2312035701 Hyundai / KIA SPROCKET-CRANKSHAFT, Price: 22.93$, Weight: 0.51kg

Crankshaft Timing Gear for Hyundai/Kia Engines ⚙️

This precision steel gear mounts on the crank nose and drives the timing belt, keeping pistons and valves in perfect sync. A correct tooth profile, hardened surface, and tight keyway fit ensure stable timing and long belt life. Designed to work with OE tensioners and cam sprockets, it maintains smooth power delivery and clean idle.

Why you need it ✅

Age, rust, or belt wear can round teeth or loosen the keyway. That leads to belt slip, noisy operation, and drifting ignition timing. Replacing the worn gear restores accurate valve timing and prevents costly damage.

How it works

The crank turns this toothed gear, which moves the timing belt and spins the camshafts at a 2:1 ratio. Proper alignment of timing marks and a snug fit on the crank key keep the engine synchronized under load.

If it fails ⚠️

Expect rough idle, loss of power, misfire, no-start, or check engine lamp. Severe slip can bend valves on interference engines. Metal dust near the belt area and P0335-type sensor errors may appear.

Pro tips ️

Always replace belt, tensioner, and front crank seal together. Clean the crank snout, inspect the key, align marks carefully, and torque to spec—never hammer the gear on.
