Engine overhaul - video 04 removing the distributor drive shaft We want to give extra attention in this video to the position of the distributor drive shaft of the VW Type 1 engines, . If the drive shaft of the distributor is not correctly mounted during the engine overhaul, problems can arise later with the adjustment of the ignition timing. Disassembling the drive shaft is then the only solution.
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.
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.
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.
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.
spark plug heat range The construction of the part of the spark plug that is screwed into the cylinder head determines the degree of heat. The spark plugs are screwed into the cylinder head, which is the warmest spot of the engine. Temperatures can be as high as 1000°C. The electrode part of the spark plug extends into the combustion chamber of the cylinder head.
the condenser explained The condenser is the most misunderstood part of the motor. What is inside that metal cylindrical part? So, what does this part actually do? Is it really necessary for the proper functioning of the engine? In this article we will limit ourselves to explaining what a capacitor is and what it does, and to measuring and testing the condenser.
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.
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.
checking the Dwell angle There are several devices available to dynamically measure the Dwell Angle. These are usually combined devices that measure battery voltage, Dwell Angle and advance. Others can also be used to measure the CO content of exhaust gases.
