ZF Part 1269304137 Synchronizer Cone for Heavy-Duty Transmissions | Genuine Gearbox Spare


Technical Specification

The ZF Synchronizer Cone 1269304137 is a critical component designed to facilitate smooth and precise gear transitions in heavy-duty manual transmissions. As a core element of the synchronizer assembly, this cone utilizes a high-performance friction lining (often Molybdenum or Carbon-based) to equalize the speeds of the gear and the shaft during shifting.

Simple Install Tips 

Proper installation of the ZF 1269304137 Synchronizer Cone is vital for gearbox health. Follow these expert tips:

  1. Check Friction Surfaces: Before installation, inspect the mating synchronizer ring and gear taper. If there are signs of scoring or blueing (overheating), replace the mating components along with the cone.

  2. Cleanliness is Crucial: Use a lint-free cloth and specialized brake cleaner to remove any anti-corrosion oil from the new cone before installation. Contaminants can reduce the friction coefficient and cause shifting issues.

  3. Pre-Lubrication: Dip the synchronizer cone in the specific transmission fluid (approved ZF-TE-ML oil) before assembly. Never install a synchronizer cone “dry.”

  4. Measure Clearance: Use a feeler gauge to check the “A-dimension” (clearance) between the synchronizer ring and the gear. If the clearance is below ZF’s wear limit, the synchronization will fail.

  5. Alignment: Ensure the lugs of the synchronizer cone are perfectly aligned with the slots in the synchronizer body to avoid crushing the component during gearbox casing assembly.
