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.
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.
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.
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.
adjust type 1 carburetor The adjustment of the carburetor will determine the behavior of the engine. There are two types of carburetors for the type 1 engine when it comes to adjustment. The old generation (up to SOLEX 30 PICT-2) with two adjusting screws and the young generation with three adjusting screws (from SOLEX 30 PICT-3), recognizable by the large screw in the carburetor housing.
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.
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 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.
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.
