The provided source material details installation and maintenance procedures for Moog universal joints and provides information regarding several Moog servovalve series. Proper installation and maintenance are key to ensuring reliable and extended service life of Moog universal joints. This article will focus on the installation and maintenance of Moog universal joints, drawing exclusively from the provided documentation. Information regarding servovalve installation, operation, and troubleshooting will be noted where present in the source material, but will not be the primary focus.
Universal Joint Installation – Pre-Installation Steps
According to the provided documentation, before installing a Moog universal joint, three steps should be followed to ensure longevity. The specific nature of these three steps is not detailed within the provided source material. However, the documentation emphasizes the importance of adhering to proper installation procedures for optimal performance and service life.
Universal Joint Installation – Grease Considerations
A critical aspect of Moog universal joint installation is lubrication. New Moog universal joints are shipped with a limited amount of grease, sufficient only to hold the needles in place during the assembly process. This initial grease quantity is not adequate for operational lubrication. Therefore, it is essential to apply additional grease during installation.
The documentation specifies that grease should be applied until clean, fresh grease extrudes from all four cup seals. This ensures that all internal components are adequately lubricated, reducing friction and wear.
Grease Fitting Locations
Moog universal joints are available with varying grease fitting configurations. These configurations include:
- Grease fittings located in the body of the joint.
- Grease fittings located in the caps of the joint.
- Standard grease fittings.
- Flush-type grease fittings.
When flush-type fittings are used, the documentation recommends utilizing a needle nozzle to facilitate grease application. The documentation includes photographic examples (Photos 3 and 4) illustrating standard and flush-type grease fittings.
Maintenance Recommendations
Proper maintenance is crucial for maximizing the lifespan of Moog universal joints. The documentation highlights the importance of following helpful maintenance tips, though the specific details of these tips are not fully elaborated upon in the provided source material. Regular maintenance contributes to reliable operation and extends the overall service life of the components.
Moog Servovalve Information
While the primary focus of the provided documentation centers on universal joints, information regarding Moog servovalves is also present. The documentation references several Moog servovalve series, including:
- Series 79 Industrial Servovalve
- G631/631 Series Industrial Servovalve
- G631K/D631K series intrinsic safety protected Industrial Servovalve
- G771/G772/G773 (simplified as G77X) and 771/772/773 (simplified as 77X) Electrohydraulic Industrial Servovalve
- Jet Pipe intrinsic safety protected Industrial Servo Valve
For each of these servovalve series, the documentation states that manuals are available providing instructions and procedures necessary for installation, operation, and troubleshooting. These manuals cover topics such as installation and mounting notes, connections, and specifications. The documentation also references “Installations, Technical Data, Connections” as content covered within these manuals.
Additional Considerations
The documentation emphasizes that Moog universal joints are designed to meet stringent Original Equipment (OE) standards and overcome real-world challenges. However, achieving optimal performance and longevity relies heavily on adhering to proper installation and maintenance procedures. The documentation provides photographic examples (Photos 1 and 2) that are referenced in the installation procedure, but the images themselves are not included in the provided source material.
Conclusion
The provided documentation highlights the importance of correct installation and ongoing maintenance for Moog universal joints. Key takeaways include the necessity of adequate lubrication during installation – applying grease until it extrudes from all cup seals – and awareness of the different grease fitting configurations available. While information regarding Moog servovalves is also present, the documentation primarily focuses on ensuring the reliable and extended service life of Moog universal joints through proper procedures. The documentation stresses that following these procedures is essential for meeting OE standards and addressing real-world operating conditions.
