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.
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.
Engine overhaul - video 05 install the distributor drive shaft This is the continuation of video 04, we are now going to install the distributor drive shaft, both on an already rebuilt Volkswagen Type 1 engine and on a split Type 1 crankcase. We pay a lot of attention to the correct positioning of the drive shaft at the beginning of this video series, because it is crucial to be able to adjust the ignition properly, later, when the engine is overhauled.
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.
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.
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.
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.
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.
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.
