Simple Install Tips
Preparation: Before installing the new ZF part 1238304520, ensure the main shaft is completely free of debris, old grease, and burrs.
Verify Alignment: Check the internal splines of the hub against the shaft. The hub should slide on smoothly. Never use excessive force (like a heavy hammer) as this can cause micro-cracks.
Lubrication: Apply a thin layer of recommended ZF transmission fluid or high-performance assembly paste to the sliding surfaces to prevent friction wear during the initial startup.
Inspect Synchronizer Rings: As a professional ZF parts supplier, we recommend inspecting the mating synchronizer rings and sliding sleeves. If the hub is worn, these adjacent parts often require replacement to ensure perfect shifting.
Directional Check: Ensure the hub is oriented correctly according to the ZF workshop manual. Many hubs have a specific offset that must face the front of the gearbox.
