Pieza original ZF. 1250304391 Synchronizer Ring for Manual Transmissions | Proveedor de piezas OEM ZF

In the world of heavy-duty transmissions, the 3rd and 4th gear transition is the most frequently cycled range. If your gearbox is struggling to stay in gear or experiencing “notchy” shifting, the synchronizer hub is often the root cause. El ZF 1250304396 Centro sincronizador is the central component that holds the sliding sleeve and synchronizer rings, acting as the mechanical heart of the shifting process.

As a specialized Distribuidor de piezas ZF, we’ve seen the damage caused by low-quality aftermarket hubs—they often suffer from micro-cracks or spline failure under high torque. This genuine pieza ZF is forged from high-tensile steel and machined to zero-tolerance specifications. Choosing an authorized Proveedor de piezas ZF ensures that the internal splines perfectly match your main shaft, preventing the vibration and wear that leads to catastrophic gearbox failure.

Consejo de instalación simple:

1. Check for Directionality: Many ZF hubs are not symmetrical. Look for a small notch or a stamped “arrow” on one side of the 1250304396 hub. Installing it backward will cause the sliding sleeve to bind and may prevent the gearbox from engaging 4th gear entirely.

2. Inspect the Internal Splines: Before sliding the hub onto the main shaft, check the shaft splines for any “stepping” or burrs. A new hub on a damaged shaft will eventually develop play, leading to gear pop-out.

3. Pressure Plate & Ballestas: When rebuilding the hub assembly, always use new synchronizer springs and pressure plates (dogs). Reusing old, weakened springs can lead to poor synchronization even with a brand-new hub.

4. The Snap-Ring Seat: Ensure the snap ring is fully seated in its groove after the hub is pressed on. Use a brass drift to gently tap the hub to ensure it is bottomed out before locking it in place.
