ZF Gear 3rd Speed (37 Teeth) for Heavy-Duty Transmissions – Genuine Part 1272304134

ZF Gear 3rd Speed (37 Teeth) for Heavy-Duty Transmissions – Genuine Part 1272304134

Technical Specification

The ZF 3rd Speed Gear (37 Teeth), part number 1272304134, is a high-performance transmission component designed for heavy-duty commercial vehicles. As a core element of the ZF Ecosplit and Ecomid gearbox series, this 37-tooth gear is specifically engineered to handle the intermediate torque demands required for efficient load-pulling and smooth acceleration.

Simple Install Tip:

• Ratio Matching: Ensure you are replacing like-for-like. This is the 37-tooth version of the 3rd speed gear; verify it matches the gear count on the countershaft to avoid transmission noise or damage.

• Synchronizer Ring Clearance: Always check the “K-measure” (clearance) between the gear and the synchronizer ring during installation. If the clearance is below the ZF service limit, replace the synchronizer ring alongside the 1272304134 gear.

• Snap Ring Inspection: When securing the gear on the shaft, always use a new snap ring/circlip. Reusing old rings can lead to axial movement and catastrophic gear failure.

• Heat Application: If a press fit is required, use a regulated induction heater. Avoid using open flames to heat the gear, as this can destroy the specialized heat treatment of the steel.
