Product Description
5408500600202 Crankshaft Signal Wheel is a pulse trigger disc installed on crankshaft for JAC QCQ23 exhaust aftertreatment matched engine. Together with crank position sensor, it generates periodic pulse signals for ECU to detect crankshaft rotation speed and angular position, controlling fuel injection timing and DPF regeneration logic accurately. This aftermarket replacement signal wheel fixes unstable engine speed, misfiring, emission fault codes and failed regeneration caused by tooth chipping, tooth wear and installation offset of old signal wheels. Precise signal feedback guarantees correct engine control strategy and keeps the vehicle compliant with emission standards for daily delivery operations.
Product Advantages Made of high-toughness alloy steel with anti-rust treatment. Evenly distributed trigger teeth are precision punched to ensure consistent signal output. The fixed keyway design prevents rotation slippage during high-speed operation. Every signal wheel passes tooth spacing inspection and dimension check before shipment, OEM contour and hole position for direct bolt-on installation.

FAQ
Q1: What fault will occur if the signal wheel teeth are damaged?
A1: The sensor picks disordered pulses, causing unstable idle speed, misfire alarm and abnormal injection timing.
Q2: Can we install the signal wheel in reversed direction?
A2: No, reversed assembly changes signal sequence and triggers serious engine starting and running failures.
Q3: What should we check before installation?
A3: Inspect the crankshaft key and keyway for wear, confirm the signal wheel sits fully against the positioning shoulder.
