The machine serial number (VIN or chassis number) is the only reliable way to confirm 8A31-54-1140 applicability for your specific unit. Komatsu serial numbers encode the model family, production year, and build specification, including market-specific variants that may use different part numbers for the same installation position.
Serial number location: stamped on the frame rail (typically right-hand side, near the front axle), on the identification plate in the cab, and in the machine documentation. Format varies by model: typically an 8–17 character alphanumeric code. Provide this number when ordering 8A31-54-1140 to receive written confirmation of applicability.
Our parts team maintains Komatsu parts databases for all major model families and can confirm 8A31-54-1140 applicability from your serial number within one business day.
Part number 8A31-54-1140 may have been superseded in recent Komatsu catalog editions. Supersession means the OEM has released a revised or improved replacement. The supersession number directly replaces 8A31-54-1140 and should be used for all new orders — older and supersession numbers describe the same installation position.
To verify current supersession status, consult the Komatsu electronic parts catalog (EPC) for your machine serial number, or ask our parts team to confirm the current valid number. Ordering a superseded number is typically accepted — distributors automatically supply the current valid equivalent.
