I installed a rebuilt injection pump on an IH 460 diesel last year. It may not be the same, so I probably shouldn"t even chime in here. Keep that in mind. First go around, I timed it 180 degrees off (exhuast stroke). The tractor would run, but not good. Took me a while to get it timed right, but it finally took off. Had to rotate it around again. Once in place, had to reference the flywheel, etc., it ran pretty good. Could then rotate the pump some for better performance. Seems like to find #1 cyl compression stroke, I pulled out the #1 injector, stuck a light rag in there. When rotating the engine, when the rag popped out due to compression stroke, that was TDC, compression stroke. I checked with a wire to make sure the cyl was up at tdc. I then lined up my reference marks on the pump and installed it. Does it run good with lots of power after warming up? Are all of the glow plugs firing hot. This 460 will miss a bit at first, but once hotter and good compression and heat in the cylinder, they all fire well with plenty of power. I also encountered quite a bit of black smoke. I found that my diesel supply line was not getting good flow from the tank. Had to blow out the lines and bleed at the filters and the pump. Once all air was out and gravity was providing good flow of diesel, it really ran great. When this 460d gets good and hot and firing well, there seems like there is not that much smoke. Please keep in mind though that I was working on a different type tractor.
