Cummins and case IH motor partnership questions.

[GeorgeB230]

Wondering if Cummins stopped making motors for case IH. And why they are called FPT motors now. I just learned that when they went from the 8.3 Cummins to 8.9 I thought it went from a Cummins to a Fiat motor. But I had looked and saw that it was just a larger Cummins motor in the next gen magnums after the Mxs. And I think now the magnums still use a 8.9 but they must have changed because of emissions. Also are the 8.9s good motors compared to the 8.3 and do they make a lot more power.

I think it would be cool to do a swap in a older magnum with a 8.9 or a 400 big cam

FPT is Fiat Power Technologies. Fiat is a massive Italian company. I think they own part of Case IH now. They licensed some Cummins engines and they build a copy that is just as good as the original in my opinion. They also build their own engines which are very good.

Once the high horsepower rowcrop tractors started using def, they went to a fiat 9 liter engine. They did stick a cummins.9 liter in the later 305 and the 335 tractors.

CaseIH quit using Cummins/CDC-sourced engines in tractors late 2010/early 2011 when TierIV emissions began. Some CaseIH products besides tractors(4420 sprayers, 50/60/7088 combines, 3520/4520 floaters) used Cummins/CDC engines up until late 2011/early 2012 build when TierIV emissions began across the product line. Since then, pretty much all engines for CNH products are from FPT. Fiat owns CNH....Fiat owns FPT....they look at it as "why use someone else's engine, when we can use our own?". Kind of like IH back in the day.....how many IH tractors were produced with non-IH engines from the factory? Not very many.

The Cummins/CDC 8.3L were all 2-valve, mechanical engines from the beginning of the Magnums and the very last baby green Steigers up until 1998 or so. In 1999, the 4-valve electronic 8.3L CAPS engines were introduced on the MX240/270 tractors. In late 2000, the CAPS 8.9L(most places refer to it as a 9L engine) debuted on the STX325 Steiger. In late 2005 or so, both the CAPS engines and the 2-valve mechanical engines were retired and replaced by the HPCR(High-Pressure Common Rail) electronic 4-valve engines....which were available in 8.3L or 8.9L(again, most places refer to it as a 9L engine). These were used through the end of Tier 3 emissions in CaseIH tractors.

Since Tier IV, the engines that replaced the former Cummins/CDC engines in most CaseIH applications are the FPT 8.7L, which is commonly referred to as a Cursor 9L engine. FPT calls their larger engines the "Cursor" series; Cursor engines have been built as a Cursor 8, Cursor 9, Cursor 10, Cursor 11, Cursor 13 and Cursor 16 in different CNH applications through the years)

Well said. Here are some technical details that back up SDman’s overview:  https://www.industryweek.com/leadership/companies-executives/article/21950276/cummins-to-conclude-joint-ventures-with-cnh-and-iveco

In my opinion, those CDC engines have reached legendary status among the all-time greats.
