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.
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 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 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 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.
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 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 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.
