Many vehicles with Weber DGV downdraft carburetors (DGV, DGAV, and DGEV) 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 in place of the nylon shaft bushings. Straight drop-in fit for 32/36 DGV (including 5A), 32/36 DGAV, and 32/36 DGEV carburetors.
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.
Does not fit any DF series (DFV, DFAV, DFT, etc), DGS/DGAS/DGES, DIR, or ICT carburetors. The DF series, DIR, and ICT were not equipped with the nylon throttle shaft bushings that these bearings replace. The spigot on DF series and DIR carburetors is too small to machine to accept these bearings. The DGS/DGAS/DGES and ICT series were originally equipped with a PTFE shim or bushing to prevent throttle shaft bore wear.
Note: Fits genuine Weber (made in Italy or made in Spain) carburetors only! Does not fit most copies, Asian knock-offs, or work-alikes.
