Roof Module Installation Tasks
Figure 6-1 Mounting Rail
You can mount the mounting rail directly on the cab roof using two existing bolts if the bolt spacing is between 30.5” and
46.5”. The two bolts must be at least 1/2” (12 mm) diameters and no larger than 5/8” (16mm) diameter. The two bolts must be
threaded directly into the cab and have sufficient threads for a secure installation. Use longer bolts if necessary. Spacer
washers can be used to elevate the mounting rail and clear the curvature found on some roofs. Below is a picture of a mounting
rail bolted to a tractor cab roof.
Note: The lettered holes and the dummy cable connector must be on the left side of the tractor. See Figure 6-2.
Figure 6-2 Mounting Bolt Locations
AutoFarm recommends using the two mounting brackets shown in Figure 6-3, if the cab roof does not have two strong bolts of
at least 1/2” (12 mm) diameter.
Secure the two brackets on the cab roof using two screws for each bracket. You can use smaller screws to secure these
brackets, typically 1/4” (6.35 mm) or 5/16” (8mm). These brackets fit smaller screws found on some tractor cabs. The brackets
have a series of holes plus one slotted hole to accommodate different screw spacings.
