What is the primary function of a crank hub?

The crank hub is the component that attaches the crankshaft pulley to the front of the crankshaft. It's essential for driving accessories like the alternator, power steering pump, and air conditioning compressor, as well as the timing belt or chain.

Why is steel a good material for this crank hub?

Steel offers a strong and durable material choice for a crank hub, especially in performance applications. It can withstand the rotational forces and potential stresses from higher engine speeds and accessory loads without deforming.

What does '8mm HTD Pulley' refer to?

HTD stands for High Torque Drive. The '8mm' refers to the belt pitch, which is the distance between the centers of the teeth on the belt. An 8mm HTD system is designed for higher torque transfer compared to smaller pitches.
