Retainer washer for Kawasaki K3VL112/B-1NR MM-PO

The retainer washer 424-4202 serves as a mechanical fastener within the internal assembly of hydraulic pumps. Its primary function is to maintain the axial position of critical components such as bearings, gears, or seals, preventing unwanted movement that could lead to misalignment or mechanical interference during operation. By holding these parts securely in place, the washer ensures that the internal clearances of the pump remain within specified tolerances.

This component is designed specifically for the Kawasaki K3VL112/B-1NR MM-PO axial piston pump. In this hydraulic system, the washer is used to stabilize internal elements, helping to maintain the integrity of the hydraulic flow and the mechanical alignment of the rotating group. Proper installation of this retainer is necessary to ensure the pump functions as intended under operational loads.

Retainer washers are used throughout hydraulic machinery to lock components onto shafts or within housings. They provide the necessary tension or physical barrier to resist axial forces and vibrations that occur during the operation of heavy equipment. By securing these parts, the washer helps prevent the shifting of internal pump elements that could otherwise result in increased friction or accelerated wear of the pump internals.
