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: 0.6 - 1.6 N.m (5.3 - 14.2 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.
2. If the measurement value is outside the standard value, replace the gear housing (Refer to DISASSEMBLY AND ASSEMBLY  ).
