Simple Install Tip:
Because the 1st/2nd gear hub handles the most load, correct installation is vital:
Check Hub Orientation: The 1272304130 hub often has a specific orientation. Check for “Front” markings or refer to the ZF technical diagram to ensure the correct face is pointing towards the engine side.
Inspect Main Shaft Splines: Before sliding the new hub onto the shaft, inspect the main shaft splines (e.g., part 1272304058) for any burrs or wear. A tight, clean fit is mandatory.
Replace Synchro Springs/Keys: When replacing the hub, it is highly recommended to install new synchronizer keys (pressure pieces) and springs. A new hub with old springs can cause inconsistent shifting.
Avoid Direct Impact: Use a professional hydraulic press or a heated installation method (if specified). Striking the hub with a steel hammer can cause micro-fractures in the forged steel, leading to failure under high torque.
Cleanliness: Ensure no metal shavings or old assembly grease remain in the hub’s teeth, as these can contaminate the transmission oil and damage the synchronizer rings.
