Engine adjustment - video 02 adjusting the rocker arms In the first video of this series, we adjusted the valve clearance. In addition to the valve clearance, the position of the rocker arm relative to the valve stem, is also a very important setting. If a rocker arm is not positioned correctly, it can be adjusted, which is called shimming.
air filter thermostat The preheating of the fresh air supplied via the air filter to the carburettor is a part of our VW engine that gets too little attention. This system will ensure that in all weather conditions the carburettor is supplied with air at the right temperature. With these younger air filter models you don't have to adjust anything in contrast to the older models.
Engine overhaul - video 06 find the TDC compression stroke We will explain in this video how to determine the top dead center, as well as which of the two top dead center moments is this one from the compression stroke. This is important in order to properly position the distributor drive shaft. Properly understanding how a four-stroke engine works is essential when you begin an engine overhaul.
mixture preheating The engine is stopped as a result of poor combustion. This bad combustion is often caused by a, at that moment, wrong composition of the fuel in the cylinders. Because of this bad combustion, the engine does not deliver the desired power and you can feel this in the form of stuttering of the engine.
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.
Engine overhaul - video 15 disassemble cylinder heads In this video, we will show how to disassemble the cylinder heads of a VW Type 1 engine, and what challenges you may face.
Engine Overhaul - video 01 video series preview In this video, we will give an overview of the most important steps during the engine overhaul of a type 1 air-cooled Volkswagen engine. Each step will be discussed in a separate video. We will show special tools and even homemade tools to help the enthusiast perform their engine overhaul.
Engine adjustment - video 01 valve clearance The valve clearance is the first thing to check when adjusting an engine. If the valve clearance is not adjusted properly, then adjusting for example, the ignition, or the carburetor, will do little good. In this video we will show you how to adjust the valve clearance.
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 diagnostics - video 02 BONUS defective rockers arm parts In video two of this series, we measured the rocker arm parts, and compared them to the wear limits listed by the VW workshop manual. In this video, we will show examples of rocker arm parts that are in less good condition than these of our AB 1300 engine from video two. This should help, to better diagnose the rocker arm parts.
