D8N (9TC-1UP) Venturi not working - collapsing air filters?

samedi 29 octobre 2016

We are working in fine alluvial silt (raking) and the following radiator is after 5 hours. It is also contribuiting to our overheating.

From what i can gather, the air intake sucks it though the spiral pre-cleaner, the particles get pushed against the wall, and the venturi (that relies on negative pressure from the exhaust) sucks the dust out from the side?



Closer inspection indicates the venturi (low RPM) is blowing air (positive pressure) instead of sucking. Higher RPM, it is faintly sucking but mainly blowing.

Would this indicate an exhause leak somewhere in the muffler?
