What This Filter Does

The 861473 is the OEM spin-on engine oil filter for selected Volvo Penta D1 and MD-series compact marine diesel engines. It removes wear particles, dirt, and other contaminants from the engine oil before they can circulate through bearings, journals, and other precision internal components. Volvo Penta’s own maintenance catalog specifies 861473 directly for the D1-13, D1-20, MD2010, and MD2020 engine families.

Note: This filter is specific to the compact D1/MD-series engines listed below. Larger D1 and D2 engines typically use a different filter — confirm by engine model and serial number before ordering.

Compatible Applications

• Volvo Penta D1-13
• Volvo Penta D1-13B
• Volvo Penta D1-13F
• Volvo Penta D1-20
• Volvo Penta D1-20B
• Volvo Penta D1-20F
• Volvo Penta MD2010

• Volvo Penta MD2010-D
• Volvo Penta MD2020
• Volvo Penta MD2020-B
• Volvo Penta MD2020-C
• Volvo Penta MD2020-D

Confirm by engine model and serial number. Do not assume fitment extends to D1-30 or larger D2 engines — those use a different oil filter (3840525).

Serial Number Fitment Notice

Use your engine model and serial number to confirm 861473 is specified for your exact engine configuration. Similar compact diesel engines in the Volvo Penta range use different oil filters, so matching by model — not thread size or dimensions alone — is essential.

Service Interval

Replace the oil filter at every scheduled engine oil change per the Volvo Penta maintenance schedule for your engine model. For D1 and MD-series engines, oil and filter changes are typically required annually or at the specified hour interval, whichever comes first. Always replace the filter at every oil change — never reuse the old filter when changing oil.

When to Replace

• At every scheduled engine oil change
• Whenever the engine oil is drained or replaced
• If the filter canister is damaged, cracked, or heavily corroded
• After internal engine contamination or major lubrication-system service
• When the service history is unknown

Installation Notes

Follow the Volvo Penta maintenance procedure for your engine when changing the oil filter:

• Drain the engine oil and confirm the old filter gasket has been fully removed from the mounting surface
• Clean the filter mounting surface
• Lightly coat the new filter’s rubber gasket with clean engine oil before installation
• Install by hand until the gasket contacts the mounting surface, then tighten per the Volvo Penta specification — do not overtighten
• Refill with the correct grade and quantity of engine oil specified for your engine
• Start the engine and inspect the filter area carefully for leaks
• Shut down and recheck oil level before returning to service

Technical FAQ

Q: Does 861473 fit D1-30 or D2-series engines?
A: No. The D1-30 and larger D2 engines use a different Volvo Penta oil filter (3840525). The 861473 is specifically confirmed for D1-13, D1-20, MD2010, and MD2020 engines. Always confirm by engine model and serial number.

Q: What earlier numbers does 861473 replace?
A: Volvo Penta 861473 supersedes earlier numbers 861826 and 3808605 in the same application.

Q: Is Sierra 18-7960 a compatible aftermarket alternative?
A: Sierra 18-7960 is documented as an aftermarket cross-reference for this filter. Confirm against your engine model before ordering any aftermarket replacement.

Q: Can I reuse the filter if the oil looks clean?
A: No. The filter contains accumulated contaminants regardless of how the oil looks, and the internal bypass valve and filter media degrade with service. Replace at every oil change.

Parts Desk Insights

The most common issue with this filter is customers ordering it for a D1-30 or D2 engine based on the fact that it’s a Volvo Penta D-series diesel filter. The 861473 is specifically for the compact D1-13, D1-20, MD2010, and MD2020 families — the larger D1 and D2 engines use a different filter. Confirming the engine model before ordering saves an unnecessary return. The other thing worth mentioning to customers is the old gasket check — double-gasketing a spin-on filter (leaving the old gasket on the block and torquing a new one on top) is one of the most common causes of an oil leak immediately after a filter change.
