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 16 part 2 valves removal In Part 1, we showed the basic techniques for disassembling the valves and valve springs. We did this on a fairly new cylinder head.
When you`re dealing with a used cylinder head, disassembly may be a little less smooth.
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.
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 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.
Engine diagnostics - video 03 pushrods In video fourteen of our series on engine overhaul, we disassembled and reassembled the rocker arms and pushrods. In this video, we will inspect the pushrods. The result of this diagnosis, will tell us if we can reinsert the pushrods, or if we need to replace them.
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.
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.
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.
