I have a 1964 Ford 4000D with a 170 cid 4 cylinder diesel. It is naturally aspirated. I did some resetting of the timing a while back to factory specs and it helped the tractor greatly. Much less blue smoke, which used to be commonplace.<br>Now it seems like it is smoking a little more than it used to. I'm thinking I should advance the timing some more but I don't know how much to do it.<br>I know with a gas engine you just advance it a ways and then see if it pings during accelleration, and if it does, retard the timing a little.<br><br>What do I look for/listen for on a diesel when playing with the timing?<br><br>Thanks,<br>Chris

If you advance it too far it will sound like a hammer trying to get out of the exhaust manifold.<br> Danny

Like Chris said, someone on the YTMAG Ford Board will answer just about anything you might need to know for Ford tractors. Several members here hang out over there - CTDs, old tractors - might be contagious.

Yeah, thanks for reminding me. I was on YT's forums before this place existed. ;D<br>I posted there also.<br>I will try out the ideas you and replies on YT give me over this weekend.<br><br>Thanks,<br>Chris<br>

How about playing with the timing on an 03 John Deere 990 I-4 diesel?

Maybe you do it like I did after rebuilding the engine in my 870 Case. ???<br><br>Put the pump on, try and line the bolt holes up with the marks in the paint?? ;D ;D<br><br>Runs good, starts good. Mus t be pretty close! ;D<br><br>One of these days I should have someone with the proper tools check it I guess. [undecided]

Tool,<br>I actually have a procedure to follow in my Ford 400 manual, and can find the necessary marks to verify against.<br>Another problem I have had is turing the injector pump since it has solid lines running into it. This is a brute forse kind of thing and I worry about breaking something, cracking a line, etc.<br>I will be taking another whack at it this week or weekend.<br><br>Chris
