Introduction
The 1964 Ford Thunderbird, particularly the 390FE model, presents unique challenges for modern power steering pump installations. Original equipment may suffer from age-related degradation or may not meet the expectations of performance-oriented restorations. One popular solution, as described in user forums, involves the use of CVF Racing brackets to adapt a GM Saginaw power steering pump to the Ford engine. This article draws exclusively from user experiences shared in online forums and outlines the practical considerations, potential complications, and installation requirements for this modification.
Understanding the Original System and Its Limitations
The 1964 Ford Thunderbird 390FE model was originally equipped with an Eaton power steering pump. While functional for its era, this system has proven problematic for modern restorers. According to forum user reports, the original Eaton pump required multiple rebuilds and continued to leak, albeit without producing noise. This suggests a design or material limitation in the original pump, possibly exacerbated by wear or poor-quality replacement parts.
One user reported replacing the Eaton pump with a "Cardone" (a brand often associated with aftermarket and, in some cases, Chinese-manufactured automotive parts) but encountered repeated failures. The first unit failed after just 20 miles, emitting a loud, high-pitched noise. A second replacement failed after approximately 50 miles under similar conditions. These results highlight the importance of selecting reliable components when undertaking a restoration.
The CVF Racing Solution: Installing a GM Saginaw Pump
Given the shortcomings of the original pump and its unreliable aftermarket replacements, some restorers have turned to the CVF Racing solution: installing a GM Saginaw power steering pump using specially designed brackets. This approach has been described as "absolutely perfect" by one user, who reports no leaks or noise after installation.
Compatibility and Component Adjustments
The installation of a GM Saginaw pump requires several adjustments to ensure compatibility with the 1964 Thunderbird's engine setup:
- Double Crank Pulley: The original 1964 setup cannot be used. A later model double crank pulley must be sourced and installed to accommodate the new pump.
- Fan Belts: The fan belt configuration must be adjusted to account for the new pulley setup. This typically involves acquiring different fan belts that are compatible with the modified drive system.
- Mounting Brackets: The CVF Racing brackets are specifically designed to secure the GM Saginaw pump to the Ford engine block. These brackets must be correctly installed to ensure proper alignment and function.
The user notes that the stock hoses from the original system will fit the new pump, which simplifies the installation process. No modifications to the hydraulic system are required, reducing the complexity and potential for leaks or pressure issues.
Performance and User Experience
After the installation, the user reported that the car "drives like a new Mustang," indicating a significant improvement in steering responsiveness and overall performance. This suggests that the Saginaw pump offers better performance compared to the original Eaton unit, likely due to more modern design and construction.
The absence of leaks and noise further supports the decision to use the CVF Racing brackets and GM Saginaw pump. The user’s satisfaction with the modification underscores the effectiveness of this approach for those seeking a durable and high-performing power steering solution.
Considerations for DIY Installers and Restorers
For those considering this modification, several factors should be taken into account to ensure a successful installation:
- Technical Skill Level: The installation requires a basic understanding of engine components, belt routing, and hydraulic systems. While the process is described as "absolutely perfect" by one user, others may require additional guidance or assistance.
- Sourcing Components: The CVF Racing brackets are the key to this modification. Users must ensure that they obtain genuine parts from a reliable supplier. Additionally, the GM Saginaw pump must be compatible with the Ford's hydraulic system.
- Labor and Time: The installation involves several steps, including removing the original pump, installing the brackets, and adjusting the belt system. The time required will depend on the user's experience and the tools available.
- Cost: While the exact cost is not provided in the source material, the use of specialized brackets and a replacement pump will add to the overall expense. However, the long-term reliability and performance benefits may justify the investment.
Conclusion
The installation of a GM Saginaw power steering pump using CVF Racing brackets represents a viable solution for 1964 Ford Thunderbird 390FE owners seeking improved steering performance and reliability. This modification bypasses the limitations of the original Eaton pump and offers a more durable alternative. The process involves careful component selection, compatibility adjustments, and proper installation to ensure optimal function. For experienced DIY enthusiasts or restorers, this approach can significantly enhance the driving experience of a classic vehicle. However, users should weigh the technical requirements and sourcing challenges before proceeding with the modification.
