Post-assembly check
1. After installing the brake drum on the axle shaft, tighten the lock nut to the required torque.
Tightening torque: 175 Nm (18 kg·m).
2. Rotate the wheel hub 10 times in both directions and make sure it rotates freely.
3. Attach the dynamometer to the hub bolt, pull at 10±2 rpm and measure the turning torque.
Turning torque: 0.20-0.95 N·m (0.02-0.09 kg·m)
Dynamometer reading: 4-19 N (0.41-1.94 kg)
