OEM 21350-2B000 COVER ASSY-TIMING CHAIN & OIL PUMP / 213502B000 For Select HYUNDAI KIA Models

A timing chain cover assembly is a protective housing located at the front of the engine block. It covers and encloses the timing chain, which connects the crankshaft and camshaft(s) in an engine. The timing chain cover assembly is typically made of durable materials such as aluminum or cast iron.

• Cover Plate: The cover plate is the main section of the assembly that encloses the timing chain and related components. It is bolted to the engine block and provides a protective barrier against debris, dust, and moisture.
• Gasket: A gasket is placed between the timing chain cover assembly and the engine block to create a reliable seal and prevent oil leaks. The gasket ensures that the lubricating oil inside the engine remains contained within the system.
• Timing Chain Tensioner: The timing chain tensioner, located within the timing chain cover assembly, applies tension to the timing chain. It helps maintain the proper tension and alignment of the timing chain, ensuring precise timing between the crankshaft and camshaft(s).
• Timing Marks: The timing chain cover assembly often features timing marks or indicators that help align the timing chain and set the correct timing for the engine's operation. These marks assist in synchronizing the movement of the crankshaft and camshaft(s) for optimal combustion and engine performance.
• Oil Seal: A timing chain cover assembly may include an oil seal to prevent oil leakage from the front of the engine. The oil seal ensures that lubricating oil used within the engine remains contained and does not escape through the timing chain cover assembly.
• Access Points: The timing chain cover assembly may have access points or openings for components such as the water pump, oil pump, and crankshaft sensor. These access points allow for easy installation, maintenance, and replacement of these components without removing the entire timing chain cover assembly.

A timing chain cover assembly is essential for proper engine operation and is constructed of strong, durable materials to ensure a long service life. Proper maintenance and regular inspection of this assembly is important to ensure it is functioning properly and helping your engine run smoothly.

Integrated Timing Chain Guides: Many timing chain cover assemblies include built-in guides or rails that help guide and support the timing chain. These guides prevent excessive movement and maintain proper alignment of the timing chain, reducing the risk of chain slippage or damage.

Tensioner Mounting Provision: Timing chain cover assemblies often have a provision for mounting the timing chain tensioner. This feature allows for easy installation and adjustment of the timing chain tensioner, ensuring proper tension and alignment of the timing chain.

Accessory Mounting Points: Timing chain cover assemblies may include mounting points or provisions for attaching various engine accessories such as the water pump, oil pump, alternator, or power steering pump. These mounting points provide a convenient and secure attachment for these components.

Oil Passage Openings: Timing chain cover assemblies typically have oil passage openings that allow for the flow of lubricating oil to specific engine components. These openings ensure proper lubrication of the timing chain, camshaft(s), and other related components.

Timing Marks: Many timing chain cover assemblies feature timing marks or indicators that assist in setting the correct timing for the engine. These marks help align the timing chain with the camshaft(s) and crankshaft, ensuring precise valve timing and optimal engine performance.

Reinforced Construction: Timing chain cover assemblies are often designed with reinforced construction to withstand the forces and vibrations within the engine. This enhances durability and helps prevent warping or damage to the timing chain cover assembly.

Sealing Features: Timing chain cover assemblies incorporate sealing features such as gaskets or O-rings to create a reliable seal between the cover assembly and the engine block. These seals prevent oil leaks and maintain proper oil pressure within the engine.

Removable Covers: Some timing chain cover assemblies feature removable covers or access panels that allow for easy inspection, maintenance, or replacement of the timing chain or other components without the need to remove the entire assembly.

Compatibility with Engine Components: Timing chain cover assemblies are designed to be compatible with specific engine models and components. They are engineered to fit properly and provide the necessary clearance for the timing chain, tensioner, and other related parts.

Material: Timing chain cover assemblies are typically made from durable materials such as cast aluminum or cast iron. The material choice depends on factors such as engine design, operating conditions, and weight considerations.

Dimensions: Timing chain cover assemblies come in various sizes and shapes to fit different engine configurations. The dimensions include length, width, and height, which should match the engine's requirements and provide proper clearance for internal components.

Mounting Type: Timing chain cover assemblies can have different mounting types, such as bolt-on or stud-mounted. The mounting type should be compatible with the engine block and provide secure attachment for the cover assembly.

Sealing: Timing chain cover assemblies incorporate sealing features to ensure a reliable seal between the cover assembly and the engine block. This helps prevent oil leaks and maintain proper oil pressure. The sealing method can include gaskets, O-rings, or integrated sealing designs.

Oil Passage Design: Timing chain cover assemblies feature oil passages that allow for the flow of lubricating oil to specific engine components. The design of these oil passages, including their size, shape, and positioning, should be optimized to ensure proper lubrication and oil flow within the engine.

Timing Chain Guide Provision: Many timing chain cover assemblies include provisions for mounting timing chain guides. These provisions should be designed to securely hold the timing chain guides in place, preventing excessive movement and maintaining proper alignment of the timing chain.

Tensioner Mounting Provision: Timing chain cover assemblies often have a provision for mounting the timing chain tensioner. The design of this provision should allow for easy installation, adjustment, and proper positioning of the tensioner to maintain the correct tension of the timing chain.

Timing Marks: Timing chain cover assemblies may feature timing marks or indicators that assist in setting the correct timing for the engine. These marks should be accurately positioned and clearly visible to facilitate proper timing alignment during engine assembly or maintenance.

Compatibility: Timing chain cover assemblies need to be compatible with the specific engine model and manufacturer's specifications. This includes compatibility with other engine components such as the crankshaft, camshaft(s), and timing chain itself.
