Komatsu Part SEAL RING 07018-31054

—

Product Overview

The 07018-31054 SEAL RING is a genuine Komatsu OEM replacement seal ring. Seal rings create a leak-tight barrier between components in your machine's hydraulic and drivetrain systems — sealing rotating shafts, pistons, or housings against pressurized fluid escape and contamination ingress.

When to Replace

• Pressurized fluid leaking past the seal ring — visible at the shaft exit or housing interface
• The ring material is worn, cracked, or has deformed from heat and pressure cycling
• Cuts, nicks, scoring, or surface damage visible on the ring
• The component was disassembled for service — seal rings should be replaced whenever the assembly is opened
• Metal particles found in the system oil — seal ring wear can produce debris that contaminates the fluid

Installation

1. Confirm 07018-31054 matches your Komatsu parts catalog listing for your model
2. Clean the groove and mating surfaces thoroughly — trapped debris prevents proper sealing
3. Lubricate the seal ring with clean system fluid or assembly lubricant before installation
4. Install in the correct orientation — some seal rings have a directional profile that must face the pressure side
5. Check for leaks after the system reaches operating pressure and temperature
