When installing shoes, tighten the shoe bolts in the numerical sequence, shown below, using the following procedure:1. Tighten the bolts in numerical sequence until all mating surfaces are pulled together.2. Tighten the bolts in numerical sequence to 350 50 lb. ft. (475 68 N m).3. Tighten the bolts in numerical sequence another 1/3 turn.
SHOE BOLT TIGHTENING SEQUENCETrack Shoes
Remove shoes before rebuilding to prevent damage to the rubber belt from welding (heat and weld splatter).
Measure track shoe grouser height monthly. New grouser height is 1.75 inches (44.5 mm). Grousers tend to wear more at the ends than at the center of the shoe. When grousers measure 1.00 inch (25.4 mm) at the center of the shoes, either rebuild or replace.Allowing grousers to wear beyond this limit can cause track shoe and/or bolt breakage. Shoe must be flat within .088 inch (2.2 mm) after rebuild (parallel length-wise to grouser).Replace cracked or broken shoes immediately. Inspect tapping blocks and mounting bolts. Replace with new ones if they are damaged. Thoroughly clean all contact surfaces before installing new shoes.Carcass Inspection
Inspect the tires weekly for cuts, gouges and breaks. Immediate repair of a damaged carcass can prevent total tire failure. Any cut over .375 inch (9.5 mm) deep should be repaired by a Caterpillar dealer. If a water spray shows a cut to be leaking, the carcass must be removed from the vehicle for repair.Belt Inspection
Total belt failure can cause extensive damage to vehicle.
In severe working conditions the reinforcing steel cables molded within the rubber belt body can become damaged. Weekly inspection of the belt and carcass is strongly recommended to minimize the possibilities of total failure, which can cause extensive damage. This inspection should be on a continuous basis throughout the life of the tire. The following items are important points to look for during belt inspection.1. Inspect for deformation of the molded rubber ribs on the outer circumference of the mounting belt. These ribs can be inspected at the joints between each steel shoe. The ribs are molded straight across the belt, but become deformed when steel reinforcing cables fail within the mounting belt.This deformation usually occurs at the ends of the molded rib near the belt edges and appear as a slight "S" bend in adjacent ribs. Change in direction of deformation of two adjacent ribs identifies the location of a possible failure. Mark the location and inspect frequently.If the length of the deformation in the molded rib exceeds 4 inches (101.6 mm), the belt should be removed and a new one installed.
MAXIMUM DEFORMATION OF MOLDED RIB2. Inspect for splits on the edges of the mounting belt. These edge splits may appear at the bond line of rubber to anchor plate and at locations between the anchor plates. The edge split identifies a potential failure area which should be verified, if present, by further inspecting the molding rib deformation on the belt outside diameter.An edge split alone does not indicate replacement of the belt; however, if further inspection
