FAQ

Q1: Will this piston fit my Isuzu 3kb1 engine used in a Sumitomo SH200 excavator?
Yes, the 8944113881 piston is a direct OEM replacement for the Isuzu 3kb1 engine, which is commonly installed in Sumitomo SH200 and similar excavator models. We recommend cross-referencing your engine serial number with the part number 8-94411-388-1 to confirm compatibility.

Q2: What is the recommended installation procedure for this piston?
Installation should be performed by a qualified diesel mechanic. Ensure the cylinder bore is within service limits and honed correctly. Lubricate the piston skirt and rings with clean engine oil before assembly. Use a ring compressor to avoid ring breakage. Torque connecting rod bolts to manufacturer specifications (typically 50-60 Nm + angle).

Q3: How do I identify a genuine Isuzu piston from a counterfeit?
Genuine parts like this 8-94411-388-1 feature precise laser-etched part numbers, a smooth anti-friction coating, and consistent weight. Counterfeits often have rough casting marks or mismatched dimensions. Our pistons come with a traceable batch number and certificate of analysis upon request.
