superih Posted January 17, 2017 Share Posted January 17, 2017 Looking at a 2006 2377, I know these had the 8.3 cummins but are they a CAPS engine or still mechanical fuel pump? thanks, Link to comment Share on other sites More sharing options...
SDman Posted January 17, 2017 Share Posted January 17, 2017 Neither. A true 2006 production 2377 has a high-pressure, common rail electronic 8.3liter engine. Link to comment Share on other sites More sharing options...
superih Posted January 17, 2017 Author Share Posted January 17, 2017 Could you please educate me on these 2377 and 2388's? They are the same machine just 30 horsepower difference? It appears 2004 was when the rotory cleaner was moved to the right side, these are the ones made in Grand Island and supposedly the better machine to have? Did any years come with a CAPS engine or did the combines only have mechanical or common rail. thanks a lot. Link to comment Share on other sites More sharing options...

SMOKER 1 Posted January 17, 2017 Share Posted January 17, 2017 There is a serial number break but yes, a true 2006 model has the fuel rail system. With out going out and looking I think the serial break was 254,xxx and up. I don't believe the CAPS system was ever on a 2377. 2377 and 2388 were the same except for HP. I put a tuner on mine and on the low setting it will run rings around a 2388. Fuel consumption is a whole different animal! jerry Link to comment Share on other sites More sharing options...

SDman Posted January 18, 2017 Share Posted January 18, 2017 2377s and late 2388s are the same except for the HP rating and grain tank capacity. The 77s didn't have those little 6-8" tall factory "bin extensions" so their bin capacity was listed as 20 bushel less(190 vs. 210). Some prototype/preproduction 2377s were built at East Moline, but all factory machines were built in Grand Island. The later ones with the HPCR engines do have more power, but they are thirsty under load. I had a 2388 with that engine burn 21-22 GPH under load last summer(however, it was running a 36' draper head and a Redekop straw chopper in 70 bpa wheat, so it was working its tail off). Also, those engines had a lot of injector trouble(many ruined engines because of the injectors). The 2005 model engine is a mechanical 2-valve engine. As far as "better machines" coming from Grand Island, some would debate that. When they started Axial-Flow production in Grand Island in 2005, there were some assembly issues to be straightened out. You have to remember, they moved Axial-Flow production from a plant that had built them for over 25 years to a plant that had never built them before. These issues were resolved rather quickly, but there were some problems with build quality for a little while. The nicest thing about GI machines is that all the parts are painted before assembly, so the bolt threads on all of the bolts holding tinwork together don't have 3 coats of paint on them like they did at East Moline. As far as CAPS engines, the only red combines that I am aware of that had CAPS engines were prototype AFX7010 combines back in 2002-2003, according to information I have on the early AFX machines. When the full production of the 7010 came along, they had a Iveco/FPT 9L engine. Link to comment Share on other sites More sharing options...
superih Posted January 18, 2017 Author Share Posted January 18, 2017 So fill me in on the injector problems, ruined the engine from fuel in the oil or burnt pistons or?? Link to comment Share on other sites More sharing options...
SDman Posted January 18, 2017 Share Posted January 18, 2017 Most common problem when they were new was that the injectors would stick open, fill the cylinder with fuel, cause hydraulic lock, and then have massive engine failure. It takes about 30 seconds under load for this to happen. Also they would not fully open, causing a noticeable miss/flutter/smoke. Had burnt pistons due to this, valve/cylinder head failure. What I've never quite figured out is that these engines were also used in Magnums, small Steigers, sprayers, and other machines-they never had near the problems with injectors as the combines did. The combines do have a different fuel filter setup, and I've always wondered if this was the cause of the problem on the combines. Also, in 2006, the went to a different rotor drive gearbox and rotor belt. 1998-2002 machines with the rear-mounted rotary screen used a different gearbox/rotor belt setup, and then the 2003-05 machines had a different gearbox/rotor belt setup as well. There are 3 different rotor belts on a 2388, depending on vintage of machine. 2005 models started at HAJ292001; 2006 models started at HAJ295001.

SDman Posted January 18, 2017 Share Posted January 18, 2017 Nothing major, just some minor improvements. The Pro600 color display for a yield monitor replaced the black & white Universal Display Plus display. The 2588 offered a factory bin extension that gave it an extra 50-60 bushel(I don't think that extension was offered on a 2577). Unloader capacity was increased(sprockets changed on the unloader drive). The unloader was a little longer and was anchored to the top of the grain tank frame. Second gear was wider. Also introduced was the metal rotary screen instead of the plastic one offered on the later 2388s. Skirting was changed around the spreaders to reduce material building up on the rear axle.

Cliff Neubauer Posted January 18, 2017 Share Posted January 18, 2017 The 25s also offered the centralized header latch as a factory option and it was released for field installation on older machines. Link to comment Share on other sites More sharing options...
