Head valves and Crankshaft seals installation in a Yanmar 3JH5EC / Episode 3

The closing episode of a multi-part Yanmar 3JH5EC engine repair series done aboard a sailboat, not a tractor. It walks through front and rear crankshaft seal replacement, head gasket installation with torque procedure, harmonic balancer fitting, and engine reinstallation and RPM calibration. Detailed and hands-on, but entirely marine-focused, tractor shoppers will find nothing applicable here.
