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.
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.
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 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 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.
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.
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.
Engine overhaul - video 14 rockers and pushrods In this video we will show how to disassemble and reassemble the rocker arms and pushrods. We will discuss the diagnosis of the rockers and pushrods in our other video series, which deals with engine diagnosis. How to adjust the rockers, an action also known as shimming, can be seen in our video series on engine adjustment.
Engine diagnostics - video 01 crankshaft end play In the first video of this new series, we will look at how to measure the crankshaft end play. Measuring the crankshaft end play, will help you estimate if your engine needs a total overhaul. If the result of the measurement is greater than or equal to 0.15 millimeters, then the crankshaft clearance is too large, and a total engine overhaul is recommended.
