Many vehicles with Weber DGV carburetors (DGV, DGAV, DGEV, and DGAS) use throttle linkages that pull directly on the throttle shaft bellcrank, introducing a side loading force instead of a pure rotating force. This side loading wears out the throttle shaft bore, eventually causing vacuum leaks, sticking throttles, and running problems. These precision double-sealed bearings are an easy, inexpensive cure. The bearings slip into the throttle shaft bore at each end of the throttle shaft with no machining necessary. Simply remove the linkage and the throttle plate, slip out the thottle shaft, and install the bearings. Kit includes two bearings and two throttle plate screws. One kit repairs one shaft (the primary side tends to wear more than the secondary). SCCA legal for all classes.
