CIT WEDI/FIA/PEU

Product Overview

The CIT WEDI/FIA/PEU is a high‑performance differential shaft seal designed for use in a wide range of commercial and passenger vehicles. It is engineered to provide reliable sealing between the differential housing and the driveshaft, preventing lubricant leakage while withstanding harsh operating conditions such as high temperatures, vibration, and exposure to road contaminants.

Key Features

• Durable Construction: Made from premium rubber and reinforced with a steel backing, the seal offers exceptional resistance to wear, tear, and chemical degradation.
• Precision Fit: The seal’s dimensions (32 mm diameter, 50 mm length, 10 mm width) are calibrated to match the original equipment specifications for a variety of models, ensuring a snug fit and optimal performance.
• Broad Compatibility: Suitable for CITROËN, FIAT, LANCIA, PEUGEOT and related models such as the Ducato, Scudo, Boxer, Relay, DS4, and C6. It also fits Peugeot 407, 508, 3008, and 307, as well as Citroën C4, C5, C6, and C8.
• High Temperature Tolerance: Operates effectively up to 200 °C, making it ideal for heavy‑duty applications where heat buildup is a concern.
• Vibration Resistance: Designed to maintain integrity under continuous vibration, a common challenge in commercial vehicle drivetrains.
• Easy Installation: The seal can be installed without the need for special tools or extensive disassembly, reducing downtime and labor costs.

Installation Guide

Installing the CIT WEDI/FIA/PEU seal is straightforward and can be completed in a few simple steps:

1. Remove the Old Seal: Detach the driveshaft from the differential housing. Carefully extract the worn seal using a seal puller or a flathead screwdriver, taking care not to damage the housing.
2. Clean the Housing: Thoroughly clean the differential housing and driveshaft threads with a solvent to remove any residual grease, dirt, or old seal material.
3. Inspect for Damage: Check the housing and driveshaft for cracks or wear. Replace any damaged components before proceeding.
4. Install the New Seal: Slide the new seal onto the driveshaft, ensuring it sits flush against the housing. Align the seal’s mounting flange with the differential opening.
5. Reassemble: Reattach the driveshaft to the differential housing, tightening the mounting bolts to the manufacturer’s torque specifications.
6. Test: After installation, rotate the driveshaft manually to confirm smooth operation and verify that no lubricant leaks from the seal area.

Maintenance Tips

• Inspect the seal periodically for signs of wear or cracking, especially after heavy usage.
• Keep the differential housing clean and free from debris to prevent premature seal failure.
• Use only manufacturer‑approved lubricants that meet the specified viscosity and additive requirements.
• Replace the seal if any leakage is observed, as continued operation with a compromised seal can lead to differential damage.
