It produces, however, a disagreeable noise. As a rule, idle gear clatter will not damage the gears, as almost no torque is transmitted at low speeds or when idling. This type of gear clatter increases with the specific output of the engine, the reduction of moveable engine masses and a diminished idle speed. The phenomenon is due to irregularities during the ignition and combustion process which occur at low engine speeds. Gear clatter at idle may occur when there are low numbers of revolutions per minute. This gear clatter under load may damage the gears. These may incite natural frequencies of the drive unit to such an extent that tooth flanks separate off and clatter despite their load from the torque. It is caused by design factors, such as number of cylinder, number of propeller blades, engine speed, and number of gear teeth. Gear clatter under load may occur at a specific RPM. Such influences are beyond the control and responsibility of transmission manufacturers.Ī distinction should be made between gear clatter under load and idle gear clatter: The possibility of tooth flanks to separate is due to the backlash required for compensating tolerances and thermal expansion to ensure the operational safety of the transmission.Īs a rule, gear clatter is the result of an unfavorable interaction of individual components, such as engine, couplings, gears, propeller shaft, and propeller. This is caused by irregularities of torque and of rotation. Gear clatter occurs when the tooth flanks in the transmission separate and hit each other again in actual operation. » to this answer Do I need to replace my oil cooler or drive plate? Transmissions last the longest at steady cruising speeds and with no high-rpm shifting. Avoid idling for great lengths of time as this puts extra wear on the transmission. Noise may be more apparent at idle, since the engine firing impulses are further apart. With a bad drive plate, even the slightest variation in firing impulses from the engine can cause transmission noise. This plate absorbs the engine's firing impulses, is the last link between the engine and transmission, and connects directly to the transmission's input splines. If the engine is tuned up and running well, the drive/damper plate may be the cause of noise. If compression is not within 10% in all cylinders, uneven firing impulses may cause the transmission to make backlash noise. A compression check is a must before putting any blame on the transmission.
