5. Tighten the first nut on each locking bolt evenly against the locking clamp to tighten it by pushing the clamp away from the framehead and pulling against the back of the speed sensor gear, then torque the nuts to 27 to 31 lb.-ft. (36.6 to 42 Nm).

6. While holding the first nut on each locking bolt in place with a wrench, torque the jam nut on each locking bolt to 27 to 31 lb.-ft. (36.6 to 42 Nm) to prevent loosening during shipment.

7. Put the two bearing housing bolts and washers into a bag-tag and fasten it to the rotor locking clamp, with instructions to re-install and torque to the proper value upon removal of the clamp assembly.

<b>Note:</b> Using a wood beam and threaded rod to force the pinion towards the motor frame is an acceptable alternate method of preventing rotor bearing damage while shipping a traction motor not in a combo.

<b>Note:</b> If both of the above configurations of rotor locking methods are available (clamp with a hard stop and clamp without a hard stop), the configuration with a hard stop (nuts welded to the locking bolts) is the preferred configuration.
