SHAFT THROTTLE CARTER CARBURETOR OVER SIZE
WO116585
Throttle Shaft Oversize Carter Carburettor
Repair solution for worn throttle shaft bearing
Oversize throttle shaft for repairing Carter carburettors with worn bearings in the throttle body. Wear creates play between the shaft and the housing, resulting in vacuum leaks, irregular idle speed and poor engine performance. This oversize shaft offers a durable repair solution without having to rebore the housing and fit bushings.

Application
This oversize throttle shaft is specifically developed for Carter carburettors where the bearings in the throttle body are worn. Throttle shaft wear is a common problem with older carburettors, especially on the outside where the pedal linkage exerts pulling force. The wear is usually egg-shaped due to uneven loading. Suitable for carburettors where standard shaft diameter no longer provides sufficient sealing.
Installation notes
Installation requires dismantling of the throttle body and removal of the old throttle shaft including throttle plates. First check that the wear is indeed in the housing and not on the shaft itself. Measure the bore on different axes as wear is often egg-shaped. The oversize shaft must fit with minimal clearance for optimal sealing. Use Loctite on the throttle plate screws and stake the protruding ends to prevent loosening. The alternative is complete rebushing with bronze bushings and reaming, but this requires a milling machine and specialist tools.
Compatibility
Please note: oversize shafts are only required when the throttle body bore is worn. For new or lightly worn housings, a standard throttle shaft must be used. Always check the condition of both shaft and bore - sometimes only the shaft is worn and rebushing with standard shaft may suffice. This solution is not suitable for extreme wear where the larger section of a stepped bore is also damaged.
Historical context
Throttle shaft wear has been a known problem with Carter carburettors for decades. Originally, rebushing with bronze bushings and reaming was the only solution, a labour-intensive process requiring specialist tools. Oversize shafts were introduced later as a faster field repair.
