Hi all,
We hve a 2005 Crescendo with the caterpillar C7 350 HP. I have had problems with the air cleaner on the unit since day one and was wondering if anybody else has the same experience.
The gauge that measures the air flow through the filter reads all the way to the top almost all the time. I change the filter more than neccesary so I know it is not that. I have removed the hose, both ends and tried moving air through it and all seems ok. I can reset this unit , drive a hundred miles and it is pegged at the top.
The air intake is about 5" and the hose from the air box is also 5" so no restrictions there. I wonder if I need to open the intake hose to a 7" coming from the box and then reduce it down to 5" as it enters the filter.

Anybody have any ideas?
