2 Cylinder Injection Timing

Had some pump work done on my 730D and after putting the pumps back on the tractor and setting the timing according to the marks, it sure is a lot noisier.(ie: diesel knock) It really hammers and I was wondering if any of you guys know if the timing can be retarded or advanced a bit to lessen the noise. I know they are not quiet, I've farmed with them for years, but this seems much louder than before the pump work and I presume it has to do with the timing. I didn't look before taking the pumps off to see where it was set before, so set them by the marks on the flywheel. Thanks. Ted

Ted, first make sure the flywheel is on correctly [the v marks lined up]...While in there put a long wrench on the flywheel nuts to make sure the flywheel is tight [if the flywheel or clutch driver is even close to loose it will hammer pretty good.
~Then make sure the rack timing is THE SAME for both pumps [if they aren't the same, one cylinder will pull harder & knock like crazy]. I like to match them at about the 8 or 10 mark, but they really should match at all settings.
~Did you only have the pumps done or did the injectors get rebuilt also. If the injectors were worked on, make sure the nozzle tips are correct for your pistons.
~I haven't ever tried to retard the injector timing on a 2-cylinder diesel but believe the 730 is 24* BTDC at the production setting. If you do try to retard the timing I wouldn't go much below 20*.
~If you do retard the timing let us know if that quiets it some & if it still starts cold.
~If the injectors weren't worked on it might be a good idea to pull them & turn them around so they are facing forward, then crank the engine to make sure you are getting a good mist spray pattern. CAUTION: don't put hands in front of injectors as those babies have enough pressure to blow diesel fuel through your skin & that is serious.
~If that diesel has been running with dripping injectors or just idled around it might be carboned up & have higher than stock compression, so it wouldn't hurt to run a compression test [a real pain on a diesel]

What rack position & HP on a dyno? The "Knock" if it's a combustion sound is metal ringing from the high pressure shock wave of the flame front. The timimg maybe right on after being too late/soft for years. Metal to metal knocking of course maybe engine internals or the classic two cylinder flywheel or clutch being loose.

Thanks guys. The "knock" is just the classic metal ringing as you stated, flywheel and drive disc etc. are all in good shape. I went through the sequence for timing it again, and checked the rack marks and found that the right side was at 10 when the left was at 8, set them as close as I could see to set them,(tough spot to work in) so it sounds a lot better now. I didn't have the injectors looked at because it was running and starting so well, and still does, but I should have them checked. I kinda figure if it ain't broke, don't fix it! Thanks again. Ted
