1 Attach spring test balance to circumference of pinion housing using e.g. a girth strap.
2 Place pinion housing together with drive pinion in workshop press.
Select a suitable sleeve and place against inner race of tapered roller bearing.
3 Apply a load of approx. 16 tons to the drive pinion bearing.
4 Pull on the spring test balance , read the measuring scale and note the value for the pulling force on the circumference of the pinion housing (F_ZUG).
5 Calculate friction torque of tapered roller bearing (M_REIB).
M_REIB = F_ZUG X R
M_REIB: Friction torque of tapered roller bearing
F_ZUG: Tensile force at circumference of pinion housing
R: 1/2 X outside diameter of pinion housing
