OEM Manufacturing and Part Matching
This product is manufactured as an OEM replacement part. It is not described as a genuine Komatsu component. The Komatsu name and machine model are used only to identify the intended equipment application.
OEM production can be checked according to:
- Part number 21N-939-3970
- Complete Komatsu PC1250 machine model
- Equipment serial number
- Technical drawing
- Original cover sample
- Critical mounting and connection dimensions
If the original part has been replaced or modified previously, we recommend sending the old cover or a complete dimensional drawing before production.
Important Quality and Dimensional Checks
The cover must match the corresponding equipment assembly accurately. Important inspection points include:
- Overall dimensions
- Mounting surface dimensions
- Bolt-hole pattern and position
- Internal and external clearances
- Machined surface condition
- Surface treatment
Final material, production process, heat treatment and surface finish will be confirmed according to the sample, drawing and order requirements where applicable.
Why Correct Fitment Matters
Using an incorrectly matched cover may result in:
- Bolt holes failing to align
- Poor contact between mounting surfaces
- Oil leakage or contamination risk
- Abnormal vibration or noise
- Repeated disassembly and equipment downtime
Part number verification should therefore be combined with machine information and dimensional confirmation.
