Threading the Bolts Through the Carcass of the BeltInstalling and Tightening the Bolts
The following step is usually performed after a batch of bolts have been installed and the belt has been repositioned to work on the next section of the belt.All of the bolts should protrude out of the carcass of the belt by approximately the same distance. The washer and the nut should be easily started. See Illustration 16 and 17.In some cases, an air chisel or a wood boring bit with a 31.8 mm (1.25 inch) diameter will be needed in order to trim the tread bar around the area of the bolt. This will help in starting the nut of the bolt. In many cases, the bolts will not interfere with the tread bars. This is especially true with belts that were manufactured after 1997. See Illustration 17. An air wrench that is used in combination with a ratchet and socket can be used in order to tighten the bolt. The nut should be tightened until the washer is compressed into the carcass of the belt.Make sure that all of the bolts equally protrude through the carcass of the belt. Make sure that the washers that are inside of the guide blocks are not loose. If the washers that are inside of the guide blocks are loose, the guide blocks are not properly secured.

Drill two countersunk holes.
The two pilot holes for the bolts should be drilled through the guide block, up to the carcass of the belt. Use a 5/8 inch boring bit. The pilot hole will end up being smaller.
Drill two pilot holes for the bolts through the carcass of the belt. Use a metal drill bit with a diameter of 11.2 mm (0.44 inch). The cobalt drill bit or the titanium coated drill bit should be at least 8 to 9 inches long.After you complete Step 1 through Step 3, use the steps in the earlier sections in order to install the bolts. The following paragraphs explain the details of the steps that are mentioned above.Mark and Drill the Countersunk Holes
The countersunk hole is added by using a 31.8 mm (1.25 inch) wood boring bit. See Illustration 19. Use dimension (B) for the correct depth of the countersunk hole.Note: The hole will be smaller than the diameter of the boring tool due to the compression of the rubber.Drill the
