O que este vídeo aborda
Jon, owner of the sailboat Antidote, performs a teardown and diagnostic inspection of a 27-horsepower Yanmar 3GM diesel engine to identify the source of an audible internal rattle. After comparing the engine’s performance to a similar unit on SV Narwhal, he uses a mechanic’s stethoscope and a DIY leak-down tester to evaluate cylinder compression and valve health.8:05 The inspection reveals significant wear on the crankshaft keyway, which allows approximately 5 degrees of timing play, and confirms that the pistons have previously struck the valves.17:01 Additionally, the engine’s original motor mounts show severe degradation, with the rubber bond completely separated from the steel base plates.0:56 Jon replaces the failed mounts with Elibogan engine mounts, which feature zinc-plated steel and polyurethane coating for corrosion resistance.2:54 He uses micrometers and a bore gauge to verify that internal clearances remain within the specifications listed in the Yanmar repair manual before sending the components to a machine shop for professional validation.25:49
