Product Overview

The 198-61-11250 BOLT is a genuine Komatsu OEM replacement bolt.

When to Replace

• Threads show signs of stretching, galling, or corrosion damage
• The bolt head has been rounded by improper wrench use
• Visible pitting or rust that reduces the bolt's effective load-carrying area
• The bolt was designated as a single-use fastener in the Komatsu service documentation
• Any bolt removed from a safety-critical or high-load application should be carefully inspected

Installation

1. Clean the threads — use a thread chaser on both the bolt and tapped hole
2. Apply the specified thread locker if required by the service procedure
3. Start by hand — never use a wrench to start a bolt; it should turn freely for several threads
4. Tighten in stages if the torque specification is high — 50%, then 80%, then full torque
5. Use a calibrated torque wrench — proper bolt tension depends on accurate torque
