for IOE and V Models

Combined gas and oil tanks for F, J and V model series

The right side of the tank contains the fuel, the left side is divided into the reserve fuel tank and the engine oil. The oil compartment also contains the manual pump used to supply additional oil to the crankcase on particularly demanding sections of the route.

Not welded or brazed, "just" soldered

The tanks are soldered using the soft-soldering method, i.e. with lead/tin as the solder. In our days, this process may make you raise an eyebrow, but at least until the 1940s this was just standard. Ernst “Klacks” Leverkus, who is legendary in the German-speaking world, still describes it as an adequate and solid repair method in the 1960s, which, when used correctly by a careful locksmith, can be practiced even far away from any (Harley) workshop. The low melting temperature of soft solder does not put as much strain on the sheet metal and there is also much less distortion.
