Fuel pump gears are critical to fuel delivery, constantly subjected to rotational torque, high-frequency vibration, and exposure to fuel and oil. While the gear must be secured against slippage (which would halt fuel delivery), the pump assembly often requires service or disassembly for seal, diaphragm, or internal component replacement. This demands a retaining compound that offers structural holding power combined with easier removability. The optimal solution is a retaining compound engineered for structural holding power while offering the lowest strength for serviceability. INCURE WeldLock™ 338 Retaining Compound (Yellow) https://rrely.com/product/incure-weldlock-338-retaining-compound-yellow-50ml-250ml/ The INCURE WeldLock™ 338 Retaining Compound is the functional "Medium Strength" solution.

Application Steps: Installing Fuel Pump Gears For optimal performance and reliable retention of the fuel pump gear, follow these steps: 1. Surface Preparation (The Foundation) Clean: Thoroughly clean the shaft surface and the gear bore. Surfaces must be free of all fuel, oil, and old compound residue. Use an industrial cleaner or solvent (e.g., acetone) and wipe dry. Activate (If Needed): If using passive metals (like stainless steel) or if the ambient temperature is below 15∘C(59∘F), apply a chemical activator to the bond surfaces and allow it to flash off completely. 2. Product Application Apply: Apply a continuous, thin bead of WeldLock™ 338 around the full circumference of either the shaft or the internal bore of the gear.
