Er nøyaktig samme lyden på tomgang jeg har og, som du linket. Identisk.
Men les dette, som jeg fant på nett etter et kjapt søk:
"The issue with gear rattle is that conventional lightweight flywheels retain the car's original solid-hub clutch disk. First, the lightened flywheel has less mass to damp the power pulse variations. Second, there is no mechanism within the solid-hub clutch disk to absorb the power pulse variations. The result is that a conventional lightweight flywheel with solid-hub clutch may create a noticeable amount of rattle. There is simply no cushioning action at all. Note that this gear rattle only occurs at idle, in neutral, with the clutch let out. It is not heard at any other time. Above idle (even just a couple hundred rpm) and the increased frequency of power pulses outpaces the speed at which the components couple/de-couple, therefore no rattle whatsoever.
So how to have the best of both worlds? Simply use the correct style of clutch disk for the flywheel in use. If using a lightweight single-mass flywheel, the answer is to use a sprung-hub center clutch disk. The sprung-hub center setup damps out the majority of the power pulse variations, resulting in little to no rattle. Due to the frequency of the power pulses, slowing down the engine slightly more at idle by turning on the A/C and loading up the alternator with headlights and other electrical draw may increase the amount of residual rattle. A change to a slightly heavier grade of transmission fluid (UUC recommends a specific mix of transmission fluids, 1 bottle Redline 75W-140NS and 1 bottle Redline D4 ATF) will eliminate it entirely in some cars, or at least reduce the remaining rattle a subjective 90%."
