Use only a soft faced hammer to tap the connecting rod cap when separating the connecting rod cap from the connecting rod. Failure to use a soft jawed vise and a soft faced hammer may result in damage to the connecting rod assembly. NOTICE Always use new connecting rod bolts during the installation of connecting rod assemblies that have fractured joints. Never reuse connecting rod bolts during the reassembly of fractured joint connecting rods. Reusing connecting rods bolts during reassembly of fractured joint connecting rods may result in engine damage. 1. Ensure that the fractured joints of the connecting rod are clean prior to installation. Use compressed air or a wire brush to clean the joints. 2. Apply clean engine oil to the pistons, the piston rings, and the cylinder bore. Illustration 1 g00634923 3. Position the piston rings so that the end gaps are located 120 degrees from each other. Install Tooling (A) in order to compress the piston rings. 4. With the number one crankshaft throw at the bottom center, install the piston and connecting rod in the engine. Ensure that the proper piston and connecting rod are in the corresponding cylinder with the bearing retainer notch toward the right side of the engine. The etched number on the connecting rod must be positioned on the right side of the engine. 5. Line up the piston and the connecting rod with the crankshaft. Use a soft faced hammer and tap the piston into the cylinder bore until Tooling (A) comes off of the piston. https://127.0.0.1/sisweb/sisweb/techdoc/techdoc_print_page.jsp?returnurl=/sis... 2020/5/16

ISJ HEX COMMONALITY CHART BKH00001-UP (MACHINE)(SEBP5600 - 00) - ... 2/3 Note: Cat does not recommend the checking of the actual bearing clearances particularly on small engines. This is because of the possibility of obtaining inaccurate results and the possibility of damaging the bearing or the journal surfaces. Each Cat engine bearing is quality checked for specific wall thickness. Note: The measurements should be within specifications and the correct bearings should be used. If the crankshaft journals and the bores for the block and the rods were measured during disassembly, no further checks are necessary. However, if the technician still wants to measure the bearing clearances, Tooling (A) is an acceptable method. Tooling (A) is less accurate on journals with small diameters if clearances are less than 0.10 mm (0.004 inch). NOTICE Lead wire, shim stock or a dial bore gauge can damage the bearing surfaces. The technician must be very careful to use Tooling (A) correctly. The following points must be remembered: Ensure that the backs of the bearings and the bores are clean and dry. Ensure that the bearing locking tabs are properly seated in the tab grooves. The crankshaft must be free of oil at the contact points of Tooling (A). 1. Put a piece of Tooling (A) on the crown of the bearing that is in the cap. Note: Do not allow Tooling (A) to extend over the edge of the bearing. 2. Use the correct torque-turn specifications in order to install the bearing cap. Do not use an impact wrench. Be careful not to dislodge the bearing when the cap is installed. Note: Do not turn the crankshaft when Tooling (A) is installed. 3. Carefully remove the cap, but do not remove Tooling (A). Measure the width of Tooling (A) while Tooling (A) is in the bearing cap or on the crankshaft journal.
