2 1/4 diesel how do i adjust the pump

<< < (2/2)

cstokes:
You havn't said whether the smoke is at idle or under load, If it is at idle you may find that the scew gear driven by the cam is worn or the bronze bush it runs on is worn, this causes the diesel pump to retard itself at idle which in turn gives puffs of white smoke. It is well worth checking this first as when i had my old diesel pump calibrated by the specialist after it was fitted it still smoked and then i found out about the scew gear, replaced that and the bush and hay presto smoke resolved.  If however it smokes all the time then this can be either an incorrectly adjusted pump or calibration.  Also antifreeze being burn't in the cylinders can cause white smoking under load which could mean head gasket. Personally i would start with the cost effective options first.

cstokes:
