💡 How do you properly seat a split taper bushing on a drive shaft for maximum torque transfer?
Proper installation follows a tight sequence to maximize grip.
- Wipe the shaft clean before sliding the bushing onto the solid axle groove
- Align the integral keyseat with your drive shaft cut to stop twisting under load
- Tighten the taper bolts evenly so the cast iron expands and bites hard into the steel
- Set the lock screw over the keyway to prevent vertical shaft movement during heavy vibration
