Throttle Shaft Bearings - Weber 40 45 DCOE 44 IDF

• Factory-sealed to prevent vacuum leaks from degraded grease
• Direct-fit for Weber 40 45 DCOE and 44 IDF carburettors
• Improves throttle response and idle consistency

These throttle shaft bearings are a critical upgrade for ageing Weber carburettors. The original open grease-pack bearings are prone to breakdown over time, allowing unmetered air to enter the intake and causing poor idle, flat spots, or tuning difficulties. These sealed bearings eliminate that issue by preventing vacuum leaks through the shaft bore, ensuring reliable performance and smoother throttle operation. Ideal for restoration, performance tuning or preventative maintenance.
