What steps are involved in removing and reinstalling a crankshaft on Audi A4?

Question

Accepted Answer

Removal of the crankshaft is only possible when the engine is removed out of the automobile, though it is assumed that the flywheel, crankshaft pulley, timing chain, oil pan, oil pump, oil filter, balance shaft assembly (on four-cylinder and 3.0 liter V6 models) and piston/connecting rod assemblies have been removed. Measure the crankshaft endplay at the dial indicator prior to removal aligned with the crankshaft. Lever the crankshaft out, adjust the indicator to zero, then lever it in the opposite direction to verify the reading, a normal endplay is between 0.003 and 0.010 inch. Where there is a lack of a dial indicator, clearance can be found with the help of feeler gauges. The main bearing cap bolts should be loosened step by step and then the caps can be loosened by lightly tapping them with a soft hammer, after which they should be removed. With care, remove the crankshaft, preferably with help and refit the main bearing caps with the arrows towards the front. To install, make sure that the engine block and crankshaft are clean and checked. Set the block in an inverted position, and wipe the bearing surfaces. Install new upper main bearing inserts making sure that the oil holes fit, install the lower inserts in the caps. Measure the main bearing oil clearance with Plastigage, the value of which must be between 0.0015 and 0.0023 inch. In case of inappropriate clearance, check the cleanliness and you can take into consideration alternative bearing sizes. After wiping out Plastigage residue, wipe the faces of bearing inserts and place a layer of grease or assembly lube on them before replacing the crankshaft. Install main bearing caps, lubricate bolt threads with clean engine oil, and screw in that order. Re-check crankshaft endplay, turn crankshaft and verify it moves freely and then replace new rear main oil seal.
