Engine Overhaul - video 02 overhauled engines We show in this video all the engines that we overhauled for the video series. An AB 1300, an AS 1600, an AJ 1600 and a D 1200 engine, every step, every detail of the overhaul of these air-cooled Volkswagen engines will be discussed in this series.
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 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 10 the crankshaft pulley In this tenth video, we will show how to disassemble and reassemble the crankshaft pulley. We will use special tools for this, standard tools, as well as a homemade pulley puller. If you don't have the right tools and use the right technique, chances are you will warp the crankshaft pulley, you really don't want that. So watch this video carefully before you start this job.
Engine overhaul - video 11 the clutch To disassemble the flywheel, you will need to loosen the gland nut, we discuss that in video 12. But first you will need to disassemble the clutch. You can do that when the engine is on the workbench, or hanging from an engine mount. In this video we show various techniques and tools to disassemble the clutch of your Type 1 Volkswagen engine without damage.
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.
HPMX carburetors The most famous double carburettors are the Weber IDF and the Dellorto DRLA. Since a few years there is a new player on the market, namely the HPMX carburettor. This is marketed by EMPI and is also sold as a complete set, including manifolds, air filters, linkage and mounting material.
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.
air filter preheating It seems to be a natural part of your air-cooled engine, but the air filter plays a crucial role, it's like breathing in a human being. The carburettor is tasked with mixing petrol with air to deliver a flammable mixture. Petrol alone is not a good fuel. That requires oxygen and not just a little bit of it.
