D2366 Valve Oil Seal for Doosan Engine Parts – Excavator, Truck, Forklift, Loader

Product Details

Product Overview

This high-quality D2366 Valve Oil Seal is a critical component engineered specifically for Doosan diesel engine applications. Designed to regulate oil flow to the valve stem, this seal prevents excessive oil consumption and ensures optimal combustion efficiency. It is a direct replacement part suitable for a wide range of heavy machinery including excavators, trucks, forklifts, bulldozers, buses, and loaders that utilize the Doosan D2366 engine platform.

Manufactured to OEM size specifications, this valve oil seal provides a reliable seal against high-temperature exhaust gases and engine oil, reducing the risk of valve guide wear and carbon buildup. Whether you are a maintenance shop, equipment dealer, or fleet operator, this part offers a cost-effective solution for engine overhauls and top-end repairs.

Key Features & Benefits

• OEM Fitment: Manufactured to exact OEM dimensions for a direct, no-modification installation on Doosan D2366 engines.
• Oil Consumption Control: The precision-molded seal lip effectively minimizes oil leakage into the combustion chamber, reducing blue smoke and lowering oil top-up frequency.
• High-Temperature Resistance: Constructed from durable materials that withstand the extreme heat and pressure found in the valve area of a diesel engine.
• Extended Engine Life: By preventing oil from entering the exhaust tract, this seal helps protect the turbocharger, catalytic converter, and valve guides from premature wear.
• Lowest Price Advantage: Competitive pricing without compromising on quality, ideal for bulk procurement and aftermarket replacement needs.
• Pre-Tested Quality: Each seal undergoes outgoing inspection with a machinery test report provided, ensuring consistent performance.

Technical Specifications

OEM Cross-Reference

This D2366 Valve Oil Seal is a direct replacement for the following Doosan original part numbers and common cross-references. Please verify your specific engine model code to ensure compatibility.

• Doosan / Daewoo: D2366 (Engine Model Code)
• Cross-Reference Notes: While the primary identifier is the engine model D2366, this seal is often used in conjunction with other Doosan valve train components. For exact fitment, compare the seal dimensions (inner diameter, outer diameter, and height) with your original part.

Compatibility

This valve oil seal is commonly used for the following applications. Fitment is inferred based on the engine model and standard industry use. Always consult your equipment’s service manual for verification.

• Engine Models: Doosan D2366 (and related variants)
• Equipment Applications: Excavators, Trucks, Forklifts, Bulldozers, Buses, Loaders, and other heavy machinery powered by the Doosan D2366 diesel engine.
• Note: This part is designed for the cylinder head valve assembly. It is not a universal seal; it is specific to the valve stem diameter used in the D2366 engine.

FAQ

Q1: How do I confirm this D2366 valve oil seal fits my engine?
A: The D2366 is a specific engine model designation. To confirm fitment, check the engine data plate on your Doosan equipment. Ensure the engine model number matches “D2366”. Additionally, measure the inner diameter of your old valve oil seal; it must match the valve stem diameter (typically 7mm, 8mm, or 9mm for this engine family). If you are unsure, contact us with your engine serial number.

Q2: What are the signs that my valve oil seals need replacement?
A: Common symptoms include blue smoke from the exhaust upon start-up or deceleration, increased engine oil consumption, and oil fouling on spark plugs (if applicable). If you notice oil residue in the intake manifold or on the valve stems during a top-end inspection, replacement of the valve oil seals is recommended.

Q3: Can I install this seal without special tools?
A: While it is possible to install valve oil seals by hand, we strongly recommend using a valve seal installation tool or a deep socket to press the seal evenly onto the valve guide. This prevents damage to the seal lip and ensures a proper seat. Always lubricate the seal lip with clean engine oil during installation to prevent dry start tearing.
