Illustration 1 g01878233Note: Refer to the arrows in Illustration 1 for the approximate location for attaching the suitable restraining devices and lifting devices to the machine. The suitable restraining devices and the lifting devices must be centered in the fore and aft direction on the bottom guards.Note: Ensure that all hinge pins, cotter pins, and washers are in place in the bottom guard. Do not remove any of these parts. Inspect both halves of the hinges. Make sure that both halves of the hinges are properly attached to the bottom guard and the tractor frame. If any cracks are observed on the hinges or the hinge welds, make suitable repairs prior to raising the bottom guard.Note: The weight of the forward bottom guard is approximately 204 kg (450 lb). The weight of the rear bottom guard is approximately 329 kg (725 lb). Bottom guards may contain a significant amount of rock, dirt, liquids and debris, which will result in significant additional weight.

Typical Example
Attach the suitable restraining device (1) to the side of the machine on the hinged side of the bottom guard. Attach Tooling (A) or a suitable lifting device to the other side of the machine. Acceptable locations include the track or the bulldozer push arm. An external hoist is an acceptable alternative to Tooling (A) but care must be taken in order to avoid fouling the hook on a corner of the tractor. If a pusher bolt was used to open the bottom guard, remove the pusher bolt. Attach the suitable restraining device (1) onto Tooling (A) and pull tightly in order to firmly secure the bottom guard (2) into the correct position. Make sure that the bolts go through the holes in the guard.

Typical Example
Install nuts (3) that secure bottom guard (2) to tractor frame (4). Install nuts (3) that are closest to you first. Install the nuts that are farthest away from you last in order to prevent the need to reach across the loosened guard. Make sure that all of nuts (3) have been tightened before removing the restraining device.
