  Q: What precautions should be taken when disconnecting the battery and Cam Gear, Camshaft and Rocker Arm for 4-cylinder engines on Volkswagen Jetta?

  A:

  When the battery has been disconnected, a number of systems will need to be re-learned until they start operating correctly. In case of mistakes, the engine will suffer serious damages; the process should not be performed by an untrained person in this kind of repair. In case uncertain of capabilities, seek advice of someone with knowledge and ensure that all work is completed before one tries to start the engine. Interim inspection of camshafts and lifters must be done before fitting, and prior to withdrawal of camshafts, endplay inspection must be done. The camshafts may not be pulled out of the camshaft housing on 1.4L (CZTA, DGXA) models, and in the situation of an issue, the camshafts and housing have to be replaced together. Untether the cable on the negative terminal of the battery, empty the cooling system, pull out air filter housing, resonator, take out the water pump, ignition coils, high-pressure fuel pump, and disconnect the electrical connector on different sensors. Disassemble the turbocharger coolant pipes, fasteners of the heat shield, upper cover of the timing belt, and position the engine at TDC. The camshaft housing bolts should be loosened in the reversal order in which they were tightened, and the camshaft housing should then be carefully removed in relation to the cylinder head, and all remnants of the gasket sealing compound removed. Cylinder head Mark and remove the roller rocker and lifters as they occur in the cylinder head, making sure that they are re-inserted in their respective positions. In the case of camshaft sprockets, special tools should be used so as not to turn when loosening bolts and installation of new seals should also be done so as to maintain cleanliness. Installation On 2.0L (CBPA) models, proceed the same way, but make sure to align and fit correctly and to use the appropriate torque specification. In 1.8L and 2.0L timing chain models, the camshaft bearings should not be machined, but should be incorporated and have to be followed through the removal and installation steps with care, checking all the marks and alignments. Refilling the cooling system, clean and lubricate all parts, and install in the right sequence and leakage.
