PLATE-LOCK (Hyster HY159143)

A damaged lock plate can allow unintended movement of a secured component, leading to operational instability. The Hyster catalog reference HY159143 identifies this aftermarket replacement part. A lock plate functions as a mechanical barrier that prevents loosening or disengagement of a fastener or assembly. When a lock plate fails, the resulting slack can cause misalignment or accelerated wear of adjacent parts. During routine service, a worn lock plate may not hold its intended position, compromising the security of the connection. Verify the serial number or application, then call (562) 693-7748. This part is listed as a plate-lock in the aftermarket category.
