10 CAT GRADER EDGES... Job-matched for Most Efficient Blade Performance Caterpillar offers three types of grader edges curved, flat and serrated. The standard curved type is offered in two widths, four thicknesses and six lengths to fit every possible job condition and moldboard. The standard flat type is offered in two widths, four thicknesses and four lengths. All Cat grader edges are made of tough, thru-hardened DH-2 steel for strength and wear resistance. They are unconditionally guaranteed against breakage. CAT MOTOR GRADER CUTTING EDGE APPLICATION GUIDE For Most Applications Recommend curved or flat 0.63" (16 mm) or 0.75" (19 mm) thick edges. The thicker, 1" (25 mm) edges should be used when abrasive wear is a greater problem than penetration; the thinner edges when penetration is critical. Recommend 8" (203 mm) wide edges for more wear material and fewer edge changes. For Finish Grading Recommend 0.50" (13 mm) thick curved edges. They provide good pene - tra tion and stay sharp longer. There is less throw-away iron than with thicker edges. For Severe Applications Recommend 1.38" (35 mm) thick by 10" (254 mm) or 1" (25 mm) thick by 10" (254 mm) wide flat edges. They provide maximum strength and wear material. In severe applications these edges will provide the lowest material costs per hour. For Maximum Penetration Recommend 0.75" (19 mm) thick serrated edges. Serrated edges exert more down pressure per square inch of contact area for improved penetration in frozen or hard-packed materials. In heavy-duty applications, 1" (25 mm) by 10" (254 mm) flat or 1" (25 mm) by 8" (203 mm) flat or curved serrated edges may be used. In extreme conditions, serrated edges can be installed over standard 6" (152 mm) edges for extra strength. For High Abrasion/Low Impact Applications Caterpillar offers two different types of carbide edges. They are the tungsten carbide tile edges and the tungsten carbide insert edges. Both provide many times the wear life and lower cost per hour than standard DH-2 edges if used as recommended, in low to medium impact, highly abrasive applications such as maintenance of unpaved, sand and gravel roads. The tungsten carbide tile edges are manufactured by milling a flat on the front of a steel cutting edge base and brazing tungsten carbide tiles onto the flat. They are curved for excellent penetration and are available in 2' (610 mm) and 3' (914 mm) lengths and 4.75" (121 mm) and 6.75" (171 mm) widths. The tungsten carbide insert edges are manufactured by milling a slot in the bottom of a steel cutting edge and brazing a tungsten carbide insert into the slot. The tungsten carbide insert edges have the carbide sandwiched in a groove between the front and rear surfaces of the edge to protect them from impact and therefore lend themselves to higher impact applications like snow removal. In both types of edges, the life is extended substantially due to the wear characteristics of the tungsten carbide. Warranty on the carbide edges is the same as that for GraderBits, meaning the steel edge base is covered, but not the tungsten carbide tile or insert itself.

11 Edge Width On motor grader cutting edges, width translates to wear material, so as a general rule, for the longest life, use the widest edge. An 8" (203 mm) edge, for example, will give you 100% more available wear material and edge life than a 6" (152 mm) edge at only about 35% more cost. In addition, hardware usage and total downtime will be cut by 50%. To extend cost savings even farther, a 10" (254 mm) cutting edge will last three times longer than a 6" (152 mm) edge when used under comparable conditions. Crowning describes a normal wear pattern in which the cutting edge conforms to the material being graded. When extreme crowning occurs or when finishing applications require tolerances less than 1/4" (6 mm), the best value may be in selecting a narrower and thinner cutting edge. This approach reduces costs by minimizing the amount of usable iron that must be thrown away. Edge Thickness Penetration requirements determine how thick your edge should be. The easier material is to penetrate, the thicker the edge you should use. This simple chart illustrates how wear material increases with thickness.

12 GRADER END BITS Cat moldboard and overlay end bits are made from tough, thru-hardened DH-2 steel. Moldboard end bits protect the moldboard itself from wear and damage. Overlays provide additional wear protection and strength for both the moldboard and the cutting edge. Moldboard End Bits Protects end of moldboard from wear and damage. Recommended for all applications. Reversible Overlays Used with curved edges. Protects and strengthens both moldboard and cutting edges. Reversible design provides second life for greater value. Flat Overlays Provides same moldboard and edge protection for flat edges. Not avail - able for 14G or 16G graders Q2011

13 CAT GRADERBITS SYSTEM The Cat GraderBits System is a motor grader ground engaging tool system that can offer your customers many advantages over standard cutting edges. This system is made up of adapters that bolt up to the moldboard and individual bits that fit into the adapter. The Cat GraderBits System has been designed primarily for maintaining and reconditioning gravel roads; including ice and snow removal. In addition, a continuous Cat GraderBits configuration can be used on paved surfaces. There are two major customer groups that should be targeted mines and governmental bodies. Since aggregate size is often different on governmental vs. mining haul roads, each group has an adapter designed for its needs. The mining adapter has a wide gap between the Cat GraderBits to accommodate large aggregate. Since many country roads use smaller aggregates, the gap is narrower on these adapters. Either adapter can be sold in either market providing bolt hole diameters match-up. See part number information. Features/Benefits The Cat GraderBits System has many benefits. One of the most important is the increase in wear life over standard, heat-treated edges. However, the Cat GraderBits System costs much more than a set of standard edges. Successful selling will require a customer s understanding of ALL benefits. Selling wear life as the only feature will result in fewer sales. Features Serrated design Tungsten carbide wear material Large decrease in grade blade maintenance Smoother haulroads Four Cat GraderBit widths Detailed Comments on Features & Benefits 1. One of the benefits that can be seen immediately is the ease of penetration compared to standard continuous edges. Using a serrated configuration, initial penetration is easier. Ridges are removed and trenches are filled in one pass. Material is allowed to pass between the Cat GraderBits which helps conserve gravel. All of these benefits help cut costs which will maximize profitability. 2. Tungsten Carbide is used on the Cat GraderBits at the wear area. This is the same material used in Cat abrasion-resistant material edges. It is an extremely hard alloy which offers excellent wear life in ground engaging tools. Cat GraderBit wear life will depend on the application. In a mining haulroad application, wear life should range between 6-8 times greater than heattreated edges. On county roads, it should average 8-10 times the life. A mine will typically have larger aggregate and higher impact than a county road, thus wear life is less than a county road application. Benefits Excellent penetration, conserves gravel and increases productivity 6-10 times greater wear life than standard cutting edge (10" x 1"; 254 mm x 25 mm) times greater wear life than standard cutting edge (8" x 3/4"; 203 mm x 19 mm) Reduced downtime Longer tire and mechanical life, faster travel speeds Allows several edge configurations, including continuous edge 2Q

14 3. Because of the increased wear life, blade maintenance is reduced which helps cut costs. Other systems which have rotating bits require main - tenance for proper operation. The Cat GraderBit System is relatively maintenance free. 4. Proper use of this system will result in smoother haulroads. Smoother roads promote safer travel and are easier on machines and tires which cuts repair costs. Faster travel speeds are attainable on smoother roads, which can impact cycle times for off-highway trucks and other machines. 5. Four Cat GraderBits are offered wide, standard, penetration and sharp ranging in tip width from 2.36" (60 mm) to 0.61" (15.5 mm). This allows several different edge configurations. Using the narrow gap adapter, a continuous edge can be made by using all wide bits. (This is the only configuration recommended for asphalt applications.) By alternating wide with any of the other bits, the gap is reduced which may be better suited for small aggregate. Using the sharp tip alone will give the maximum gap. The same options can be used for the wider adapter, but a continuous edge is not possible because of the wider gap between adapter holes. 6. Regardless of the GraderBits used, it is recommended to place wide GraderBits in the outermost slots. This helps reduce adapter wear on these end positions. Installation The Cat GraderBit System installs easily without moldboard modifi cation. Adapters bolt up to the moldboard like standard edges and the Cat GraderBits fit into the adapter holes and are held on with a snap ring. A snap ring pliers is the only tool necessary for installation. The tungsten carbide portion of the Cat GraderBit should point towards the front of the machine. The system can be installed on any 12, 14 or 16 foot moldboard and can be done in less than 1.5 hours. Individual bits can be removed/ installed in less than one minute. Examples of Configurations Operation Proper operation is very important to assure acceptable Cat GraderBit system life. There are five points to stress with the operators. 1. The face of the carbide tile should be perpendicular to the ground. 2. Moldboard sidecast angle should be between Penetration depth should be approximately 1-1.5" (25-38 mm) maximum. 4. Operating speed should be held to 4-6 mph. In higher impact applications, slower speeds will reduce potential for breakage. 5. If machine is equipped with an accumulator, make sure it s on when operating GraderBit System Q2011

The tungsten carbide and the braze material are warranted under the standard 6-month new parts warranty. ROTATING BIT SYSTEM Description The Cat standard rotating bit system is comprised of three or four foot long adapter boards to accommodate a 7/8" (shank) carbide-tipped bit. The adapter boards are available in either 5/8" or 3/4" bolt hole punch. There is a heavy-duty adapter board option that accepts a 1" (shank) carbide-tipped bit. The heavy-duty boards are only available in a 3/4" bolt hole punch, and are available in a three and four foot adapter board sections. All threefoot boards use 21 bits; the four-foot boards use 28 bits. The replaceable carbide bits rotate and self sharpen which allows for superior wear over conventional curved or flat carbide-insert blades. The carbide tip is also engineered with flat sides that aid in bit rotation. The rotating bit also provides improved penetration and cutting ability, which can reduce the number of passes required by the motor grader compared to conventional cutting edges. The carbide bits if maintained can last as long as 5 10 sets of conventional grader blades. The multiple uses of the rotating bit system include; reclaiming lost gravel cast to the shoulders or imbedded into the road surface, which reduces the cost of new material (gravel). The system is extremely useful in cutting compacted snow or ice, giving the road better traction than the smooth cutting conventional blade setup. Removing washboards or cutting potholes is another feature of this system, which substantially improves and sustains the condition of dirt or oiled roads. Installation 1. Remove existing cutting edges from moldboard. Clean moldboard of all dirt. 2. Bolt Cat adapter boards. Tighten bolts. Rap the bolt heads sharply with a hammer. Torque bolts a second time. 3. On level ground surface, set adapter boards perpendicular, or 90 degrees from the level ground surface. Set magnetic protractor (ex. Mayes Level + Angle Finder) on front of adapter board surface. Rack moldboard back until protractor reads 70 degrees, or adapter board should be racked back 20 degrees from perpendicular position. 4. Caution: If adapter angle is not set correctly, the moldboard will chatter and vibrate, and the rotating bits will not properly wear or rotate (flatten). If this occurs, readjust adapter boards to the correct operating angle. (See illustration) Correct operating angle 2Q

16 Operation 1. Insure that bits are rotating freely and the adapter boards are set in correct operating position. 2. Check rotation of bits daily. A bit not rotating will develop a flat wearing surface on the carbide tip, and leave a channel mark on the road. 3. In ice and compacted snow conditions, operate blade in float position with no down pressure. Grade in low gear (3rd or less). 4. If bits are not freely rotating, spray or power wash, or remove and clean debris from bit holder bore hole. Only lubricate with WD 40 or an environmentally approved lubricant. Governmental Bid Specifications for Motor Grader Edges/Bits Many governmental units periodically review their bid specifications for purchasing motor grader cutting edges and end bits. It is important to be aware of when such reviews take place and provide recommendations. Caterpillar suggests that physical properties, rather than chemical properties, represent the most accurate guide to edge performance. Where chemical properties are still included in governmental bid specifica tions, you will want to urge the purchasing authorities to review those specifications against the following physical properties and related performance benefits. 1. Through-hardened to a minimum of Rc43 (BR 400)* Through-hardening insures a uniform wear rate and these user benefits: Fewer edges to buy. Reduced downtime for removal and installation. Less hardware expense. Lower total labor expense. * Serrated edges thru-hardened to minimum Rc38 (Br353). 2. Standard bolt hole sizes and spacing 0.63" (16 mm) and 0.75" (19 mm) holes for No. 3 head cutting edge bolts. Standard Highway punching with either 6" (152 mm) or 12" (305 mm) spacing. This specification standardized both edge and hardware inventories, reducing the number of different parts required in stock. 3. Breakage guarantee Supplier warrants that if an edge breaks during operation, it will be replaced free of charge (with the exception of high-carbon edges). The guarantee translates into positive benefits: Fewer edges purchased. Users save money. Since the guarantee reduces the user s risk, he can use 8" (203 mm) wide edges instead of 6" (152 mm) wide edges in most applications. This means two extra inches of wear material are available. Cat Motor Grader edges meet all of these requirements Q2011

For scarifier shanks and tips, consult the RIPPERS/SCARIFIERS Section. Moldboard end bits should be recommended for all applications. Over lays should be recommended for high impact applications. Reversible overlays should be inspected regularly and inter-changed (end-to-end) before outside corners wear through. Users who routinely burn off end bit and edge hardware may realize substantial savings with a 5P-2410 Hand Impact Wrench which makes field installation and removal of hardware easy. 2Q
