Volvo Penta Oil Filter — Part #21549544
This is the genuine OEM full-flow oil filter for Volvo Penta D, TAMD, and MD series marine diesel engines. As the primary oil filter in the engine's lubrication circuit, it filters all engine oil before it reaches critical components — removing contaminants, sludge, and metal particles to protect bearings, journals, and internal surfaces. The spin-on canister design makes replacement straightforward at every oil service. Built to Volvo Penta's original equipment specifications for a direct, no-modification fit.

Parts Desk Insights
Best Use Case: This is the primary oil filter for D, TAMD, and MD series Volvo Penta diesels — the one that every oil change starts with. Replacing it at every service is non-negotiable on these engines. Many of these engines are still working hard at high hours, and clean oil is the single biggest factor in keeping them there.
Common Issues: The most common question is whether 21549544 and 861475 are the same filter — yes, they are the same part under different reference numbers. If your service manual or old filter shows 861475, 21549544 is the correct current replacement. Also note that D/TAMD engines use both a full-flow filter (this part) and a bypass filter — both should be replaced at every oil change. The companion bypass filter is Volvo Penta Oil Filter 21549542.
Service Interval
Replace this oil filter at every engine oil change. Volvo Penta typically recommends oil and filter changes every 250 hours or annually, whichever comes first — refer to your engine's service manual for the exact interval for your model and serial number range. Always replace both the full-flow and bypass filters together at each service.
Technical FAQ
Q: Is this a full-flow or bypass filter?
A: This is the full-flow (primary) oil filter. All engine oil passes through it before reaching engine components. D and TAMD series engines also use a separate bypass filter — see Volvo Penta Oil Filter 21549542 for the companion bypass filter.
Q: Is 861475 the same as 21549544?
A: Yes — 861475 is an alternate Volvo Penta reference number for the same filter. If your service records or old filter show 861475, order 21549544 as the current replacement.
Q: Do I need to replace both the full-flow and bypass filters at every oil change?
A: Yes. Volvo Penta D and TAMD series engines use both filter types, and both should be replaced together at every oil service for complete lubrication system maintenance.
