I have a 82 240 with the D-24 diesel engine, and have just discovered that the injection pump front seal is leaking signifigantly. I have a fair amount of experince with gasser volvo, and with other types of diesel engines, but not with these particular engines. So, I have come here. First of all, can you just replace the fropnt seal on the injection pump, or would it require the pump to be torn down? If I can't replace the seal, any recomendation on where to get a good used pump? I do not really want to fork out the $$$ for a rebuilt or new unit. The current one seems to work just fine, except for that leak. Also, how hard is it to remove and properly replace the pump? I have a service manual, but it calls for a number of tool which I do not have. Has anyone had expoerince doing the job without the special tools? Also, if I get a 740 (turbed) pump, is there a way to turn the fuel down so it does not overfuel? Will the boost pressure sensor thing work to that extent? (that is, if it's not conected, for the equivilent of no boost, will the full throttle injection amount still be the same as a na engine??) Baring that, is there an easy ajustment on the fuel limiter? I have a fdair amount of experince with the IH diesels in 80's ford pickups, and on those engines, there is a fuel limiting screw that's pretty easy to adjust, and it's pretty easy to adjust it to where you just start to get black smoke under full throttle.
