Have problem with engine air filter on CaseIH

[Hopperbin]

found a missing part of seal from the screen suction to other side of radiator, supposed to suck the chaff off the screen. put in sponge seal and duct taped the connection was hoping it would help, but still only made it 8 hours. The same time a rub bar let loose and we had to go home anyway so down for the night, get parts and put things back together tomorrow. Oh we slowed the spreader to the point it was not working but had to speed it back to 350rpm to get even spread otherwise it was bunchy, its still spreading 30 feet. Adjusted the flaps down. No avail on filter problem. Can't believe no one got a fix for this. Dealer did try putting a snorkel intake on extending 5 feet above hopper, did not work.

It sounds like it has to be a leak somewhere
between that snorkel and the filter. Can you put
a leaf blower on the intake to put a little pressure
in the system to feel an air leak anywhere?

Please forgive the earlier joke, I was trying to
add a little humour, but realized it might not be
appreciated when you're dealing with a frustrating
problem.

[Hopperbin]

No worries. I don't mind a joke thrown in. Back pressurize the system to find a leak or gap. I actually wrote that one down. Could card board and duct tape the rad to see where the air escapes easiest from.
What would we do without duct tape?

There another website that has plenty of historic threads. http://harvesting.com/combine
choose the Case IH and guranteed someone has experienced this and solved it one way or another.
Farm Ranger, I run CIH and that was pretty funny. I will use that one for the hired man when we are fixing.

Here is what I got from that harvesting.com/combine website.

If you are cleaning the filter and the asperator every day you may have a bad seal on the rotory screan. Also check the yellow wear strip under the rotory screan. If you see black areas on the yellow seal, you need to change that also. One of my 2388s was plugging the filter and asperator almost every day. The seal did not look that bad but I changed it any way and it made a world of difference. Make sure the tube from the precleaner, venturi, to the exhaust is open. Also all the tubes in the precleaner must be open. Your problem should not be happening every day. Maybe every 500-1000 acres but not as you say.
It(yellow seal kit) is a service item to be checked after initial 200 hrs and every 50 hours after that. 87302735 from the Case-IH update/kits book I have.

Yellow seal kit are you talking inside or outside the rotary screen. I am fitting a black plastic tube in a perfect arc from muffler to pre cleaner now. Leaving to get parts now for broken rub bar damage.

I am checking into rotary screen seal, seeing if can move screen closer to door.

We had big problems with that in canola on our 8010's.After we slowed the chopper down and droped the chopper knives to the lowest setting we reduced the plugging alot.After doing that the straw was still pretty fine but made a big difference.We also bought an extra set to have in case we plug mid day but that hasn't happened since we made the changes to the chopper.

[Hopperbin]

checked into the seal kit and it was just for the 2388s. Did the wood block and hammer trick to the screen door to make it fit closer on the hinge side. Put the new level tube to muffler on. Did actually adjust chopper knives to the lowest setting this morning after repairing them. Even combined 2 hours in very tuff conditions this morning and , wallllaaa, filter still plugged after 8 hours almost to the minute.

Dealer give me a new filter housing with holes drilled in the precleaner and a rubber strap wrapped around it. So can easily take the strap off and blow out the pre cleaner without taking the whole housing off. So guess will go with this for the rest of harvest. Filter change mid day and blow out pre cleaner in morning. Can live with that for now.
