Injection pump leak, Komatsu PC180-LC3 Kiki Pump

I've developed a leak where the plunger assembly meets the block as circled in the picture, Do you guys think this can be a field fix or should I pull the pump and have it rebuilt?

    It’s definitely a field fix.. Pull the side cover and bump the engine until the cylinder in question is at the BOTTOM OF THE STROKE.. Remove the delivery valve holder and replace the oring AND delivery valve gasket.. Lube the oring and torque to 30-35 ftlbs.. Good luck

    Bosh pump parts will fit if you're in a bind trying to find Kiki parts.
