Start with the application branch
Measure outside diameter, clutch-face diameter, crank bolt circle, step height, ring-gear tooth count and any timing or trigger features. State whether bolts and pilot bearing are included.
Resurfacing history and heat checking affect serviceability but cannot establish application. Do not infer a dual-mass design or conversion suitability without documented evidence.
Identification checkpoints before price comparison
For flywheels, record engine and 6mt code, verify overall and clutch-face diameter, and photograph crank bolt circle and step height on both the installed and removed component.
Scoped OE reference
Research did not reconcile a stable Civic reference across engine and 6mt code, overall and clutch-face diameter and crank bolt circle and step height; an old label, casting or vehicle-specific catalogue result is still required. Use a clear record of crank bolt circle and step height to continue the review without assigning a guessed number.
Common order boundaries
Build a comparable B2B order line
Provide engine/transmission codes, old flywheel measurements, ring-gear tooth count, clutch-kit pairing and whether conversion parts are explicitly requested.
Quote original-style flywheel separately from single-mass replacement flywheel, documenting trial and repeat quantity, destination, Incoterm, label requirements and included hardware for that SKU.
Export packing checkpoint
Apply corrosion protection to the machined face, cover ring-gear teeth, immobilize bolts and use a weight-rated carton with dense edge support.
Common buyer questions
How does engine and 6mt code change the Civic flywheel order?
Measure outside diameter, clutch-face diameter, crank bolt circle, step height, ring-gear tooth count and any timing or trigger features. State whether bolts and pilot bearing are included. Record engine and 6mt code, overall and clutch-face diameter and the installed part evidence before treating candidates as comparable.
Which views document crank bolt circle and step height for Flywheels?
Photograph the installed location, the complete removed flywheel, crank bolt circle and step height, every connector or fluid interface and the mounting points. Add a ruler view with named endpoints where dimensions are relevant.
Why is no starting number shown for Flywheels?
Research did not reconcile a stable Civic reference across engine and 6mt code, overall and clutch-face diameter and crank bolt circle and step height; an old label, casting or vehicle-specific catalogue result is still required. For flywheels, use the old reference, label, casting and vehicle record rather than borrowing a number from a visually similar Civic branch.
How should original-style flywheel be separated for trade packing?
Provide engine/transmission codes, old flywheel measurements, ring-gear tooth count, clutch-kit pairing and whether conversion parts are explicitly requested. Apply this packing control: Apply corrosion protection to the machined face, cover ring-gear teeth, immobilize bolts and use a weight-rated carton with dense edge support. Quote original-style flywheel as its own SKU with trial and repeat quantity, destination and buyer-label requirements.
