D275 BULLDOZER FRONT IDLER WHEEL — GENUINE OEM UNDERCARRIAGE COMPONENTS

D275 Front Idler Wheel (Guide Wheel) — OEM Undercarriage Replacement Part

Origin Machinery is a dedicated manufacturer of crawler undercarriage components with more than ten years of field-proven expertise, operating an integrated production base of 230,000 m² with three specialized plants and an annual capacity exceeding 100,000 undercarriage sets. We supply the D275 front idler wheel — also known as guide wheel or track idler — as a direct OEM replacement for Komatsu D275-series bulldozers. Positioned at the front of the track frame, the idler maintains correct track tension and guides the track chain, directly influencing undercarriage stability and service life under continuous heavy load. Each unit ships with the matched shaft and mounting collar for straightforward on-site fitment.

D275 Bulldozer Front Idler Wheel

Technical Specifications

  • Compatible Model: Komatsu D275A / D275AX series bulldozers
  • Part Type: Front Idler / Guide Wheel (Track Idler)
  • OEM Reference: 17M-30-01310, 17M-30-00311
  • Wheel Body Material: 50Mn forged alloy steel (integrally forged)
  • Surface Hardness: HRC 48–52 after integral heat treatment
  • Bearing: High-strength bimetal (steel + copper) sliding bushing
  • Sealing: Floating seal assembly with vacuum oil filling
  • Finish: Anti-corrosion primer; custom topcoat available

Key Features & Advantages

  • Integrally Forged Wheel Body: Round steel is induction-heated, upset and forged as a single body, then friction-welded — providing high structural strength and fatigue resistance under repeated shock loads.
  • Deep Heat Treatment: Spray quenching and overall heat treatment produce a hardened wearing surface (HRC 48–52) with a tough, shock-resistant core; the outer diameter is precision-turned for accurate track engagement.
  • Bimetal Bushing: A steel-outer / copper-inner composite bushing reduces friction and wear at the bearing interface for longer service life.
  • Floating Seal & Vacuum Oil Filling: Metal-ring plus rubber floating seals prevent lubricant leakage under high temperature and pressure; vacuum oil filling and airtightness testing guarantee long-term sealing performance.
  • CNC-Machined Sealing Surfaces: Tight-tolerance bore and seal seats block mud and contaminant ingress in muddy, high-load conditions.
  • Verified Reliability: 100% magnetic-particle inspection for cracks and a run-in test under simulated load detect abnormal noise or oil leakage before shipment.

Manufacturing & Quality Control

Origin Machinery runs an intelligent manufacturing system across forging, CNC machining, heat treatment, assembly and coating. More than 40 flexible production lines — including German five-station automatic hot-forging, heat-treatment and friction-welding lines — are coordinated through MES, PDM, SAP and SCADA for real-time process control and full traceability. A complete in-house laboratory performs raw-material spectroscopy, metallographic analysis, hardness and three-coordinate measurement, plus crawler fatigue and floating-seal endurance testing, so every lot is verified before it leaves the plant.
