Komatsu Part WASHER 01643-31645

—

Product Overview

The 01643-31645 WASHER is a genuine Komatsu OEM replacement washer. Washers distribute the clamping load of a bolt or nut over a larger surface area, prevent the fastener from embedding into softer material, protect the component surface from galling during tightening, and in the case of spring washers, resist loosening caused by vibration.

When to Replace

Replace the 01643-31645 when the washer is deformed, crushed, or cracked; when spring washers have flattened and lost their spring force; when corrosion or pitting is visible on the washer surfaces; or when the fastener has been removed during service — always inspect washers before reuse.

Installation

1. Clean the washer and all contact surfaces
2. Position the washer correctly — under the bolt head or nut as specified
3. Tighten the fastener to the specified torque — the washer's thickness must be accounted for in the joint stack
