The following procedure details the rear railgear installation (refer to figure 2-5):
1.
Ensure the vehicle is resting on its four properly inflated tires. Position the rear
railgear (Item 1) below the rear mounting plates or adapter angles (Item 2) with the
hydraulic cylinder free end (Item 3) facing towards the front of the vehicle.
2.
Raise the railgear to the mounting plates or adapter angles and align the mounting
holes in the railgear with the slots in the mounting plates or adapter angles. The
railgear should be installed so that the center of the railgear pivot point is
approximately 16-

” from the ground. Use the supplied shims (Item 4) between the
railgear and the mounting plates or adapter angles as necessary.
3.
Fasten the railgear to the mounting plates or adapter angles using four ½” x 2” long
bolts, eight ½” washers and four ½” nuts (Item 5). Tighten but do not torque the four
½” fasteners as they will be torqued following the railgear alignment procedure.
4.
On Durango Models: The railgear and adapter angles can be moved forwards and
backwards on the mounting plates in order to clear any obstructions. Attempt to
position the railgear as far forward as possible and perpendicular to the vehicle frame.
Torque the

handle holder so that the it can be fastened to the rear operating valve support using
one ¼” x 1” long bolt, two ¼” washers and one ¼” nut (Item 9) and the pre-drilled
holes. The locking handle should operate freely. Torque the ¼” fastener to 12 ft-lbs.
