748GCA Generator case oil filter adaptor

Modernizing an old Knuckle, Pan, or Shovel often means finding a better way to filter your oil. This Paughco oil filter adapter is machined from plain billet aluminum and allows you to run a modern spin-on type filter. It is designed to fit 1936 to 1969 Harley-Davidson models when the stock generator has been removed—typically when running a magneto—and it also fits most custom alternator-generator style crankcases. It is a clean, functional upgrade that provides much better engine protection than the old-school setups, ensuring your vintage iron stays on the road longer with cleaner oil. It is a simple yet effective way to improve the longevity of your classic engine.
