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.
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.
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 overhaul - video 16 part 1 valves removal In this first part of video 16, we disassemble cylinder head valves and valve springs. In the first part, we start by demonstrating the tools and techniques used, and disassemble the valves of a relatively new cylinder head.
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 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 diagnostics - video 04 part 1 valves and valve springs In video 16 of the engine overhaul series, we disassembled the valves and valve springs.
Not all of the cylinder heads we showed were in good condition, this does not mean that all parts need to be replaced. After a thorough diagnosis, it will show if the valves and valve springs are still reusable. This video discusses valve and valve spring diagnosis. It consists of four 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 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.
fuel circuit - concept The combustion engine of our air-cooled Volkswagen uses a mixture of petrol and air. It is extremely important that both the amount of air and the purity of the air are regulated, this also applies to the petrol. Unfortunately, the petrol circuit is not very well known to enthusiasts and it is not always well maintained.
