<div dir="ltr">Pretty much agreed with Cecil, except, maybe, the 3-5 second rule of thumb. 5 seconds of cranking is actually a LONG time. Think about it: Che-che-che-che-che-che-che-che-che-che-che-che-che-che-che-che-che-che-che-VRoooommm. I'd probably cap it at 2-3 seconds myself. On the other hand, "starts fine" is what Mike M said, so that's probably not an extended cranking period. I guess the issue would be raw diesel fuel washing the oil off the cylinder walls. That's a concern, but I think it would take many years of abusive starting to trash the engine.<div><br></div><div>SO</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Aug 18, 2019 at 6:16 PM Cecil Bearden <<a href="mailto:crbearden@copper.net">crbearden@copper.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">If it fires up quickly without a lot of smoke I would not be concerned. <br>
Many of the newer eastern european tractors will start in near zero <br>
weather without glow plugs. My opinion is that if the tractor will <br>
start easily with 3 to 5 seconds of cranking without a cloud of white <br>
smoke, then the glow plugs were not needed. My D6D Cat states to use <br>
the glow plugs when below 75deg. It does not need them at 75 at all. I <br>
always let it warm up a little before moving also...<br>
