CYLINDER ENGINE 20. Place a piece of Plastigauge across the centre of the crankshaft main bearing journals. 21. Locate the bearing lower shell into the main bearing cap. 22. Fit numbers one to four main bearing caps and shells. Torque: to 7,6 kgf m (50 to 55 Ibf ft). 23. Fit the rear main bearing cap and shell. Torque: to 9,6 kgf m (65 to 70 Ibf ft). Do not allow the crankshaft to be rotated while the Plastigauge is in 24. Remove the main bearing caps and shells. measure the flattened Plastigauge at its widest 26. The graduation that most closely corresponds to the width of the Plastigauge indicates the bearing clearance. The correct bearing clearance with new or overhauled components is 0,023 to 0,065 to 0.0025 in). 28. If the correct clearance is not obtained initially, use selective bearing assembly. 29. Wipe off the Plastigauge with an rag. Do NOT scrape it off. 30. Maintain the bearing shells and caps in sets and in the correct sequence. Renew spigot bearing 31. Carefully remove the old bearing. of 1,6 (0.063 in) below the end face of the crankshaft. 33. Ream the spigot bearing to 19,177 + 0,025 (0.7504 0.001 in) inside diameter. Ensure all swarf is removed. ASSEMBLING ENGINE FIT CRANKSHAFT AND MAIN BEARINGS 1. Locate the upper main bearing shells into 2. Locate the flanged upper main bearing shell in the centre position. 3. Lubricate the crankshaft main bearing journals and bearing shells with clean engine oil and lower the crankshaft into position. |
