It covers topping off fuel, opening the shutoff valve, cracking the injection pump bleeder screw, cranking in stages, then cracking three injectors one at a time until a solid fuel stream appears and the engine runs clean. Best for owners doing this repair themselves.
Appears to be an owner-operator demonstrating their own repair method rather than a professional or dealership tutorial.
Top off the fuel tank, open the shutoff valve, crack the injection pump bleeder screw, crank in stages until a solid fuel stream appears, then crack three injectors and crank again until the engine fires and runs clean.
Only three injectors are cracked using a 17 mil wrench, since injector number four is harder to reach, and that is enough to purge the air.
The video states the Shibaura N844L is the same as a Perkins 404D-22, described as similar.
