John Deere TECH Calmar

Ethan and Amy 8.1L

Goldilocks lives again! Amy and Ethan had this 8.1L electronically controlled inline engine. Every year it gets a little cleaner. They had a little injector issue but in the end it ran very well.

John Deere Tech!!

This was the year that we decided that we would do the 13.5L engine that we have had for a few years. It had a rod and crank issue and some problems with the timing gears. Dakota and Levi took on this challenge knowing that the mechanical issues would be the easy part. They started working on the electronics in February by starting with a controller and then building a CAN bus system. The electrical project involved mornings before class and any other free time. It has developed into a hybrid system with combine controllers, a 9L fuel pump and various other used and new parts. In am expecting RPM as soon as we figure out what a matrix has to do with the engine speed.

Spare parts!!

Sam and Josh 8.1L HPCR

Sam and Josh had a 8.1L HPCR engine and they also took on the challenge to build a wiring harness. This is the other half of the not so pretty but it works team. If they had a little more time it would have looked as well as it worked. They had a little injector issue that got them some diagnostic time.

Brian and Garrett 9.0L

Brian and Garrett also had a Tier 3-9L. When they were finished with the engine they also were challenged with a wiring harness. Wiring diagrams were the highlight of there day for many days. They worked with their classmates and the 4 of them combined their efforts for a successful adventure. Make sure you notice the IVT transmission shift lever that is being used for a throttle. Dual channel hall effect potentiometer right Garrett?

Kevin and Nash 9.0L

Nash and Kevin worked on a Tier 3-9L for their engine project. When their engine was done they were challenged with building a complete wiring harness. That turned out to be a larger challenge than time allowed so we combined forces with the neighbors and each of the 4 students took a section of the harness that they were responsible for. In the end success!

Kyle and AJ 8.1L HPCR

Kyle and AJ also took on a wiring challenge this year with their 8.1L HPCR engine. They were part of a team that built a complete harness. It may not be pretty but it works!

Matt and Luke

Matt and Luke had the 466 mechanical inline pump this year. This is a 4440 engine with a different pump on it. They found the big muffler for it but it didn't last very long.

Kollin and Nathan 12.5L

Kollin and Nathan got to use the new jib crane this year for their 12.5L. They verified their wiring harness and used the Picoscope to determine the settings for the pulse width modulated throttle. It had a bit of a miss when it first started so they also got to practice their diagnostic skills as well.

Logan and Nolan 6068

Logan and Nolan did the 6068 combine engine. This is a Tier 3 four-valve engine with quite a collection of electronic components. The harness for this one came with some pre-installed electrical issues from last year so they also got several hours of schematic training.

Lucas and Corey 9.0L

Lucas and Corey had the first 9.0L to run. They also took on a wiring harness challenge. They used an engine harness and built a harness to connect the engine controller and the armrest controller. After several days of wiring schematics and more wire connectors they got it to run.
