    AI Overview
    The 4D94E-C12 piston is a standard-size, high-strength aluminum alloy component designed for the Komatsu 4D94E and Yanmar 4TNE94 diesel engines, often found in forklift trucks and construction equipment (e.g., FD20/FD25/FD30 models). These pistons are typically sold in sets including pins and rings, with a 94mm bore diameter, and are known for their application in Komatsu-Yanmar engines rather than the unrelated Caterpillar C12 engine. 
    Technical Specifications 
    • Engine Model: Komatsu 4D94E / Yanmar 4TNE94
    • Bore Size: 94.00 mm (3.70 in)
    • Stroke: 100 mm (3.937 in)
    • Type: Direct Injection
    • Material: Aluminum Alloy
    • Kit Contents: Typically includes piston, pin, clips, and rings (STD size)
    • Part Numbers: Includes YM129901-22080, YM129931-22900, YM129931-22100 
    Common Applications 
    The 4D94E piston is used in a wide range of industrial equipment: 
    • Forklifts: Komatsu FD20, FD25, FD30, FD20T-14, Clark C20D, C25D, C30D
    • Excavators/Loaders: Daewoo Solar 55V, Hyundai Robex 55-3/55W, Komatsu WA65-3, WA75-3
    • Other: Landini Trekker 60F, QAS28 Generators 
    Purchasing Options 
    • FridayParts: Piston kit with rings for ~$225.00.
    • MyMROmarts: 4-unit piston set for ~$251.02.
    • eBay: Rebuild kits (including pistons/rings) for Yanmar/Komatsu 4D94E/C12-C14. 
    Note: The 4D94E-C12 is not compatible with Caterpillar C12 engines, which have a 130.2mm bore. 
    For the best match, verify your engine serial number or piston type (direct vs. indirect injection) with the supplier, as options like 99mm or 104mm height might be required, as shown on FridayParts.
