The Yanmar 4TNE84 is a compact 4-cylinder diesel engine powering mini excavators, compact track loaders, forklifts, and utility equipment worldwide. When its injection pump fails, you're facing hard starts, severe power loss, excessive smoke, and a machine that can't do its job. This professionally remanufactured injection pump is rebuilt to OEM specifications for the Yanmar 4TNE84 engine family — covering the standard 4TNE84 and the ADCL, G1A, and G2A variants — delivering the same fuel pressure, injection timing, and delivery volume as a new unit at a significantly lower cost.
