Have problem with engine air filter on CaseIH

[Hopperbin]

We were blowing the engine air filter out every day in the wheat. Now into this very dry dusty canola we are having major problems. The pre cleaner keeps plugging up, anyone got any fixes for this?

What we did on our 2188 was put a 4' extension on the intake to raise the precleaner out of the dust. You also have to extend the aspirator hose as well, but it made a huge difference for us.

join the club, been fighting that
for couple years.
if yours is an 02 with plastic shroud up top , its the worst.
you can fight trying to seal the leaks and get fine screens and improved seals for air screen .
your precleaner could have the tubes melted out. yes
spend lots at case for no results.

or get the air intake close to the height of hopper topper , with some kind of precleaner and screen.
now it's about 50% better than 2188

a standard 2188 is 5 times better than the 23 before the fix

If this is a new combine you have to blow out the holes in the tube leading to the filters. Update coming apparently.

When all is working correctly, how often does the filter need cleaning?
Old 9600 goes all harvest.
Rotaries are way dustier, IMHO.

Take a look on thecombineforum lots of discussion on how to address the issues with it plugging. Just search for 8120.

I checked the combine forum, some mentioned door seal and warped screen plate as some problem areas. Dusty dry canola seems to be the worst. We cannot make it a day after cleaning the pre cleaner, apparently it is the thing plugging up then the filter must take all the shit coming in. So we are working on it this morning. We had the filter housing off 6 times now to clean that pre cleaner, so we are paying some attention to door and screen seals. There is some chaff coming in some how. We are reducing our spreader speed more today also.

Hopper, here's a quick fix.

1.  Loosen air cleaner bracket.
2.  Remove combine.
3.  Reattach to later model JD combine.

Should work.  ;-)

Our 9650 sts has gone through the harvest with out cleaning the filter...I think the JD's have a better chopper that throws the straw and chaff farther from the machine...
