I've heard similar claims for years and still don't understand what they are based on. I worked for many Deere dealers and have worked on the 1010/2010s since they were new. I've rebuilt MANY of them over the years. I have never had a problem using either the original Deere manuals or the IT manuals. I sometimes like the IT manuals better since they cut out the fluff and just provide the basics. I've heard complaints for years about people not being able to time the fuel-injection pumps properly on the 1010s and 2010s. It is not complicated - not any more than any other tractor as long as you understand, and adhere to basic principles. First of all, if the engine has been torn down, the oil pump MUST be timed properly. If the oil-pump is out of time with the camshaft, you WILL NOT get the fuel injection pump in time. This because the camshaft drives the oil-pump, and the oil pump drives the fuel injection pump. Now, one oddity with the 1010/2010 series is that it is able run with the injection pump 180 degrees out of time. It will run BAD, but it will run. Now forgetting for a minute what make the engine is, and just sticking to basic principles - #1 the engine is put at TDC of compression stroke for #1 cylinder. #2 - the injection pump is put in "inject" position for #1 cylinder by lining up the marks in the timing window, #3 - the injection pump is intalled and tightened up with nothing changing - i.e. the engine is still on compression stroke at TDC, and injection pump is still at "inject" position for #1 cylinder. If these very basic principles are followed, and the injection lines are put in their proper places, it will work and work properly. Engine firing order is 1-3-4-2 viewing from the front of the tractor, and the injection pump rotates clockwise when viewed from the drive end of it. As far as these stories about pumps being 90 degees out of time when following instructions - I've heard it for years, but haven't seen it yet. Same goes for the teams of "expert" mechanics that have the similar problems. I think some people are getting their oil pumps out of time - but they should notice this right away when installing the injection pump. And there is also the issue of load advance versus RPM sensitive advance - but that affects the top end and not starting - and again, just requires proper adjustment. So, I ask - please explain what problem you had in a little more detail.
