Diagram ref no 23

Transmission bearings support rotating shafts and gear clusters under high loads and speeds. Over time wear, misalignment or contamination in the gearbox can cause bearing failure, leading to increased friction, vibration, noise or even gearbox damage. Correct bearing fit is essential for longevity and precision of the transmission.

When to replace:
• During any gearbox overhaul or rebuild, especially when shafts or collar nuts are removed.
• If you notice unusual gearbox noises (rumbling, growling) or shaft play during inspection.
• Whenever replacing major gearbox components—such as synchros, shafts, or other bearings—as a preventive maintenance measure, ensuring optimal alignment and performance.
