Available again! We've located a limited number of these OEM Crankshaft Pulleys through one of our overseas suppliers. Nissan has discontinued them, so make sure to get yours before they are gone again!

Includes:

(1) Crankshaft Pulley

Description:
Crankshaft pulleys, also known as harmonic balancers and crank dampeners, protect L-Series engines by absorbing damaging vibration that occurs when the engine is running. Inline engines produce more vibration from running than their V counterparts, making the job of the crank pulley even more important on early Z-Cars. The rubber portion of a crank damper is prone to wear, which can lead to increased engine vibration and movement in minor cases and reduced accessory function or engine damage in extreme cases. This is the genuine, original equipment (OEM) replacement pulley. Don't forget to inspect your belts and other pulleys when inspecting your dampener!

Application Note:
Timing indicators were matched to the crankshaft pulley during original engine assembly. This dampener is designed to work with the March 1973 and later version, which is when Nissan moved the timing marks from the pulley to the indicator on the timing cover. The pulley has a single timing mark to work with the indicator, which was located on the driver's (left) side of the cover. If your 1973 model has multiple marks on the pulley and a single pointer toward the passenger side of the cover, please contact us for options.

Alternative Option:
If your engine setup only uses a fan belt, you may want to consider one of our performance harmonic dampers instead of the stock type pulley (see Related Items).
