Axial-Flow Timeline

The separating area increase in the 1600 series was due to all the extra holes in the back half of the cage that the 1400s didn’t have. 

Also, the first CDC/Cummins engined 1680s did NOT have the long sieve. I’ve got a couple short sieve, Cummins-engined 1680s around here. 

Pretty sure it was 91-92 models, I quit working at the local dealership in fall of 90 & don't think they were out then.

I bet those are rare machines. Any idea what serial numbers both changes occured?

CDC/Cummins engines started at 1680 serial# JJC0045689, which was supposed to be around April 1, 1989. Ironically, it was supposed to be the same date that the Magnums came out with a 4-spd reverse and the “big numbers” disappeared from the sides of both the combines and Magnums. 

Long sieve 1680s came out at sn#JJC0047412, which should be an early 1990 machine. 

All CDC/Cummins machines did have the heavy-duty shaker drives, though.

40/60 machines didn’t have long sieves until the 44s/66s.

Back in '90 or '91 Dad bought a used '88 model 1660 with a Cummins motor that was supposed to have been one of the first 15 or so prototypes with the Cummins.  I dont have serial number info around anymore to share.  He traded it for a new machine in '93 i think.

Regarding SDman's comment shaker drives...can the early 1680 be upgraded to the heavy duty shaker drives?  Bushing seem to wear out too fast no matter how careful we are with centering/tightening the bolts.

First Axial-Flow combine in Europe returns to SIMA four decades after making its debut

https://media.cnhindustrial.com/EUROPE/CASE-IH/LATEST-NEWS/first-axial-flow-combine-in-europe-returns-to-sima-four-decades-after-making-its-debut/s/e79191d3-e471-472b-8164-b10ebfe77019

Forty years since International Harvester Axial-Flow combines were launched in Europe in France at SIMA 1979 / Original 1460 model as featured on stand to be displayed at this year’s show / Latest 50 series Axial-Flow models with Harvest Command make their first SIMA appearance .

The very first Axial-Flow combine to come to Europe is to return to the exhibition where it made its debut 40 years ago, with the restored International Harvester 1460 model to be displayed at the main entrance of Hall 5 at SIMA 2019. Visitors will find the Case IH stand in the same hall.

Think it was George 2 that had one of the last 1660’s made that had long sieves. Wonder if they didn’t let a few go out for testing or just make a change on the last few?

Our family owned the first 6 with the long shoe- JJC0047412-JJC0047417

it was also the first batch of Cummins with the 2150 high idle RPM, which didn’t work out (not enough torque curve) so when they brought them back up to 2650 they didn’t tell us  the large shoe drive pulley was smaller to keep sieve RPM up to speed with slower engine RPM!! Took about 15-20 separator hrs to shake the cleaning system out of a couple before Pro Harvest caught it and got us the replacement 5 sided belt and larger dia pulley 

Also this was part of the batch of 1680’s with soft piston rings so we lost 3 motors in ND at approximately 400-500 hrs when the rings let go crank case pressure would climb until it held all the oil on the top side and starved the crank and main & rods would go, sometimes a rod would come out the side of the block....

Late to read this. Interesting. The very last 1600's had the large sieve bushings and long sieves. The 44/66/88 had many of the updates used on the 2100 series including the splined unload auger(one piece) and the pfc hyd system. I was at the Case IH trade fair when they introduced the 2100 series. The auditorium was completely dark and BAM! They turned on the stadium lights on three combines. I got the same shivers as when I was sitting in the theater as a kid when the first few notes of the Star Wars theme song was played. Still have the dealer edition combine they handed out.

My Dad and us three boys were invited to the introduction of  the axial flow combine at AgLine International, Corpus Christi, Texas.  They fed us and then told us about how their new combine eliminated the straw walkers, the beater behind the cylinder etc. etc. etc.  And I'm thinking, "Oh good, you were able to lower the price then.  What?! you raised the price????"  I believe this was the year after Dad had just bought a new 915 combine.
