Product Features & Applications

Heavy-duty Front Idler Assembly for Komatsu PC400-5, -6, -7, and -8 excavators. Fully compatible with OEM part numbers 208-30-00100 and 208-30-00401. Engineered with high-strength alloy steel and precision-hardened surfaces, our Idler Groups are built to withstand extreme impact and provide superior track tensioning for maximum machine stability.

Product Overview

The Front Idler is a critical component of the Komatsu PC400 undercarriage, responsible for guiding the track chain in and out of the track rollers and maintaining proper track tension. Our idlers are designed specifically for the demanding 40-ton class machines, ensuring consistent performance in mining, quarrying, and heavy construction environments across the PC400 Dash 5, 6, 7, and 8 series.

Key Features & Benefits

  • Broad Compatibility: Fits the entire Komatsu PC400 range, replacing OEM parts 208-30-00210, 208-30-00230, and more.
  • Superior Casting/Welding: Use of high-quality 35SiMn or 40Mn2 steel ensures excellent structural integrity and fatigue resistance.
  • Advanced Induction Hardening: The tread surface is hardened to HRC 50-56 with a depth of up to 10mm, drastically reducing wear from abrasive rocks and sand.
  • Reliable Sealing Technology: Features professional-grade bi-metal bushings and heavy-duty floating seals to prevent oil leaks and protect against internal contamination.
  • Shock Absorption: Optimized design to better distribute impact loads, protecting the recoil spring and other undercarriage components from damage.

Why Trust Our Undercarriage Solutions?

For heavy machinery like the PC400, a failed idler means expensive downtime and potential damage to the entire track group. We perform ultrasonic inspections and hardness mapping on every idler we produce. Our goal is to provide a mining-grade alternative that delivers the same durability as genuine Komatsu parts but at a more competitive price point, backed by a comprehensive warranty.
