6 volts and 12 volts Until the early 1970s, the VW Beetles were equipped with 6 volts in their 1200 cc version. The 1300 cc Beetle was first equipped with a 12 volt system in 1968. The VW Bus and type 3 VWs were increased to 12 volts in 1967. Types 4 are in 12 volts, as they were only introduced to the market in the late 1960s.
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.
ignition timing - static In air-cooled Volkswagens from August 1970, the notch in the crankshaft pulley is used to dynamically adjust the ignition timing. The static adjustment with the test lamp is then only suitable for temporary adjustment on younger models.
Engine overhaul - video 08 ignition time of cylinder 1 In this video we will determine the ignition timing of cylinder 1. This mark will be needed to correctly position the distributor drive shaft during assembly, as well as for ignition advance adjustment once the Type 1 Volkswagen engine is rebuilt.
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.
the distributor The intention is that we can adjust the ignition of our classic Volkswagen ourselves. First you have to know which parts have an influence on the operation of the ignition and you have to understand how the ignition circuit works, this is very important to be able to make a good diagnosis and to be able to adjust the ignition later on.
voltage drops The electric consumers of your classic Volkswagen expect the full 6 volts or 12 volts (or more) to function properly, which is unfortunately not always the case. Especially the 6 volt version sometimes complains about slow running windscreen wipers, weak headlights and direction indicators that pinch too slowly.
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 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.
Engine overhaul - video 13 replacing the crank seal During a complete engine overhaul, you will need to replace the crank seal. But replacement may also be necessary, when you discover an oil leak behind the flywheel, which will impair the operation of the clutch. We show in this video how to disassemble and reassemble the crank seal.
