This is a pump for a Deere 40 or 45 combine with the HA-165DĭBGVC429-2DH pump has fuel set at 1.964' and 10 degrees engine advance at 2000 For that reason, it makes sense to experiment by the position of the pump when bolted to the engine.ĭBGVC429-1DH pump has fuel set at 1.957' and 12 degrees engine advance at 2000 That is a huge difference and can make a big difference in cold starting. So, installing any of the many 2010 pumps, with those timing lines lined up - can vary by 3.5 pump degrees which equals 7 degrees at the flywheel. And, that's pump degrees which is half of engine degrees. Some other 2010 pumps have them at 47 degrees or 50.5 degrees. The pump you have right now has those marks etched on at 48.5 degrees. Those timing marks are etched on by hand when the pump is put together, rebuilt, etc. Unless you have the specific pump specs, you don't know what it actually means when those lines are lined up.

When you install a pump on to the engine, and line up the timing marks - you are kind of doing so blindly. The timing marks can vary with different model pumps and that can make a big difference in cold starting. 2010 engine was new and so was the injection system. So, there was a lot of trial-and-error over the years by Deere and Roosamaster/Stanadyne. In fact, the pumps were new to all tractors of any make (I think Hercules got them first).

10 series were the first Deere tractors to ever use the Roosamaster rotary pumps. I don't want to get overly complicated here, but I guess I don't know how not to. The timing at cranking does differ though with some other pumps used on 2010s and that can make a big difference in cold starting. Advance makes no difference with starting. The pumps are basically identical, but besides the fuel delivery, the timing advance curve is also slightly different. There are minimum specs when testing on the test stand, not maximum when it comes to fuel pumps at cranking speed. Being a used pump, if anything, it probably pumps a little less at cranking speed than a new pump. The main difference in the fuel delivery between the two pumps is with the engine running and not so much at cranking speed. Too much fuel is not going to be your starting problem. Could it be turned up and getting too much fuel? Jason Z in MO wrote: The Diesel shop checked and the only difference between the 2DH and 1DH is the fuel settings. It does smoke a lot for those few seconds but its cold here. The Diesel shop checked and the only difference between the 2DH and 1DH is the fuel settings. I wasn't able to confirm if it has a 2010 engine so I decided to stick with the same pump. If you recall, this is the pump used on a 2010. something with the advance maybe? This is the DBGVC429-2DH pump which is want came off the tractor. Seems like it dies after the engine speed picks up. I confirmed #1 was at TDC, installed pump with index marks lined up. I used the glow plugs but it constantly would fire up and die. Got a little smoke first then it would fire up but died after about 2-3 seconds. After getting it all back together, bleeding and correcting a couple of fuel leaks I was able to crank it over. Couldn't wait to bolt it all back together so I put my bibs on and set up some lights. I now take the parts book with me for the exact reasons Stan does.I got the pump and injectors back from the pump shop. He kept insisting that I must be mistaken- UNTIL I pointed out that his very own office's website has a specification sheet showing the exact model! he then shook his head and admitted they didn't really know much about their old models and was suprised people still used them. When he couldn't find it in their parts computer, he said I must have the Model number incorrect, because they didn't have a full-size backhoe with that model number. I needed a bucket pin for my Model 50 backhoe attachment. Most of the parts guys there are pretty good and are somewhat familiar with the various models Deere has carried, but one day I had their backup parts/sales guy at the counter. They are the website I hyperlinked on this board that has online original specification sheets posted for many of these machines and attachments. I had a pretty interesting conversation a couple years back with my local JD industrial dealer (Murphy Tractor).
