Combines Air to Air on 2388

[TwinRotor]

If they will be built in the Twin Rotor factory they are bound to be better.

Care to back that statement with any relevant facts or relevant information for the poster's questionIJ Not trying to start a color war-I look to this page for good info, not gossip and color based opinions. There should be a TSB posted for trash build up in the air tunnel and in the air cleaner venturis. I have heard of operators putting a 90 degree elbow on the pre-cleaner and standing it up like the 21's, I have also heard of operator's making a hood to cover the top of the precleaner-leaving about 2 inches of space between the hood and the air intake. I wish I had a sketch or a pic to send. Check with the dealer, if he doesn't have any info, find another dealer or area man-there is info out there. Door sealing and rotary brush condition play a big part in cooling on the 23. Also check the speed on the rotary screen. I believe the spec is about 210 rpm. Good Harvesting-Have a safe one!!

In case you haven't heard New Holland bought Case IH. They have or are going to move production of the case ih combines to the Grand Island, Nebraska plant where the New Holland Twin Rotor combines are made. This plant is newer and more effecient than the East Moline plant where case ih combines were made. I found this info right on case's site.

Unfortunately, you are not the only one in SD that had this problem this summer with 2388s. We had several at our dealership as well. The best solution I have found is ClEAN, ClEAN, ClEAN the air-to-air aftercooler. Remember, it is the first cooler after the rotary screen so any material that gets by the screen_brush assembly gets caught in the air-to-air first. Add this with the fact that the coolers used on 98 and 99 production combines had a very fine tube and fin arrangement, too fine in my opinion, and the air-to-air would really lose its efficiency, causing the "S4" error code to go off. 2000 models with the more coarse cooling fins plus the higher temp. setting for the alarm have been much better about this, but they still seem to be susceptible to this problem as well. Most of those air-to-air aftercoolers I have been around could be cleaned for a half-hour steady and still have debris coming out of the fins. The best way I have found to clean the air-to-air aftercooler is to run the engine at the mid-throttle stop while you blow out the coolers, using the engine fan as a giant vacuum cleaner, while you blow out the aftercooler. Blow from both directions working back and forth and you will be truly amazed at the dirt that packs into the aftercooler. It doesn't help that the aftercooler is about the hardest cooler to reach from the access door, either, but proper cleaning is a must on these in our terrible SD summer heat. As far as the air cleaners, that is an interesting topic. I have heard of guys with 98 and 99 machines ordering an exhaust pipe from a 2000 and newer production machine that has only the one venturi hole for the precleaner. 98 and 99 machines originally had 2 holes as they had 2 precleaners, but when they were retrofitted to the ductwork setup like the 2000 production machines, only 1 was needed. Guys claim the exhaust pipe with just the one hole have better precleaner efficincy. Case engineering claims it makes no difference, but I know a couple guys who would say otherwise(perhaps the venturi on the old pipe was not working correctly, who knowsIJ). I have seen a few machines with the new style ductwork have problems sealing the air intake duct to the radiator_ccoling housing, drawing very dirty air into the air intake system rather than getting air from behind the rotary screen that has been "precleaned" already.

With all due respect, I thought your comment was about the quality of machine. Granted, Grand Island is a smaller, newer plant compared to E. Moline. It also has only a fraction of the number of engineers, manufacturing and field support personnel of EM. GI has only produced 1_10th of the volume that EM in the past. Producing both lines at even 5 times their current volume is a big task. NH combine engineeering is mainly in Europe with a few people in PA. They'll have to show me that they will be able to meet customer expectations in the North American market. TR, The last time I checked, Fiat owned about 86% of the stock in CNH. In my opinion, that's who bought CaseIH.

You got to wonder why case would put the inter-cooler infront of the radiator and not expect it clogg up.
