GLASS-SLIDING 2124216 - Caterpillar

Start By:a. remove cylinder head assemblyb. remove oil pan 1. Remove the bolt that holds piston cooling jet (1) in position. Remove the piston cooling jet.2. Check the connecting rods and caps for their identification mark and location. The connecting rod and the rod cap should have the cylinder number etched on the right side as indicated by the arrow. If not marked, etch each unmarked connecting rod/or cap during removal.3. Remove rod cap bolts (2) and the cap from the connecting rod. Remove the lower half of the bearing from the cap. 4. Push piston and connecting rod (4) away from the crankshaft; then remove the upper half of rod bearing (5).5. Remove the piston and connecting rod from the cylinder block.6. Repeat Steps 1 through 5 for the other piston and connecting rod assemblies. The following steps are for the installation of the pistons and connecting rod assemblies.7. Put clean engine oil on the piston rings, piston and in the cylinder bore. 8. Position the piston ring end gaps 120 degrees apart. Install Tool (A) to compress the rings.9. With the number one crankshaft throw at bottom center, install the piston and connecting rod.10. Line up the connecting rod with the crankshaft. Using a soft faced hammer, carefully tap the piston into the cylinder bore until Tooling (A) comes off of the piston.11. Before the connecting rod comes in contact with crankshaft, install the upper half of the rod bearing. Be sure the bearing tab properly engages the with slot in the connecting rod.12. Put clean engine oil on the upper rod bearing surface. Using a soft faced hammer, tap the piston down while guiding the connecting rod onto the crankshaft.13. Position the lower half of the rod bearing in the corresponding numbered rod cap. Be sure the bearing tab engages with the grove in the rod caps.14. Put clean engine oil on the lower rod bearing surface; then install the rod cap. Install the bearing cap on the connecting rod with the number on the bearing (rod) cap on the same side and same number as on the connecting rod.15. Put 2P2506 Thread Lubricant on the threads of rod cap bolts (1) and the seating surfaces of the caps. Install rod cap bolts (1). Tighten them to a torque of 130 7 N m (95 5 lb ft). Mark each bolt head, and then tighten each rod cap bolt an additional 1/6 60 5 degrees ( turn).16. Repeat Steps 7 through 15 for the remainder of the piston and connecting rod assemblies.17. Install piston cooling jets (1).End By:a. install oil panb. install cylinder head assemblyDisassemble & Assemble Piston & Connecting Rod Assemblies
Start By:a. remove piston and connecting rod assemblies 1. Use Tooling (A), and remove piston rings (1) from piston crown (2). 2. Remove plug (3), and remove the piston pin. Separate piston crown (2), piston skirt (4) and connecting rod (5).
The connecting rod must be heated for the installation of the
