Caterpillar Products: AllIntroduction
This Special Instruction contains the procedures and the information for the installation and removal of the Mechanically Attached Wear Plate System.The Mechanically Attached Wear Plate System is available in four sizes. The system has a range of thickness from 35 mm (1.38 inch) to 100 mm (3.94 inch). The Mechanically Attached Wear Plate System provides a hammerless means of installation and of removal of wear plates. The system is intended to protect the areas that were previously unprotected or the areas that were protected by weld-on wear plates or by bolt-on wear plates. The Mechanically Attached Wear Plate System is available for a large variety of applications on Caterpillar and on non-Caterpillar equipment.The wear plates are available for standard applications and for heavy-duty applications. The wear plates are made from Caterpillar formulated DH-2 steel. To obtain optimum strength and optimum wear life, a through hardened steel is used. The base plate is made from slightly softer steel but the steel is a tough weldable steel in order to withstand the high forces. The base plate is not subject to wear under normal conditions since the base plate is entirely covered by the wear plate. The patented compression retainer is investment cast from a spring steel material. The retainer acts as a spacer when the retainer is located in the holding position. As a system, the Mechanically Attached Wear Plate System will accept loads from any direction. The Mechanically Attached Wear Plate System does not require specific orientation when the wear plates are compared with competitive wear plates. The only requirement for the system is approximately 50 mm (2 inch) of space from adjacent objects in order to facilitate replacement.The Mechanically Attached Wear Plate System can be installed on most flat surfaces or on moderately curved surfaces. Refer to ""Parts List"" for the limitations of the radius. The following list is the possible applications for protection by use of wear plates: bucket bottoms and bucket sides, bulldozer push arms, excavator bucket ski runners, excavator bucket sides, truck body duck tails, Tiger bulldozer blades and crusher hoppers. The system has the following features: long life, ability to customize the protection and ease of use. These features help the system to become a popular alternative to bolt-on wear plates or to weld-on wear plates.The wear plate has recessed holes (blind holes) that are cast into each corner. The holes serve as a wear indicator that makes inspection quick and easy. When the holes become exposed in one or more of the corners, the wear plate must be changed. If the wear plate is allowed to wear beyond the wear indicator, damage to the base plate may occur.Read the entire special instruction. Understand the information before you perform any of the procedures. Understand the information before you order any of the parts.The suggested tools and equipment should be readily available. If the tools are not available, assembly will be more difficult and more time will be necessary to complete the
