This product is a CFMoto OEM-spec dowel pin (roller pin), part number 30410-00800, size P8x11.8 (8mm diameter × 11.8mm length). Dowel pins are critical alignment components used during engine assembly, installed at the mating surfaces between crankcase halves, cylinder block, cylinder head, and other components. They ensure precise alignment between parts, prevent relative movement, and guarantee assembly accuracy and sealing effectiveness.
Dowel pins are easily lost, damaged, or deformed during engine disassembly and reassembly. Timely replacement of missing or damaged dowel pins is essential to maintain engine assembly precision and prevent oil or compression leaks.
✅ Genuine Quality Assurance: Manufactured strictly to CFMoto original technical standards. Dimensional accuracy and material hardness are identical to the original part for perfect fitment.
