What This Product Does

The socket forms the joint between a linkage rod and its mating ball, allowing the connected mechanism to articulate as the rod moves. It is a linkage component rather than a fuel-metering part, so it should not be confused with a jet, valve or carburettor repair kit.

The supplied diagrams also identify this reference in mechanical-injection throttle assemblies and the 356 heating-air control assembly. These are application-specific uses; compare the existing connection and thread before selecting a replacement.

Functions

• Connects the linkage rod to its mating ball.
• Allows movement at the linkage joint.
• Transfers rod movement to the connected control mechanism.

Symptoms of Fault

A sticking throttle or visibly worn linkage warrants inspection of the socket, mating ball and adjoining components. Hesitation or an irregular idle can have other causes, so these symptoms alone do not establish that the socket needs replacement.

Why Replacement Matters

Renewing a worn or damaged socket addresses deterioration at the linkage connection. Check the mating ball and other joints at the same time, since replacing one component will not correct wear elsewhere. The quantities recorded in the diagrams describe the assemblies, not the number supplied.

FAQs

• Is this a left-hand-thread socket?
  No. this is a right-hand thread; confirm the thread on the component being replaced.
• Does replacement require a complete carburettor rebuild?
  Not necessarily. Assess the linkage separately from the carburettor body and internal fuelling components.
• What checks follow linkage work?
  Check free movement and the relevant linkage adjustment. Where carburettor settings have been disturbed, synchronisation and mixture adjustment may also be required.
