What This Part Does
The 423135 is a genuine Volvo Penta OEM spin-on engine oil filter that removes soot, wear particles, and contaminants from the engine oil before it circulates through bearings, cylinder walls, and other precision components. Using the correct OEM filter ensures the filtration specification, bypass valve setting, and thread fit match the original design for the engine. It is the factory-specified oil filter for the Volvo Penta KAD/KAMD 42, 43, 44, and 300 engine group, and is also used across a wider range of legacy Volvo Penta diesel families.
Compatible Applications
Confirm your engine model and serial number before ordering. Volvo Penta used different oil filters across closely related diesel families — do not select by physical size or thread alone.

Serial Number Notice
Oil filter fitment can vary by engine model, production year, filter housing design, and original part number. Always confirm 423135 against your exact engine serial number, the original filter, or the applicable Volvo Penta parts diagram before ordering.
Service Interval
Replace the oil filter at every engine oil change, as specified in the Volvo Penta maintenance schedule for your engine. Also replace if the filter is leaking, overdue, or the engine has undergone major lubrication-system service. Refer to the engine-specific Volvo Penta workshop manual for the correct oil change interval based on operating hours and conditions.
Installation Notes
- Before installation, verify the old filter gasket has not remained stuck to the filter mounting surface — a double-gasketed filter will leak
- Clean the sealing surface and lightly coat the new filter gasket with clean engine oil before installation
- Hand-tighten the filter, then tighten further per the Volvo Penta service specification for the engine — do not over-tighten
- Refill with the correct grade and quantity of engine oil as specified for the engine
- Run the engine and inspect the filter area for leaks before and after the first operating cycle
- Shut down, allow the oil to settle, and recheck the oil level before returning the engine to service

Technical FAQ
Q: Is 423135 a replacement for 4785974?
A: Cross-reference data consistently associates 423135 as the current ordering number for applications that previously used 4785974. However, this relationship is documented in cross-reference catalogs rather than a formal Volvo Penta EPC supersession. Confirm by engine serial number and parts diagram before ordering.
Q: Can I use an aftermarket filter instead of the OEM 423135?
A: Established aftermarket equivalents (MANN W 950/13, Fleetguard LF4017, WIX 92027E) are available for this filter family. However, for marine diesel engines operating in demanding conditions, the OEM filter ensures the correct bypass valve pressure and filtration specification as designed for the engine. Consult your engine service manual for guidance on approved alternatives.
Q: How do I confirm this filter fits my engine?
A: Match by engine model designation, serial number, and the oil filter position in the Volvo Penta parts diagram for your engine. Physical size and thread (1"-12 UNF / ~93mm OD) can be used as a secondary check, but different Volvo Penta diesel families with similar dimensions used different filters with different specifications.
Parts Desk Insights
Best use case: Order 423135 for scheduled oil changes on KAD42 through KAD300, KAMD, and the broader TAMD/TMD/MD diesel families listed above. This is a straightforward maintenance item — keeping an extra filter on board is good practice for liveaboard and extended-cruise applications where a mid-season oil change may be needed away from a well-stocked chandlery.
Common issues: The most frequent mistake is selecting an oil filter by physical size or generic cross-reference without confirming the engine model — Volvo Penta used different filters across diesel families that can look very similar externally. A second common issue is leaving the old filter gasket on the mounting surface when installing the new filter, which causes an immediate oil leak at startup. Always check the sealing surface before threading on the new filter.
