FAQ
Q1: How do I confirm if my engine needs a +0.50mm oversize piston?
A: You must measure the cylinder bore after honing. If the bore diameter exceeds the standard service limit (typically 72.00mm for D722), the +0.50mm piston (matched with a 72.50mm bore) is required. Always consult your engine service manual.
Q2: Does this piston come with rings and a pin?
A: This listing is for the piston only. For a complete rebuild, we recommend purchasing a matching piston ring set and wrist pin separately to ensure proper gap clearance.
Q3: What is the installation procedure for this oversize piston?
A: Installation requires professional machining. The cylinder must be bored and honed to 72.50mm with proper cross-hatch pattern. Ensure the piston ring gaps are staggered 120 degrees apart and lubricate the cylinder wall with engine oil before assembly. Torque connecting rod bolts to OEM specifications (typically 18-20 ft-lbs).
