A coupling of this type transmits rotational drive from the motor to the oil pump in an oil-fired burner. It sits between the motor shaft and the pump shaft, typically using an elastomeric insert to absorb vibration and allow minor misalignment. The insert is the component that wears over time; a worn coupling can cause noise, vibration, or loss of pump speed, which affects fuel delivery and firing rate. When selecting a replacement coupling, the key parameters are the bore diameters for the motor and pump shafts and the overall length. The insert material must be compatible with the operating temperature and the presence of oil. During installation, ensure the shafts are aligned within the coupling’s tolerance: excessive misalignment will accelerate wear and can damage the pump shaft seal. Always check that the replacement coupling matches the existing shaft keyways and that the retaining screws are properly torqued. No further details are available for this specific article beyond its part number and brand. If you are sourcing a coupling for a particular burner model, confirm the shaft dimensions and the coupling type (e.g., jaw, pin-and-bush) against the original part.
