Приводной вал тахометра Caterpillar 4W4589

A Tachometer Drive Shaft is used to transmit rotational motion from the engine's flywheel to the tachometer to measure the engine's rotational speed. It features an external spline thread that meshes with the teeth of the flywheel. As the engine's crankshaft rotates, the flywheel turns, which in turn rotates the drive shaft.Attributes:• Accommodated with Rockwell Hardness Scale value of 30N, indicating its resistance against deformation• Offers high strength and durabilityApplications:A Tachometer Drive Shaft enables the tachometer to accurately measure the engine's rotational speed which provides valuable feedback on engine performance, allowing for efficient monitoring and control of the engine's speed.
