This kit delivers reliable rotation, reduced friction, and extended service life under demanding driving conditions.

Key Components Included

• Two (2) Radial Wheel Bearings – Precision‑machined to FAG’s stringent tolerances, these bearings provide smooth operation and low noise.
• Two (2) Bearing Seals – Dual sealing ensures protection against dust, moisture, and road debris, maintaining internal lubrication.
• Four (4) Retaining Rings – Secure the bearings within the hub assembly, preventing axial movement during acceleration or braking.
• Two (2) Hub Caps – Protect the bearing faces and provide a finished appearance.
• Installation Tools & Instructions – Includes torque specifications, alignment guides, and recommended procedures for optimal performance.

Technical Specifications

Performance Benefits

The FAG 713 6157 80 kit offers several advantages that enhance vehicle dynamics:

• Reduced Rolling Resistance – Precision engineering minimizes friction, improving fuel efficiency.
• Enhanced Durability – Robust construction and high‑quality seals extend bearing life even under heavy loads or off‑road conditions.
• Consistent Handling – Stable bearings maintain wheel alignment, contributing to predictable steering response.
• Low Noise & Vibration – Tight tolerances and balanced components reduce operational noise.

Installation Procedure

Proper installation is critical for achieving the full benefits of the kit. Follow these steps carefully:

1. Preparation: Remove the wheel, brake assembly, and hub. Clean all surfaces to eliminate debris.
2. Lubrication Check: Verify that the bearings are pre‑lubricated; if not, apply a thin layer of high‑temperature grease.
3. Seal Placement: Insert each bearing seal into its designated position on the hub flange.
4. Bearing Installation: Slide the radial bearing onto the hub shaft, ensuring it sits flush against the retaining ring.
5. Retaining Ring Securing: Place the retaining ring over the bearing and compress it with a calibrated tool to lock the assembly in place.
6. Hub Cap Attachment: Fit the hub cap onto the outer face of the bearing, aligning any mounting holes.
7. Tightening Sequence: Use a torque wrench to tighten all fasteners to the specified values (typically 120 Nm for wheel bolts, 35 Nm for retaining rings).
8. Alignment Verification: Check wheel alignment and adjust if necessary before re‑installing the brake components.
9. Final Inspection: Inspect all parts for proper seating, absence of play, and correct torque.

Maintenance Tips

Even though the kit is pre‑lubricated and sealed, routine checks can prolong its service life:

• Periodic Inspection: Every 10,000 km or annually, inspect seals for signs of wear or leakage.
• Brake System Check: Ensure brake pads and rotors are in good condition to avoid excessive heat that could affect bearing integrity.
• Wheel Alignment: Maintain proper alignment to prevent uneven load distribution on the bearings.
• Avoid Overloading: Do not exceed the specified load capacity, especially when towing or carrying heavy cargo.

Compatibility and Application Notes

The FAG 713 6157 80 kit is specifically engineered for vehicles with a hub diameter of 120 mm and an inner bearing bore of 80 mm. It is commonly found in Mazda models such as the CX‑7, CX‑9, and other front‑wheel platforms that share this geometry. When selecting this kit, confirm the vehicle’s hub specifications to ensure a perfect fit.

Quality Assurance

FAG bearings are manufactured under strict quality control protocols, including:

• Dimensional Accuracy: Each bearing is measured against ISO standards to guarantee consistency.
• Material Testing: Metallurgical analysis ensures the alloy meets hardness and tensile strength requirements.
• Functional Trials: Bearings undergo dynamic testing at various speeds and temperatures before packaging.

Conclusion

The FAG 713 6157 80 Wheel Bearing Kit delivers exceptional performance, reliability, and longevity for front‑wheel applications. Its comprehensive assembly—including bearings, seals, retaining rings, and hub caps—ensures a hassle‑free installation while providing the durability needed for everyday driving and demanding conditions alike.
