I'm not trying to be a wise-a*s here, but I thought everything had been said, that could be said on this subject. The 1010s and 2010s are basically the same engines and timing issues apply equally to both. Here is a copy of what I posted a short while ago in this forum. I've heard similar complaints for years dating back to when the 1010s and 2010s were new. I've also heard the complaints about the Deere tech. manual being wrong and the IT wheel-tractor manual being correct. That has NOT been my experience. Just about all the fuel-timing and/or pump installation problems that I got involved in - were due to a misunderstanding of the literature - and/or using specs. for the wrong injection pump. We had similar problems with the 1010/2010 gas engines with distributor installation. The most common problem is getting the engine oil-pump drive-gear in the correct position - since it ultimately, drives the fuel injection pump. I've never used the book, or the special Deere service tool (AM450T). I don't find it necessary - I just stick the oil pump in, observe its position on the injection-pump drive end, and if it's not right - I take it back out and move it one tooth. I never found this to be a problem. In general, most diesel engines, if not timed properly, will spit, sputter, smoke, break-up, start hard, etc. - expecially when cold. They won't run smooth yet underpowered due to a timing problem. If your engine is running smooth - I'd suspect a low-fuel delivery problem. That being said, many Deere engines run better with the static fuel timing advance over what the factory calls for, and sometimes with some advance added also (to cut in earlier). Some early 3010s and 4010s that use pumps similar to some 1010s were set, initially, to fire at 10-14 degrees BTC instead of TDC. I've seen this work on some 1010s and 2010s depending on the individual machine and the specific pump that is on it. Once the injection pump is in, and the pump lines are aligned with the engine on TDC of compression sroke for #1 cylinder - you know the oil-pump is installed properly. You need to know what injection pump you have - with "load" advance, or "speed" advance. E.g., a DBGVC429-1AJ - the "429" indicates it is a four cylinder engine pump with .29" fuel plungers - and Deere spec. series "1AJ" that designates "load advance." Other pumps that end with "1DH" or "3AJ" use a speed advance for running fuel timing.
