FAQ

Q1: Is this piston compatible with both the D4BB and 4D57 engine models?
A: Yes, this piston (23410-42202) is designed to fit both Hyundai D4BB and 4D57 diesel engines. However, we recommend checking your engine’s serial number and comparing the piston diameter, pin bore size, and compression height to ensure a perfect match.

Q2: Does this product include the piston rings, or is it just the piston and pin?
A: This listing is for the piston with pin assembly only. Piston rings are sold separately unless otherwise specified. For a complete rebuild, we recommend ordering matching rings and liners for your engine model.

Q3: What is the typical installation procedure for this piston?
A: Installation requires standard engine rebuilding tools. Ensure the cylinder bore is clean and within service limits. Lubricate the piston pin and connecting rod bushing before assembly. Use a ring compressor to install the piston into the cylinder, taking care not to damage the rings. Torque connecting rod bolts to manufacturer specifications (typically 40-50 Nm for D4BB/4D57).
