  Well timing is kind of complicated, in my case anyway. I own a 1986 740 with a D24 Turbo engine as my daily driver. The same engine basically as the non- turbo. The timing procedures are the same. I have the D24 D24T engine rebuild manual on .pdf. It shows at the end of the manual how to time the pump. I will send it to you.
  However, this never worked for me. When I replaced the timing belt, I set the timing to the specified setting but it was too retarded, as there would be a lot of white smoke in all the rpm ranges.
  I did notice when I tore it down for the timing belt replacement, the camshaft was out quite a bit counter clock wise. I had to move it clockwise in order to place the locking plate on the head/camshaft. The injection pump marks was set at the basic setting, that is the bracket and pump marks were lined up. The injection pump was not tilted up or down.
  It appears that there is another way to time these cars. My 1984 Volvo 760GLE‘s engine was timed the same way. Maybe someone can explain it to us as it seems to be a better way. My injection pump is now tilted toward the engine (Advanced) to its maximum.
  It runs really good now, no white smoke; however it will spew out black smoke under a light to heavy load, acceleration. If I am easy on the accelerator, then I don’t see smoke. This tells me my fuel/air mixture is to rich. It didn’t do this prior to the timing belt change. The only time I saw smoke was when I floored it you could see a short burst of black smoke, then none. I did replace the fuel injectors when I did the timing belt change, which may be the cause.
  This car is amazing, you would never know you where driving a diesel as it has the pickup of a gasoline fueled 6 cylinder car. The smilage is truly amazing, even with it running too rich.
  Here a blog that someone has. It does show the timing procedure, however it is too hard to see. http://volvoturbodiesel.blogspot.com/2005/08/how-to-set-your-pump-timing.html
  I hear the non turbo’s are really sluggish, but they are supposed to get better mileage. Just run a good synthetic motor oil. I had a front main seal leaking pretty bad, until I changed the oil to Shell ROTELLA® T Synthetic 5W-40, it stopped about 3 days after and hasn’t leaked since.
