What is the primary function of a crankshaft damper?

A crankshaft damper, also known as a harmonic balancer, is designed to absorb torsional vibrations that occur in the crankshaft. These vibrations can cause stress and damage to the crankshaft and main bearings over time.

What does the '6.78' and '6 Grv' refer to on this part?

The '6.78' indicates the diameter of the damper in inches. '6 Grv' means it has six grooves on its outer surface, typically for accessory drive belts like the alternator, power steering pump, or air conditioning compressor.

What is the benefit of an aluminum crankshaft damper?

Aluminum dampers are generally lighter than their cast iron counterparts. This reduced weight can contribute to slightly improved engine responsiveness and potentially reduce rotational mass.

About this part

Product Details

This is the ATI 6.78 inch aluminum crankshaft damper, part number 917071-70. It's a well-built component designed to help manage torsional vibrations from your engine's crankshaft. The damper features a 6-groove pulley system and a 3-ring design, which helps distribute the dampening forces effectively.

Constructed from aluminum, this damper is lighter than cast iron alternatives, which can be beneficial for engine response. The 3/8 inch holes are for mounting accessories or specific pulley configurations. Proper crankshaft dampening is crucial for engine longevity, as it reduces stress on the crankshaft and main bearings, especially in higher-performance applications or engines that see frequent use.
