FAQ

First, ensure the bore of the pulley and the outside of the bush are clean and free of oil or debris. Align the half-threaded holes in the pulley with the half-plain holes in the bush. Lightly oil the threads of the set screws and insert them. Slide the assembly onto the shaft, position it, and then progressively tighten the screws to the manufacturer's recommended torque value to ensure a secure fit.

Proper belt tension is crucial for performance and longevity. Use a tension gauge to measure the force required to deflect the belt at the center of its span. Refer to the belt manufacturer's guidelines for the specific tension values for your 8M belt, considering factors like shaft speed, load, and center distance.

Inspect the tooth flanks for any signs of polishing, grooving, or material loss, which can indicate misalignment or excessive tension. Check for any wobble or run-out when the pulley is rotating, as this could point to a worn bore or a problem with the bush installation.
