Internal Oil Filler Nut Remover

Specialist internal-style tool designed to remove and install the oil filler retaining nut found on standard generator or alternator stands on Type 1 aircooled engines. This tool is essential for safe, damage-free removal of the internal nut that secures the oil filler assembly.

The oil filler on classic VW engines is mounted to the generator or alternator stand and secured internally with a threaded retaining nut. Because this nut sits inside the filler neck, it cannot be accessed with conventional tools. This dedicated tool engages with the internal surface of the nut, allowing controlled removal without slipping or damaging surrounding components.

Using the correct tool is critical when servicing or replacing oil filler units, breather systems, or generator/alternator stands. Attempting removal without it can result in damaged threads, distorted fittings, or debris entering the engine. This tool ensures precise engagement, making installation and removal straightforward and professional.

Ideal for engine rebuilds, restorations, or maintenance work where the oil filler or stand needs to be removed or replaced.
