JE1005901BB Crankshaft Key is a precision locating component for JAC JE493ZLQ6M diesel engine crankshaft. It fits into the key grooves of crankshaft nose and crank pulley, transferring torque while fixing the relative angular position to guarantee accurate timing alignment. This aftermarket replacement key resolves timing deviation, pulley slipping and abnormal belt jumping caused by sheared, deformed or worn crankshaft keys. Accurate positioning keeps injection timing correct and avoids valve-piston collision risk for light trucks used in urban delivery and variable-load freight operations.
Product Advantages Made of high-strength alloy steel with quenching treatment, offering excellent shear resistance and wear resistance. Precision machined dimensions ensure tight fit inside key slots without loose clearance. Standard woodruff key profile matches OEM keyway perfectly. Each crankshaft key is inspected for size and surface defects before shipment, easy to install during timing gear or crank pulley assembly.

FAQ
Q1: What fault will occur if the crankshaft key is sheared off?
A1: Crank pulley loses fixed position, timing jumps, leading to power loss, black smoke and even serious engine collision damage.
Q2: Can we reuse a slightly deformed crankshaft key?
A2: No. Hidden crack and reduced strength may cause secondary breakage under torque impact.
Q3: What to check before installing the new crankshaft key?
A3: Inspect key grooves on crankshaft nose and pulley for burrs, deformation or excessive wear.
