Mitsubishi OEM Oil Pump Assembly Evo X 1211A035

Firstly, Buy Mitsubishi OEM Oil Pump Assembly Evo X 1211A035 online. The Mitsubishi OEM Oil Pump Assembly Evo X 1211A035 is a genuine Mitsubishi factory replacement engine oil pump designed for the Mitsubishi Lancer Evolution X 4B11T. The oil pump is a critical component of the engine lubrication system because it circulates engine oil through the lubrication passages that protect internal components during operation. Mitsubishi parts diagrams identify 1211A035 as the oil pump assembly under diagram reference 04000A.

For Evo X owners rebuilding a 4B11T engine, replacing a worn oil pump, restoring an engine, or maintaining a factory-spec lubrication system, the genuine Mitsubishi 1211A035 provides a direct OEM replacement for the original oil pump assembly. Current OEM parts listings identify the assembly for 2008–2015 Mitsubishi Lancer Evolution X applications.

Mitsubishi OEM Oil Pump Assembly Evo X 1211A035

The Mitsubishi OEM Oil Pump Assembly Evo X 1211A035 is manufactured for the Evo X 4B11T engine and is sold as a complete oil pump assembly. It is different from the individual oil-pump chain, chain guide, tensioner, sprocket, and mounting bolts that make up the surrounding lubrication-system components. Mitsubishi’s parts diagram lists these components separately.

This makes 1211A035 an important part to identify correctly when performing a 4B11T engine rebuild or lubrication-system repair.

Genuine Mitsubishi OEM Replacement

Using a genuine Mitsubishi oil pump is particularly important when rebuilding an Evo X engine where maintaining the factory lubrication-system configuration is a priority.

The oil pump operates continuously whenever the engine is running. It draws engine oil from the oil pan and supplies pressurized oil to the engine’s lubrication passages. Proper oil circulation is essential for protecting bearings, the crankshaft, camshafts, turbocharger lubrication system, and other internally lubricated components.

The OEM 1211A035 is designed specifically around the Evo X application rather than being a universal replacement pump.

Designed for the Evo X 4B11T

The 4B11T turbocharged engine used in the Evolution X places significant demands on its lubrication system. The engine uses pressurized engine oil throughout its internal lubrication circuit, making the oil pump an essential component of overall engine reliability.

OEM parts references identify 1211A035 as the Evo X oil pump assembly, with applications covering the 2008–2015 Mitsubishi Lancer Evolution X.

Whether you’re refreshing a stock 4B11T or rebuilding an engine for a performance project, the correct oil pump should be selected according to the exact engine and vehicle application.

What Does the Evo X Oil Pump Do?

The oil pump’s primary job is to circulate engine oil through the lubrication system.

Engine oil must reach numerous moving components quickly after startup and continue circulating while the engine is running. The lubrication system helps reduce friction, carry away heat, and protect internal engine components from excessive wear.

The oil pump therefore plays a fundamental role in maintaining the engine’s oil supply and pressure.

A problem with the pump or another component of the lubrication system can result in insufficient oil circulation. Because oil pressure problems can lead to serious engine damage, unusual oil-pressure readings, warning lights, or unexplained pump noise should be investigated promptly.

Complete Oil Pump Assembly

The 1211A035 is the oil pump assembly itself. It should not be confused with the other components that drive and support the pump.

The Mitsubishi parts diagram separately identifies:

• 1211A035 — Oil Pump Assembly
• MN183896 — Oil Pump Chain
• MN183897 — Oil Pump Chain Guide
• MN183898 — Oil Pump Chain Tensioner
• MN183899 — Oil Pump Sprocket
• MF140225 — Oil Pump Sprocket Bolt
• MN187028 — Oil Pump Chain Tensioner Bolt
• 1050A063 — Oil Pump Bolts

These components work together as part of the Evo X engine’s lubrication and oil-pump drive system.

Firstly, Secondly, Thirdly — Why Choose OEM 1211A035?

Firstly, the Mitsubishi OEM 1211A035 is specifically designed for the Evo X 4B11T engine application.

Secondly, replacing a worn or questionable oil pump can be an important part of a comprehensive engine rebuild or lubrication-system service.

Thirdly, choosing a genuine Mitsubishi component helps maintain the factory oil-pump configuration and compatibility with the surrounding OEM components.

When Should the Oil Pump Be Replaced?

Oil pump replacement may be appropriate during a major engine rebuild or when inspection indicates that the original pump is worn or damaged.

Possible reasons for replacement include:

• Low or abnormal engine oil pressure
• Excessive oil-pump noise
• Oil-pressure warning conditions
• Internal pump wear
• Engine rebuild or overhaul
• Damage to the original pump
• Preventative replacement during a comprehensive build
• Restoration of a high-mileage Evo X engine

However, low oil pressure does not automatically mean that the oil pump is the problem. Oil viscosity, oil level, bearings, clearances, seals, the pickup system, oil passages, and other lubrication components can all affect oil pressure.

A proper diagnosis should therefore be completed before replacing the pump.

Oil Pump and Engine Rebuilds

The Mitsubishi OEM Oil Pump Assembly Evo X 1211A035 is particularly relevant when rebuilding a 4B11T.

During an engine rebuild, the lubrication system should be inspected as a complete system rather than focusing only on the pump. The oil pickup, oil pan, pump drive components, chain, sprocket, tensioner, and lubrication passages should be checked for contamination, damage, or abnormal wear.

If an engine has experienced catastrophic internal failure, the oil pump and lubrication system should receive additional attention because metallic debris can circulate through the engine and potentially affect replacement components.

Important Fitment Information

Current OEM listings identify 1211A035 for the 2008–2015 Mitsubishi Lancer Evolution X, while Mitsubishi parts diagrams list it throughout the Evo X oil-pump assembly application.

This part should not automatically be assumed to fit every Mitsubishi vehicle using a 4B11 engine. The Evo X 4B11T has application-specific components, and naturally aspirated Lancer models can use different oil-pump part numbers. Always verify the exact part number against the vehicle and engine before ordering.

Installation Considerations

Installation of the oil pump should be performed as part of a proper engine service or rebuild.

The mating surfaces should be clean, the pump drive components should be inspected, and the applicable Mitsubishi assembly procedures should be followed. The oil pump chain and related components should also be inspected before installation.

After installation, the lubrication system should be properly primed before the engine is operated. This is especially important on a newly rebuilt engine or when the oil pump has been replaced.
