Installation Steps

1. Prepare Tools & Clean Surfaces: Gather standard wrenches, a torque wrench, and cleaning supplies. Thoroughly clean the motor shaft, coupling bore, and keyway to remove dust, oil, or rust—any debris causes misalignment or wear.
2. Fit the Key: Insert the key into the motor shaft’s keyway, ensuring a precise fit with minimal top gap to maintain dynamic balance.
3. Mount the Coupling Half: Apply a thin layer of lubricant to the motor shaft. Align the coupling half with the shaft and slide it on until it seats firmly against the shaft shoulder.
4. Align & Secure: Align the coupling with the mating air compressor component. Tighten bolts evenly in a crisscross pattern to the manufacturer’s torque specifications, avoiding over-tightening.
5. Final Inspection: Rotate the shaft by hand to check for smooth, interference-free movement. Verify alignment and bolt tightness before restarting the compressor.
