★ Professional repair kit for overhauling and converting original starter motors. High-quality components for a reliable 12 volt conversion.
Application
This kit is suitable for overhauling Autolite starter motors type MZ-4113 and MZ-4199, as fitted to vehicles being converted from original 6 volt to 12 volt. The field coil is the heart of the starter motor and generates the necessary magnetic field.
Installation notes
Installation of field coil windings requires some technical knowledge. The positive brushes must be soldered. Ensure correct insulation between the field coil and starter motor housing. After installation, test all electrical connections and check that the field coil does not rub against the armature.
Compatibility
Specific for 12 volt systems. NOT suitable for original 6 volt configurations – use a 6V repair kit for that purpose. Note: when converting to 12V, the entire electrical system (battery, voltage regulator, ignition coil, lamps) must also be converted to 12V.
Historical context
The Autolite MZ-4113 starter motor was the standard 6 volt starter motor in WWII Willys MB and Ford GPW jeeps. After the war, many owners switched to 12 volt systems due to better availability and reliability, making these conversion kits essential.
