  Q: What are the risks and procedures involved in removing the crankshaft on Volkswagen Golf SportWagen?

  A:

  Removal of the crankshaft may permanently damage the bearing block on engines with 1.4L engines because the crankshaft bearing cap bolts may deform the cylinder bearing block and lead to bearing damage, it is thus advisable not to remove the crankshaft. The crankshaft is accessible only when the engine is removed out of the car, supposing that the flywheel, crankshaft pulley, oil seal flange, timing belt or chains, oil pans, oil pump body, control housing cover, oil filter, and piston/connecting rod assemblies were already disassembled. In the case of four-cylinder engines, the rear main oil seal retainer has to be unbolted before moving to the next step. Measure the crankshaft endplay with a dial indicator before removing and make sure that it is within the limits. In the absence of dial indicators, it is possible to use feeler gauges and establish clearance. Relax the main bearing cap bolts slowly then remove the caps then slowly remove the crankshaft, preferably with help as it is heavy. To install, make sure the engine block and crankshaft is clean and checked, hold the block so that the bottom is up and place new bearing inserts making sure that the oil holes are aligned. Check the main bearing oil clearance with Plastigage, and should the need arise, change bearing inserts with the right sizes on the basis of the measurements. Clean all the surfaces and apply a thin coating of grease or assembly lube to the bearing surfaces, then replace the crankshaft, and fit the main bearing caps in their proper order of adding the correct torque. Check crankshaft endplay again, and make sure that it turns freely with the least amount of resistance, taking care of any problem that might exist before ensuring that a fresh rear main oil seal is installed.
