RETAINER PLATE (JLG JL91471213)

A worn retainer plate can allow components to shift, leading to misalignment or mechanical failure. This aftermarket replacement part references JLG catalog number JL91471213. The retainer plate functions as a securing component that holds other parts in a fixed position. Its primary mechanical role is to prevent lateral movement of adjacent assemblies under load. If the plate fails, the resulting looseness may cause accelerated wear or sudden detachment of secured elements.
