Cummins M11 ISM11 QSM11 Engine Parts Lubricating Oil Filter Head 3406949 3406949X

Basic Information

Part Number: 3406949X

Name: Oil Filter Base (also known as Oil Filter Housing or Oil Filter Mount)

Application: Specifically designed for Cummins engines (e.g., certain models in the QSX, ISX, or N series). Always verify compatibility with your engine model and specification.

Function

The 3406949X Oil Filter Base serves as a critical component in the engine's lubrication system, with primary roles including:

Support and Installation of Oil Filter: Provides a secure mounting point for the oil filter cartridge, ensuring reliable connection between the filter and the engine's oil circuit.

Oil Flow Control: Channels engine oil into the filter for filtration (removing contaminants like metal particles, dust, and sludge) and directs the clean oil back into the engine's lubrication system.

Pressure Regulation: May include built-in pressure relief valves to prevent excessive oil pressure (e.g., when the filter is clogged) and protect the lubrication system from damage.

Sealing and Leak Prevention: Ensures airtight and leak-free connections between the oil filter, engine block, and oil lines to maintain proper oil circulation and system integrity.

Key Features

Material: Typically constructed from high-strength cast iron or aluminum alloy to withstand high oil pressure, temperature, and mechanical stress.

Design:

Precision-engineered threads and sealing surfaces for secure filter installation.

Integrated oil passages (inlet/outlet) to optimize oil flow.

May include mounting brackets or flanges for stable attachment to the engine block.

Compatibility: Designed to fit specific Cummins engine models and corresponding oil filter types (e.g., spin-on or cartridge-style filters). Always confirm the filter model (e.g., Fleetguard®) compatible with this base.

Installation and Maintenance Tips

Installation:

Cleanliness: Ensure the mounting surface on the engine block is free of debris, old gasket residue, or oil stains.

Gasket/Seal Replacement: Always use a new gasket (if applicable) to prevent leaks. Align the base carefully to avoid damaging the gasket or sealing surfaces.

Torque Specification: Tighten the mounting bolts/nuts to the torque value specified in the Cummins service manual (e.g., typically XX N·m; refer to your engine's documentation).

Maintenance:

Regular Inspection: Check for oil leaks around the base and filter during routine maintenance.

Filter Replacement: When changing the oil filter, clean the base's sealing surface and inspect for wear (e.g., cracks, corrosion, or damage to threads).

Pressure Relief Valve Check: If the base includes a pressure relief valve, ensure it functions correctly to prevent overpressure issues.

Replacement Scenarios

Replace the 3406949X Oil Filter Base if:

There is severe corrosion, cracking, or deformation in the base body.

Persistent oil leaks occur due to damaged sealing surfaces (even after replacing gaskets or filters).

The pressure relief valve fails, leading to abnormal oil pressure warnings.

The base's threads are stripped, making it impossible to secure the oil filter properly.

Compatibility Note

This part is a genuine Cummins or OEM (Original Equipment Manufacturer) component. For aftermarket alternatives, ensure they meet Cummins' quality and performance standards.

Always cross-verify the part number (3406949X) with your engine's parts manual to avoid compatibility issues.
