Replace connecting rods and bearings yourself?

The continuous use of roller bearings in the connecting rod big end of Harley-Davidson air-cooled engines since 1915 ensures that the bearings require comparatively little oil and, above all, less oil pressure than a plain bearing. It also makes it easy to replace individual components, but requires the crankshaft to be dismantled. Depending on the condition of the components, it is possible to replace only individual parts and this can be done in a well-equipped workshop. The screw connections using tapered ground journals make this possible. The crankshaft must be centered after replacing the connecting rods and connecting rod bearings.
