Taper Lock 2012 installation tips
- Stop the drive and secure it against starting. Check the condition of pulley, bushing and shaft, and compatibility of their designations.
- Clean and degrease the shaft and tapered surfaces of the bushing and pulley seat. Align the half-holes according to the instructions. Lightly oil the screws; do not lubricate tapered surfaces.
- Position the assembly on the shaft. If a key is used, maintain the required clearance above it. Check pulley alignment and tighten the screws evenly with a torque wrench.
- The Optibelt 2012 bushing uses two screws and a tightening torque of 31 Nm. For a bushing from another brand, use its manufacturer's instructions; do not transfer the torque automatically.
- After approx. 0,5–1 hours of operation, stop and secure the drive, then check tightening torque, alignment and belt tension.
