The Yanmar 3D84E-3, 3D84N-2, 3D88E-3, 4D84E-3, and 4D88E-3 are compact 3- and 4-cylinder diesel engines powering the Komatsu PC35R-8 and PC45R-8 mini excavators and the Kobelco SK05J-2 skid steer loader. When an injector fails, you'll experience hard starts, rough running, excessive smoke, misfires, and reduced digging or lifting power.
