Filter Replacement For Twin Disc MG-5090A Marine Gear

April 3, 2025

Oil filters keep particles from damaging the clutch packs and gears. Replace the filter every 1,000 hours or annually.


  1. Locate the spin-on filter—typically near the top of the housing.
  2. Use an oil filter wrench to remove the filter.
  3. Clean the sealing surface on the housing.
  4. Install the new filter and hand-tighten until the gasket contacts, then tighten an additional ¾ turn.
  5. Start the engine and verify there are no leaks.

Diesel Pro Power offers aftermarket filter elements compatible with the MG-5090A.
