finding the top dead center What does Top Dead Center (TDC) actually mean? If you study the theory of the operation of an internal combustion engine - or the "petrol engine" - it will become clear. Without going into too much detail about the theory, we have to talk about the otto cycle, better known as the four stroke cycle.
testing the coil You can easily check if the electrical voltage in the primary circuit of the coil is correct by using a multimeter. High voltage measurement at the secondary circuit cannot be performed with a standard multimeter.
radio interference Have you ever driven a classic Volkswagen with an original radio or a classic radio, then you have probably ever known the phenomenon "interference". That annoying noise, buzzing, crackling that comes out of your speakers. These disturbances can have different causes, but they can also be remedied.
spark plug codes Spark plug manufacturers use different codes to identify their spark plugs. It can be very confusing if you are not familiar with their own brand names. At the end of this article, we summarize again the coding structure, so that everything becomes crystal clear.
ignition timing - dynamic In this edition, we will adjust the ignition with the engine running, this is called a dynamic measurement. VW advises in its workshop manuals this way of adjusting all air-cooled VWs from August 1970 onwards. The static adjustment with a test bulb is then only suitable for a temporary engine adjustment on these young Volkswagens.
testing the condenser Without the condenser, the ignition will really not work properly and the contacts will burn in quickly. So it is important to measure at regular intervals if the condenser in your VW motor is still working.
measuring the coil Everyone knows that the capacitor will protect the contact points from burn-in. But what few people know is that the capacitor also plays a very important role in transforming the low voltage of the battery (6V or 12V) into a high voltage (more than 10,000V) needed to create a spark between the electrodes of the spark plug.
Engine overhaul - video 07 TDC compression in practice In video six, we explained the operation of the four-stroke internal combustion engine through animations. In this video we will look at how to determine the top dead centre of cylinder 1 in practice. We will also learn how to find the compression stroke of cylinder 1, different techniques will be shown.
replacing ignition points We will discuss how to adjust the gap between the contact points, also known as the contact angle or Dwell angle. Instead of just discussing the adjustment of the contact points, we will replace them with new ones.
Engine overhaul - video 12 the flywheel In this video, we'll explain how to disassemble and assemble the flywheel, and what tools you'll need to do so. To disassemble the flywheel, you will need to unscrew the gland nut. This nut is attached with a torque of 350 Nm, it will require some force to loosen.
