WEBER 40 DCOE/DCOM Throttle Plate Valve Butterfly 79°30′

This throttle plate valve butterfly is a replacement air-control plate for Weber 40 DCOE/DCOM carburetors. Installed on the throttle shaft, it regulates airflow through the throttle bore as the accelerator moves from closed-throttle progression into the main circuit and full-load operation. Correct plate geometry is important for proper shaft movement, closed-throttle positioning, progression control, and transient response.

The plate is marked 79°30′ and carries the MPN 64005.059. MPN 64005.059 Use it when servicing a carburetor with a damaged, worn, or incorrectly matched throttle butterfly. A plate with the wrong angle, diameter, or shaft interface can prevent correct seating and may affect idle airflow, throttle synchronization, and transition calibration.

Application coverage includes Spanish, EMPI, and FAJS carburetors, together with early Italian types 2, 4, 18, 20-21, 24, 25-26, 29-30, 32-35, 88-89, and 106-146. Verify the exact carburetor version and throttle-shaft arrangement before installation.

This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.

Reference/MPN: 64005.059.

Technical role: Replacement throttle butterfly for Weber 40 DCOE/DCOM carburetors, installed on the throttle shaft to control airflow through the bore.
Service relevance: Suitable for servicing a damaged, worn, or mismatched plate where incorrect seating can affect idle airflow, throttle synchronization, and progression control.

What Is Included

WEBER 40 DCOE/DCOM throttle plate valve butterfly, MPN 64005.059, marked 79°30′
Made in EU.

Important Fitment Note

Verify the carburetor family and body identification before ordering, including Weber 40 DCOE/DCOM, Spanish, EMPI, FAJS, or the applicable early Italian type code. Compare the 79°30′ marking and the plate outline with the removed part. Check the butterfly diameter, edge profile, screw-hole position, throttle-shaft interface, seating orientation, and closed-bore geometry before installation.

Confirm the code, geometry, and shaft interface against the removed throttle plate; similar carburetor bodies can use different butterfly specifications.
