How to Decode IHI Excavator Serial Numbers and Model Codes:
1. Locate the serial plate on the right undercarriage frame.
2. Parse the model prefix (e.g., IS50U = 5-tonne mini excavator; V4 = compact series; NX = modern Sumitomo line).
3. Check suffix (-2/-3 = generation; extract year from stamped digits).
4. Match to specs for OEM-compatible parts like Track Rollers from AFT Parts Canada.

What Do IHI Excavator Model Numbers Mean?
IHI model numbers break down into prefixes, numbers, and suffixes indicating size, series, and generation. IS denotes IHI Standard series for mini excavators; the number like 50 represents 5-tonne class; U means upgraded canopy version. V4 signifies 4th generation compact models (3–5 tonne), while NX marks next-generation Sumitomo-IHI hybrids post-2015 for heavier duty. This helps Canadian contractors in Alberta mining select precise undercarriage parts.
Where Is the IHI Excavator Serial Plate Located?
The primary location is the right side of the undercarriage frame on a 3–4 inch stamped metal plate, visible without disassembly. For older V4 models, check the engine compartment or cab frame. Canadian operators in wet BC sites or Quebec forestry should clean mud and debris first to avoid reading errors and downtime.
How Do You Decode an IHI Serial Number Step-by-Step?
Step 1: Read the full string like IHIS50U2XXXX, separating model from production sequence. Step 2: Extract manufacturing date from middle digits (e.g., 05=2005) using Sumitomo-IHI charts. Step 3: Verify generation for parts compatibility, such as reinforced Idlers for -3 upgrades. AFT Parts Canada offers OEM-spec matches for seamless fit in Ontario rentals.

What Are Common IHI Model Examples Like IS50, IS55, V4, and NX?
IS50U-2 (pre-2008, lighter tracks) differs from IS50U-3 (post-2008 zero-tail swing for tight Ontario sites). V4-series like V4-55 (5.5t) suits rubber pads in urban work. NX-series such as NX55 (2015+) features enhanced sprockets for Saskatchewan aggregates, ideal for mixed fleets with Komatsu or Hitachi.
Which Undercarriage Parts Fit Specific IHI Models?
Match by serial: IS and V4 models use single-flange Track Rollers; NX requires sealed bearing Carrier Rollers.
