Dr Allis just brought up a great question on another thread I have. I have a 1970 Allis 185. It has an electric start on the diesel fuel injection pump. This is really unusual, and he suggests that the engine probably came from a combine. This engine has some flaking paint, and underneath the Allis orange is yellow. I always assumed that the tractor had been sparkled up at some point for resale and that either the yellow was actually really faded Allis orange or the tractor had been used by the road department in its early years. I'll add a picture. Please tell me what you think!  |

The numbers on this plate are 2800 4022412 2D-37896. I've been looking around for some list of years, makes and numbers, but I'm not finding one. I know 2800 is the engine series. I assume the 4022412 is the exact engine, and the 2D-37896 is the application this engine was put to (tractor, combine, ect.). Let me know if I'm right or wrong and what this thing is. I'm extremely interested now, and the internet is frustrating!

The yellow paint that you see is primer from the factory. The serial numbers you provided do not mean anything as the Germans threw out all the files when they invades in 1985.

| 2D-37896 is the engines serial number.....4022412 is the engine catalog number, or how the engine was spec'd. You'd have to find another 185 of the same vintage/similar chassis s/n to compare catalog numbers. Makes no difference.....185's never came with electric injection pumps. Either it's a different engine or a different inj pump. The injection pump tag number might give some clue as to what it is off of. |

If you can look the engine part(catalog) number up in an old parts book, it may give that catalog number, but just had a quick look on AGCO partsbooks, and they never list the complete engine there, that I found. Someone could have just converted the injection pump to electric shut-off for ease of installing murphy switches, or ?? ------------- 210 "too hot to farm" puller, part of the "insane pumpkin posse".

The 2D-37896 is the engine serial number not its application. The S/N was assigned near the end of the assembly line. Unfortunately there is no date code in the S/N. You're correct in that 2800 (D-2800) is the engine series. The 4022412 is engine catalog number and as Dr Allis points out is how the engine was configured for its application. There where several versions of each engine series for each plant (West Allis, Independence, Springfield etc). The color of paint that was applied at the Harvey plant varied as to which A C plant the engine was going to be shipped to. All of the West Allis engines were painted a "buff" green primer that looked like a "flat" pea green. All of the Independence engines were painted orange. Engines going to Springfield and Northlake were painted a bright yellow. As for the commercial products They were painted using the previous colors or Black, Purple, Dove Gray or Copper.
