Measure the torque that is needed to rotate housing (2). This is the seal drag torque. Record the measured seal drag torque. Measure the seal drag torque by one of the methods that follow.
Illustration 2 g00305001
Typical Illustration (D) Bar (rolling torque).
To measure the seal drag torque, fasten bar (D) across the axle housing. Bar (D) will center the mounting face of the housing. Place the torque wrench on the bolt or the nut at the center of bar (D). While you turn housing (2) with the torque wrench, record the reading on the torque wrench. The torque wrench reading is the seal drag torque.
Illustration 3 g00353124
To measure seal drag torque, place the torque wrench on a bolt that is installed in the bolt circle of housing (2). While you turn housing (2) with the torque wrench, record the reading on the torque wrench. Use the following formula to calculate the actual seal drag torque:SDT = (C x (B + A)) / B"SDT" is the actual seal drag torque in N m."C"
