FAG SS2506 Engine Crankshaft Seal - Front

Engine Crankshaft Seal for Ford, Mazda, Kia and More

The FAG SS2506 engine crankshaft seal is built for applications that need a precise sealing fit at the crankshaft. It uses a polyacrylate sealing material with a rubber body, spring, and auxiliary lip to help maintain sealing contact and keep engine oil where it belongs.

With dimensions of 1.968 in bore diameter, 1.982 in outside diameter, and 1.457 in width, this seal is sized for specific OE-style applications across Ford, Mazda, Mitsubishi, Kia, Hyundai, Toyota, Chrysler, Dodge, and Plymouth vehicles. The FAG SS2506 is a direct-fit sealing solution for many front and non-position-specific crankshaft seal applications.

Detailed Description

FAG SS2506 is engineered as an OE-style crankshaft seal for engines that require accurate dimensional control and durable sealing performance. The seal construction combines a rubber body with a spring-loaded sealing edge and auxiliary lip to help maintain contact under operating conditions. Its polyacrylate sealing material is selected for demanding engine environments where heat and oil exposure are common.

This part cross-references Dorman - HELP 14671 and National 223750 for the same application. It is used across a wide range of vehicles, including Ford Transit Connect, Ford Edge, Ford Fusion, Mazda CX-9, Mazda 3, Kia Optima, and Toyota Tacoma applications listed in the fitment data. If you are replacing a crankshaft seal on a Ford Fusion front application or a Mazda 6 engine seal, SS2506 is built to match the specified dimensions and sealing profile.

What It Helps Address

• Engine oil leakage at the crankshaft seal area
• Contamination from dirt, dust, and moisture entering the seal zone
• Loss of grease or lubricant retention at the bearing/seal interface
• Wear-related sealing issues on high-mileage engines
• Replacement needs for front crankshaft seal service on listed vehicles

Installation Notes and Tips

Verify the bore diameter, outside diameter, and width against the removed seal before installation. Clean the sealing surface thoroughly and inspect the crankshaft and housing for scoring, corrosion, or debris that could affect sealing. Confirm the exact engine configuration and position, since the fitment list includes both front and N/A applications across multiple makes and models. For vehicles such as Ford Edge, Mazda 3, and Mitsubishi Eclipse, match the application notes in the fitment data before ordering.

Quality Assurance

FAG designs seals to meet vehicle manufacturer specifications and works with suppliers to maintain its quality standards. The SS2506 is built for demanding sealing requirements and application-specific fitment across a broad range of import and domestic vehicles.
