—

Product Overview

The 56D-50-13171 PACKING is a genuine Komatsu OEM replacement packing from the 56D prefix series. Packings are sealing elements used in hydraulic cylinders, pumps, valves, and other pressurized components — they prevent internal and external fluid leaks while withstanding the pressure, temperature, and speed conditions of hydraulic operation.

When to Replace

• Fluid leaking past the packing — internal leakage causes performance loss; external leakage is visible at the shaft or housing
• The packing material is hard, cracked, or has taken a permanent set — it no longer conforms to sealing surfaces
• Cuts, nicks, or extrusion damage visible on the packing lips or body
• The hydraulic component was disassembled for any service — packings must always be replaced during overhaul

Installation

1. Confirm 56D-50-13171 in your Komatsu catalog
2. Clean the groove and sealing surfaces — old packing fragments must be completely removed
3. Lubricate the packing with clean hydraulic oil before installation
4. Seat to correct depth and in correct orientation — packings often have directional lips
5. Check for leaks after system pressurization
