1 Fit shop-made clamp (1) around outer races of tapered roller bearings and clamp drive pinion gear in a vise.
2 Thoroughly oil tapered roller bearings and spin drive pinion gear at least 10 times.
3 Measure friction torque after at least three uninterrupted rotations and while spinning the drive pinion gear using .
