In the steps that follow, the terms track clamp, clamping nut, and locking nut are used.
Notice where they are on the mount.
9 Centered between the ties and on the rail closest to the bungalow, place the mount so
that the moveable track clamp extends under the rail and toward the center of the
track.
10 Tighten the inner nut (that is, the clamping nut) by hand.
This should hold the mount in place.
11 Using a short-handle 1-1/2-inch wrench, tighten the clamping nut to a torque of 48 to
50 foot-pounds (65.1 to 67.8 newton-meters) .
Don't exceed a torque of 50 foot-pounds (67.8 newton-meters). Doing so can
cause failure of the mount.
12 Using a short-handle 1-1/2-inch wrench, tighten the locking nut to a torque of 48 to
50 foot-pounds (65.1 to 67.8 newton-meters) .
Don't exceed a torque of 50 foot-pounds (67.8 newton-meters). Doing so can
cause failure of the mount.
At this point, your work should look like this.
The next step is necessary to finish installing the bearing scanner mounts, to install the
