Machine Coverage & Configuration Breakdown

This parts catalog provides full structural coverage for the Sumitomo SH250-6 and its extended-front counterpart, the Sumitomo SH250-6LR. Operating conditions demand exact component matching, and this manual catalogs all variations between standard excavators and super long reach platforms, including counterweight mass variations, dedicated long-reach revolving frames, boom and arm cylinder hydraulic dampening lines, reinforced undercarriage guarding, and extended-reach front-end work equipment. Additionally, serial-number cutoff points are precisely detailed throughout each section (such as parts transitions at 250N6-1105, 1106, 1108, 1109, and 1111), guaranteeing that mechanics and parts specialists obtain the exact revision of every bracket, seal kit, valve, or hydraulic line required for their specific machine build.

Part Number Structure & Interchangeability Coding

To ensure total ordering accuracy, this catalog utilizes Sumitomo’s standardized composition and interchangeability system:

IMAGES PREVIEW

• Composition Hierarchy (COMPO): Denotes the structural relationship between parent assemblies and child parts. Items marked 1 or 1A represent complete parent assemblies (such as a complete track roller, main control valve, or swing motor), while items marked 2, 2A, 3, and 4 identify the internal replacement components, seals, shafts, and hardware nested within that assembly.
• Interchangeability Symbols (ICA): Guides parts staff when updating or substituting part numbers across serial production breaks:
  • = (Equal): The listed replacement part is fully interchangeable in both directions with the prior part number.
  • < (Substitute): The new replacement part number can substitute for the earlier part, but the older part cannot be substituted into newer machines.
  • X (Non-interchangeable): Parts are distinct and cannot be substituted for one another under any circumstances.
• Service Quantities: Accurate part counts (Q’TY) are specified for each subassembly, with bulk or adjustable items marked as AR (As Required), such as leveling shims and harness bands.

Essential Capability, Maintenance Value & Instant Delivery

The Sumitomo SH250-6 and SH250-6LR Hydraulic Excavator Parts Catalog Manual is an indispensable asset for heavy equipment owners, independent repair contractors, and authorized dealerships. Having access to genuine exploded diagrams and factory part numbers allows technicians to disassemble complex units with confidence, verify the correct orientation of thrust washers and internal seals, identify missing or worn hardware, and ensure replacement parts fit on the first attempt.

Misidentifying a hydraulic seal, ordering the incorrect track link pitch, or confusing standard backhoe lines with long-reach hydraulic plumbing leads to costly machine downtime, unnecessary restocking fees, and delayed job completions. This catalog guarantees that you reference the exact factory part numbers assigned to your excavator’s specific serial range.

Delivered as an instant PDF download immediately upon checkout, this manual requires no waiting for physical shipping and no risk of shop grease ruining an expensive paper book. Store the file securely on your desktop, laptop, tablet, or smartphone for immediate lookup in the workshop or out in the trench, or print out crisp, high-resolution pages for greasy hands on the job site.
