FAQ

Q: Is this oil filter seat a direct fit for my NT855 marine engine?
A: Yes, part number 204163 is the OEM specification for the NT855 and M11 series. It should directly replace the original seat without modifications. However, we recommend verifying your engine’s serial number against parts documentation to confirm compatibility, as minor design changes may have occurred over production years.

Q: Can I install this part myself, or do I need a professional mechanic?
A: Installation is straightforward for a qualified diesel mechanic. The process involves removing the old filter seat, cleaning the mounting surface, applying a new gasket (sold separately), and torquing the bolts to factory specifications (typically 40-50 ft-lbs for the NT855). We always recommend consulting your engine’s service manual for exact procedures and torque values.

Q: How often should the oil filter seat be replaced?
A: The oil filter seat itself is a durable, long-life component and typically only requires replacement if it becomes damaged (cracked, warped, stripped threads) or develops a leak. During routine oil changes, inspect the seat and gasket for signs of wear. If you notice oil weeping from the filter base, replacement of both the seat and gasket is advised to prevent contamination of the lubrication system.
