FAQ

Q1: Is this a complete piston assembly, and does it include rings and pins?
A1: This part is typically sold as a complete piston assembly, which includes the piston body, wrist pin, and circlips. Piston rings are usually sold separately (Ring Set). Please confirm the exact contents with your sales representative at the time of order.

Q2: Can this piston be used for both the 4HK1 and 6HK1 engines without modification?
A2: Yes. The part numbers 8981529011 and 8980235261 are validated for use in both the 4-cylinder (4HK1) and 6-cylinder (6HK1) engine variants where specified. Always verify your engine’s specific model and serial number before purchase.

Q3: What is the recommended procedure when installing a new piston in these engines?
A3: We strongly advise following the OEM service manual. Critical steps include: measuring cylinder bore wear, checking piston-to-cylinder clearance, ensuring proper ring end-gap, and using new connecting rod bolts torqued to specification. Always replace components in sets (e.g., all pistons in an engine bank) for balanced performance.
