""""Great pics. What is that grey pipe that looks like it connects to the top of the exhaust pipe?""""
That pipe frovides air flow and extracts the dust from the cyclone precleaner you can see in other pictures. There is an eductor (I believe it's called) in the pipe to create the suction. If it's rusted out, you just get a lot of soot in your air filter!
I have a 9860 STS runs but only just at 270RPM checked fuel coming out of tank and screen there and fuel filters they seem ok, any other suggestions? What fuel pressure should I be getting at the filter housing? Any help much appreciated.
We have 3 D635 and have always had lots of header height ground following issues. We have done lots of calibrations and changed sensors. Someitmes they work but for the most part we have to run manually. Any one have any solutions? We are thinking of trying headsight header height control.
