Corteco 01026326b Ring

Corteco 01026326B Differential Shaft Seal

The CorTec 01026326B is a high‑performance differential shaft seal designed to provide reliable sealing for the differential input of Ford Transit and related platforms. It is engineered with precision machining and premium materials to ensure long service life under demanding operating conditions.

Key Features

• Material: Premium elastomer core surrounded by a durable metal backing plate for optimal wear resistance.
• Dimensions: Inner diameter 42 mm, outer diameter 75 mm, thickness 11.5 mm – the exact fit for Ford Transit P100 II and similar models.
• Seal Type: Wellendichtring (well‑ended ring) construction that offers excellent sealing against oil leakage while allowing smooth rotation of the shaft.
• Compatibility: Specifically engineered for Ford Transit, P100 II, and other Ford platforms with a 42 mm differential input. It also fits many aftermarket applications requiring the same dimensions.
• Installation: Designed for straightforward installation – replace the old seal without modifying the housing or shaft.

Technical Specifications

Installation Guide

1. Preparation: Remove the old shaft seal by carefully prying it out of the differential housing. Clean the mating surfaces to remove any debris or residual oil.
2. Positioning: Align the new Corteco 01026326B with the shaft, ensuring that the metal backing plate sits flush against the housing wall.
3. Insertion: Gently press the seal into place until it fully seats. Avoid over‑compressing to prevent damage to the elastomer core.
4. Verification: Rotate the shaft manually to confirm smooth movement and that the seal is seated correctly without gaps.
5. Final Check: Inspect for any signs of misalignment or leakage before reassembling the rest of the drivetrain.

Benefits Over Standard Seals

• Enhanced Durability: The metal backing plate protects against wear and tear, extending seal life even under high torque conditions.
• Superior Seal Integrity: Well‑ended design reduces the risk of oil seepage, maintaining optimal differential lubrication.
• Precision Fit: Exact dimensional match eliminates the need for aftermarket adapters or modifications.
• Easy Replacement: Designed for quick swap‑outs, reducing downtime during maintenance.

Applications and Compatibility

The Corteco 01026326B is specifically tailored for the following vehicle platforms:

• Ford Transit P100 II (1991–2000) – 42 mm differential input.
• Ford Transit 1.6, 2.9, and 2.5D variants with matching shaft dimensions.
• Other Ford models that share the same differential housing geometry.

Its universal design also makes it suitable for aftermarket applications where a 42 mm inner diameter seal is required.

Maintenance Tips

• Inspect the seal during routine maintenance to catch early signs of wear or leakage.
• Avoid exposing the seal to extreme temperatures or harsh chemicals that could degrade the elastomer core.
• Use a clean, dry cloth when handling the seal to prevent contamination.

Conclusion

The Corteco 01026326B Differential Shaft Seal delivers reliable performance for Ford Transit and related platforms. Its precise engineering, durable construction, and ease of installation make it a top choice for mechanics and vehicle owners seeking long‑lasting protection against differential oil leakage.
