Parte zf 1269328289 Synchronizer Ring for Ecosplit Gearbox Genuine Heavy-Duty Transmission Spare

Simple Install Tips

For the best performance and longevity of your Zf 1269328289 Anel Sincronizador, follow these professional installation guidelines:

1. Measure the Wear Limit (O “A” Valor): Before installing, press the new ring onto the gear cone and measure the gap between the ring and the gear teeth using a feeler gauge. If the gap is below the ZF technical limit (usually 0.8mm), the gear cone is worn and must be replaced alongside the ring.

2. Lubrication is Key: Do not install the ring dry. Immerse the 1269328289 in clean transmission fluid (Por exemplo, ZF-Ecofluid M) for at least 15 minutes prior to assembly to ensure the friction material is properly primed.

3. Clean the Mating Taper: Use a specialized cleaner to ensure the gear’s cone surface is free of old oil residue, glazing, or metal particles. A clean surface is required for the friction ring to “grab” properly.

4. Verify Keyway Alignment: During assembly into the synchronizer hub, ensure the three lugs (or notches) on the ring are perfectly centered with the pressure pieces (keys). Misalignment can cause the ring to snap under shifting pressure.

5. Check Sliding Sleeve: Always inspect the internal teeth of the sliding sleeve. If the teeth are rounded or chipped, they will damage your new synchronizer ring almost immediately.
