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.
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.
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 09 the fuel pump We will disassemble and reassemble the mechanical fuel pump from a VW Type 1 engine with carburetor in this video. The electric fuel pump is discussed in another video. The fuel pump pushrod and the fuel pump flange get extra attention in this video.
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.
Engine overhaul - video 03 the workshop We show in this video what the possibilities are to work on your VW engine. If you plan to overhaul several engines, then buying a professional engine stand is recommended. If you only want to overhaul the engine of your own classic Volkswagen, then buying special tools is not cost effective. We will show all options.
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.
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 diagnostics - video 04 part 2 valves and valve springs In the second and third parts of this video, we will measure valve spring pressure. We begin in part 2 by measuring the valve spring pressure at open valve. Also known as the valve spring pressure at maximum valve lift. In part 3, we will measure the valve spring pressure at installed length.
