6 X 3.14 = 18.84/4 = 4.71*2 = 9.42 square inches.


Maybe your blocking the wrong end!

 

Please delete another one. Thanks

 

Oh my god, they cant do that!!! What if a meteor falls from space and plugs it up?!?!?!?!

Seriously man, you are making way bigger of a deal out of this than you need to be.

If you don't tape em, don't tape em.

But I will say I do get a chuckle of the "Because it hasn't happened yet it isn't going to" line. Saying that is about as smart as saying "Well I drink and drive all the time, I have never been caught, been doing it for 20 years, never had a problem."

 

Why are the stacks on new trucks not taped when they are piggy backed?

 

Because they are running in the turbos with a light load before the real work starts.

 

Often times they run those trucks down the road with out the exhaust on them, and when you are running a truck with 2 piggy backed on it, the stacks still point backwards.

 

Just got this in my email. I was hoping to talk to an injunear. Not that a mechanic wouldn't know the answer, but I'd rather hear it from R&D. If the answer is email, I'll post it, if a phone call, you guys will have to trust me.

While PB has stated that he has hauled equipment for years without covering the pipes with no ill effects, it was not presented as proof that "that means it's OK". It was presented simply to show that he has lots of experience regarding this subject. If you read his posts you will find that, on several occasions, he has explained the 'mechanics' of why covering the exhaust in not necessary.
