Black smoke is usually a symptom of a clogged or worn injector. When the 719255-53100 injector nozzle fails to atomize diesel correctly, it leads to incomplete combustion. Replacing with a new 71925553100 assembly restores the power curve and reduces emissions immediately.
For engine overhaul projects involving the 4TNE84 or 4TNE88, we recommend testing all injectors. If one 719255-53100 is faulty, others likely have similar wear. A full set replacement ensures balanced cylinder pressure and prevents crankshaft vibrations.
Installation should follow the Yanmar service manual. Typically, clean the seat thoroughly, use a new copper washer, and tighten to specified torque. Overtightening can crack the nozzle body.
