Build date

About all you can do is look for a casting date number on the block and that would be close by a year or so. A model 670-T was first used in late 1977 in the 7045 tractor and L-2 combines. It would have had a Stanadyne injection pump and A-C injectors. Painted black for a tractor and orange for a combine. In 1980 the combine engines became black and Bosch injectors were late 1980/81.  M-100 Bosch injection pumps came in 1982 in model 8030 tractors and L-2/L-3 combines. The type of flywheel also is a clue to tractor versus combine. If it has a hydraulic pump drive on the left side it might be from a New Idea Uni-Harvestor.

Dm4629 pump. 3 groove pully on crank   Fly wheel i don’t know. Was told it was out of a n6 combine but I’m thinking it was a n5

There appears to be an auxiliary drive plate bolted onto the back of the front engine plate. I would say combine engine. They must have the water filter tapped into another location because they aren't using that block drain.

Pump has had work done to it with all the XXXXX.  2300 RPM means 7060. Manual shut-off means tractor. Electric shut-off means combine.  DM4-629 means 7060 or N-5. Rubber crank pulley means tractor. Fluid crank pulley damper means N-5 combine or 7080.  4 inch exhaust pipe means N-5 or 7080.   3 inch exhaust means 7060.

Yes it’s a electric shutoff    I was always told it was out of a N6 but from you guys know it appears to be a N5 it sounds like and around a late 80 to 81 model year
