Sierra Diesel Oil Filter 18-7884, Replaces Volvo Penta 834337, Fits MD2B, MD6A/B, MD7A/B, 2003, MD17C/D, MD3B Engines

The Sierra 18-7884 is a spin-on diesel oil filter built for Volvo Penta marine diesel engines. It uses high-efficiency filter media that meets or exceeds OE filtration standards, keeping contaminants out of the crankcase to protect bearings, camshafts, and other critical engine surfaces. A built-in anti-drainback valve eliminates dry starts by preventing oil from draining back into the crankcase during engine shutdown, so lubrication is available immediately at the next start.

Construction is steel with an epoxy coating for corrosion resistance, an important feature in the humid, saltwater-exposed marine environment where this filter operates. The canister threads on with a 3/4 inch - 16 NPT connection. The Sierra 18-7884 cross-references directly to Volvo Penta OEM part number 834337 and fits a range of Volvo Penta diesel engines including the MD2B, MD6A/B, MD7A/B, 2003/2003B/2003TB, MD17C/D, and MD3B series. Recommended oil for these engines is 15W-40 meeting VDS-2 or VDS-3 / API CI-4 or higher specifications.
