Yanmar 4jh5e Diesel Pump

My Yanmar 4jh5e vibrates too much. When I lose the fuel line to piston #3, the vibration reduces. The engine pistons holds its pressure steady. I swap the injectors but the problem stayed. Recommendations?

Re: Yanmar 4jh5e Diesel Pump

does the vibration reduce in high rpm?
check your no3 injector maybe is stuck and opens on low pressure causing preignition
