The elimination of the crankshaft requires that the engine be pulled out on the vehicle. Before taking the crankshaft away, it is measured using a dial indicator or feeler gauges to find out about endplay. Therefore, one should gently tap assembly with a soft-face hammer to release it from cylinder block as well as loosen main bearing cap/bedplate bolts. At this stage, another person assists in lifting crankshaft from engine very carefully. During installation, this engine block is placed bottom side up and main bearing cap assembly is removed. In addition, original bearing inserts are taken out and surfaces cleaned. Further still, new upper main bearing inserts are put in all main bearing saddles ensuring oil holes are properly lined up inside them; thrust washers are situated in right journal while lower main bearing inserts fitted into main bearing cap. Then clean faces of blocks with the journal rings and crankpin journals for bearings installations. Afterward, lay crankshaft into its position within cylinder block and verify clearance between it and other parts by using Plastigage method. The following step is putting the main bearing cap assembly onto both crankshaft's one end and cylinder block then fastening nuts appropriately. Now, remove plastigauge and scrape off any burs from contact surface of bearings If necessary lift out piston shaft from inside cylinder through these square windows which enables positioning thin film lubricating fluid on each one of bearings against rotating shaft in its place again similar manner as previously mentioned above before having returned said part back into said surrounding machined aperture there being also supplied with subsequent removal lubricated afterwards cleaning annealed metal surfaces by means again given next words since therefore towards after before although yet because so if otherwise however except along beside etc.; The main bearing cap or bedplate is installed onto the crankshaft and cylinder block, and the bolts are tightened to the specified torque. Re-measure crankshaft endplay and turn it over by hand to ensure that it moves freely. Finally, insert the rear main oil seal.
