CONTROL GP-UNPROGRAMMED 4642924 - Caterpillar

Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Inspect the pins of the crankshaft for damage. If the crankshaft is damaged, replace the crankshaft or recondition the crankshaft. Refer to Disassembly and Assembly, "Crankshaft - Remove" and Disassembly and Assembly, "Crankshaft - Install". Ensure that the connecting rod bearings are clean and free from wear or damage. If necessary, replace the connecting rod bearings.
Illustration 1 g01317759
Typical example
Clean the bearing surface of connecting rod (1) and connecting rod cap (5). Ensure that number (X) on connecting rod cap (5) aligns with number (X) on connecting rod (1).
Install upper connecting rod bearing (3) to connecting rod (1). Lubricate the bearing surface of the connecting rod bearing with clean engine oil.
Carefully pull connecting rod (1) against the crankshaft pin. Note: Use tape or rubber tubing on connecting rod bolts (2) in order to protect the crankshaft journals. The sharp edges of the connecting rod bolts could damage the crankshaft journals.
Clean the connecting rod cap. Install lower connecting rod bearing (4) to connecting rod cap (5).
Lubricate the pin of the crankshaft and lubricate lower connecting rod bearing (3) with clean engine oil.
When the connecting rod caps are installed, ensure that the identification marks are aligned.
Install connecting rod cap (5).
Install nuts (4). For C0.5 and C0.7 engines, tighten nuts (4) to a torque of 23 N m (16 lb ft).For C1.1 and C1.6 engines, tighten nuts (4) to a torque of 32 N m (24 lb ft).For C1.5 and C2.2 engines, tighten nuts (4) to a torque of 52 N m (38 lb ft).
Ensure that the installed connecting rod assembly has tactile side play. Carefully rotate the crankshaft in order to ensure that there is no binding. Note: If all connecting rod bearings require replacement on a four cylinder engine, the procedure can be carried out on two cylinders at the same time. The procedure can be carried out on the following pairs of cylinders. 1 with 4 and 2 with 3. Ensure that both pairs of the connecting rod bearings are installed before changing from one pair of cylinders to another pair of cylinders.
