Description
1301-231 is a critical component in the driveline, serving as the connection interface between the axle assembly and the driveshaft. This Companion Flange is specifically designed for Toyota Mid-ship, SQ applications, ensuring a perfect fit with its precise dimensions. The 23 splines with a diameter of 0.990″ are essential for a secure connection, allowing for efficient torque transfer without slippage.
The hub diameter of 1.500″ and pilot diameter of 1.808″ are also vital, as they dictate how well the flange seats onto the differential or transfer case. Mismatched dimensions can lead to vibration issues or even catastrophic failure. The bolt circle diameter of 3.340″ must align perfectly with the mounting points to maintain stability during operation. Any runout in the flange face can introduce unwanted vibrations, so it’s crucial to check that the face is perpendicular to the rotational axis.
- Ensure clean mating surfaces before installation.
- Torque bolts in a star pattern to avoid uneven stress.
- Check face runout after installation to prevent vibrations.
With a through hole of 1.530″ and a face-to-end measurement of 2.234″, the 1301-231 Companion Flange is engineered for reliability and performance. This part is a must-have for any technician working on Toyota Mid-ship, SQ systems, ensuring that your driveline operates smoothly and efficiently.
