ZF Transmission Gear 2nd Speed (40 Teeth) – Genuine ZF Spare Part 1272304131

ZF Transmission Gear 2nd Speed (40 Teeth) – Genuine ZF Spare Part 1272304131

Technical Specification

The ZF 2nd Speed Gear (40 Teeth), part number 1272304131, is a vital component engineered for the demanding environments of heavy-duty manual transmissions. Specifically designed for the ZF Ecosplit and related series, this gear is responsible for the critical transition from low-end torque to mid-range cruising speeds.

Simple Install Tip:

• Needle Bearing Replacement: When installing the 2nd speed gear (1272304131), it is highly recommended to replace the associated needle roller bearings. A worn bearing can cause the new gear to misalign, leading to uneven tooth wear.

• Synchronizer Hub Alignment: Ensure the gear is perfectly aligned with the 1st/2nd gear sliding sleeve. Check for smooth engagement by hand before closing the transmission housing.

• Check the Oil Grade: Use only ZF-TE-ML approved lubricants (such as ZF-Ecofluid M). The wrong oil viscosity can lead to “notchy” shifting and increased friction on the gear teeth.

• Torque Settings: Always follow the ZF service manual for the main shaft tightening torques to ensure the gear set is seated with the correct axial clearance.
