  Q: What precautions should be taken when removing the Timing Chain, Timing Chain Tensioner and Timing Cover for Four-cylinder engines on Volkswagen Rabbit?

  A:

  Special care should be taken to ensure that the crankshaft or Camshafts are not turned individually as the timing chain is disconnected since it will cause damage to the valves. In case the battery is switched off, a number of systems will have to be re-learned to be used properly. This is a process peculiar to the CCTA and CBFA engines. To remove the upper timing chain cover, the engine cover and oil dipstick tube should be first removed making sure that the O-ring at the bottom of the dipstick tube is changed. The charge air pipe is supposed to be moved aside with the disconnecting of the required components provided it is equipped with a noise generator. Coolant hoses should be forced back, electrical connector to the camshaft adjustment valve should also be disconnected and then the valve and seal should be removed and replaced. Removal of the upper timing chain cover is then done in a star fashion and the gasket has to be discarded and replaced. To install, one should first clean the cover and the Cylinder Head faces, then to install a new gasket then tighten the cover in that order. Lower cover removal This includes disconnection of battery, lifting up of the vehicle and removal of several parts such as the splash shield, engine cover and inner fender liner and emptying of the engine oil as well as the air charge pipe. Crankshaft pulley should be handled carefully to avoid its damage and engine should be placed in support to have additional disassembling. Oil dipstick tube and turbocharger components should be disconnected and then the lower cover can be removed. Installation involves cleaning of surfaces, putting on RTV seals and alignment of timing marks. The timing chain and tensioners should be maintained with care so as not to cause dire engine harm and the entire parts are to be reassembled in the same sequence of their removal making sure that the crankshaft is turned by hand to ensure that it does not meet any resistance and only then the engine is started. The balance shaft timing chain and tensioner are also to be installed taking care; the tensioner is to be thread locked with sealer and installed.

  Q: How to replace the Oil Pump, Timing Chain and Timing Chain Tensioner on Volkswagen Rabbit?

  A:

  Oil pump cannot be serviced and has to be changed in case of any issue. First, you want to take the engine off and detach the transmission to the engine. The next step is to remove the upper oil pan and oil pick-up tube and the Crankshaft front oil seal flange. Slacken the sprockets on the camshaft and take out the control housing. Cut off the tensioner piston of the oil pump using a screwdriver and inserting a pin. Take out the tensioner mounting fastener and move the tensioner assembly, chain guide, and tensioner guide off the dowels on the cylinder block making sure that the pin does not come out. When you are holding the oil pump drive sprocket, take out the sprocket retaining bolt and then take out the sprocket and chain. Then remove the oil pump that is holding fasteners, the oil pump and O-ring and put in a new O-ring. The crankshaft should be locked in the TDC position and a new O-ring on the pump fitted, then the pump should be fitted, and the retaining fasteners hand tightened. Install the oil pump sprocket by inserting the lettering outward and affix the sprocket retaining bolt and tighten the sprocket to the recommended torque. Slide the oil pump bolts to loosen, and use the VW special alignment tool to reach a point where the ole oil pump sprocket is centered in line with the crankshaft sprocket, but with the special shim in place in 2011 models. Install the tool on the crankshaft and insert the tool mounting bolts. Move the oil pump sprocket towards the tool and rub it against the magnets until they are clean. Take off the crankshaft lock pin and tap the crankshaft in the direction of the front using a shim or a screwdriver. Lightly press the body of the oil pump against the side of the oil pump chain, and tighten the retaining bolts to the required torque. Once more lock the crankshaft in the TDC position and remove the special alignment tool. When a new pump is fitted, pour oil in the pick-up tube hole as the sprocket of the oil pump is rotating. Insert the oil pump chain on the sprockets and also make sure that it flows straight between two sprockets. Install the upper oil pan, and install the chain guide, tensioner guide and tensioner assembly to the cylinder block dowels; tighten the tensioner fastener to the recommended torque. Take out the pin in the tensioner and unlock the piston in order to hook up the chain guide. The rest of the installation is done in the opposite sequence of deletion.
