That metallic “tick-tock” that occurs primarily in motor cars of essence -and it is even more visible in the models of high performance – it is actually a metallic sound that is produced for the result of two phenomena, for on one side the of thermal expansion and for the other, the of static friction.
What is a dumper? It is a cylindrical tool made of steel, which offers greater resistance to shocks. The central part is roughened to improve grip. It is manufactured in different sizes, from a lower range of 1 mm to 10 mm.
What happens if the tappets make noise in the car? Also called dumpers. When you start the car, the noise produced by tappets is usually a clicking sound produced by lack of lubrication. something very common when the engine is cold, and it gets worse Yes they were left standing for several weeks (days on some models).
What is the function of the tappets of an engine? How it works the dumper? The pusher or dumper rotates and at the same time pushes, adjusting the movement of the camshaft to the needs of the engine at different times. The set of pegs in one the car works transmit the movement of the cams to the valves.
How to eliminate the noise of the pushers? As soon as the metallic knocking sound becomes noticeable, HYDRO-STÖSSEL-ADDITIV must be added to the oil. After adding product, start vehicle until engine warms up.
What types of dumpers are there? There are of them types Tackle or dumpers: in the first place the mechanics and, secondly, the hydraulics. The difference between each of them is the Kind of the block in which they are to be installed.
