There is no mystery with timing on 1010 and 2010 engines. In regard to the often referenced "discrepency" between the Deere an IT manuals in regard to injection pump timing - mechanically speaking, they are both correct - you just have to pay close attention to what you're working on. The Deere manual clearly warns "be sure each injector line is hooked to the proper injection pump outlet." The location of the #1 injection pump port was changed midstream, so it all depends on what pump is on the engine. With a 40+ year old machine, it's a "no brainer" to check which port squirts fuel when the pump timing lines show up - it is standard procedure for any old diesel with a rotary distributor-type injection pump. In regard to the timing line difficulty you're having. The lines on the crank and cam gear must be lined up, and the key ways are intact and cannot be changed - correct? If that's the case, there is one other possible variable. On the back of the crankshaft - if the dowel pin was left off, the flywheel can be put on incorrectly (I think). I've never tried it on a Deere - but I've seen it done many times on other equipment. If the flywheel is on correctly, #1 and #4 cylinders (the front one is #1) with be at TDC when the flywheel DC marks come up - it will do it on the compression stroke and the exhaust stroke. So, depending which phase of DC you are on, the valves for #1 might be loose, or might be tight. When the flywheel DC mark is visible, and #1 piston is on DC of the compression stroke, the injection pump timing lines are aligned, fuel comes out of #1 port, and said #1 port if hooked to a line that is hooked to #1 injector. Obviously, if you find that the #1 port is not where it is shown in the book - then the pump has been changed, no big deal, just hook it up accordingly. There is more to fine-tuning the fuel injection timing on a 1010 or 2010 and it depends on exactly which pump is on it.
