Pinion Total Rotation Torque Check

Required Special Tools: 

• MB991006: Preload Socket

1. Using the special tool preload socket (MB991006) to rotate the pinion at a rate of one turn per 4 to 6 seconds, and then measure the pinion total rotation torque.

   Standard value: 

   Total rotation torque: 1.0 - 2.0 N.m (8.9 - 17.7 in-lb) 

   Torque fluctuation: 0.4 N.m (3.5 in-lb) or less 

   NOTE:

   • During measurement, remove the bellows from the gear housing.
   • Rotate the pinion by 180° in left and right directions from the neutral position, and measure the pinion total rotation torque.
