1202-237 – Flange Yokes – 1251 Series – Bolt Circle Dia 3.347″ – Pilot Dia 2.375-M

The 1202-237 Flange Yoke is a crucial component in the 1251 Series, specifically engineered for dependable driveshaft connections. This yoke features a bolt circle diameter of 3.347 inches, which is essential for ensuring a secure fit with the corresponding companion flange. The pilot diameter measures 2.375 inches, allowing for precise alignment and stability during operation.

One of the standout features of the 1202-237 is its four bolt holes, each with a diameter of 0.407 inches. This configuration not only provides ample fastening points but also ensures that the yoke can handle the torque and stresses encountered in various applications. The distance from the centerline of the joint to the flat is 1.625 inches, a dimension that plays a critical role in the overall geometry of the driveline setup.

When selecting a yoke, it’s vital to match the series and dimensions accurately. The 1251 Series yoke is distinct from other series, such as the 1310 or 1350, primarily due to its specific bolt circle and pilot dimensions. Using a yoke that doesn’t match these specs can lead to improper fitment, potential failure, and costly downtime.

• Check the spline engagement depth before installation.
• Ensure proper phasing with the opposite yoke to avoid vibrations.
• Verify that the bolt circle diameter matches your companion flange.
• Inspect the pilot diameter for compatibility with the mating component.

In summary, the 1202-237 Flange Yoke is designed for performance and reliability, making it an essential choice for anyone looking to maintain or upgrade their driveline system.
