Product information "Piston Pin for Quad Bashan & Shineray 200-250cc"
The Solid Link in the Engine's Core! – Piston Pin for Quad Bashan & Shineray 200-250cc
High-precision wrist pin – The load-bearing connection between piston and connecting rod
Ensure your engine's smooth operation! The Piston Pin (Wrist Pin) is a highly stressed component that transfers the combustion force from the piston to the connecting rod. It must withstand extreme pressure and rapid directional changes. A worn or damaged pin leads to dangerous engine knocking and can, in the worst case, cause catastrophic engine failure. This replacement pin is made of specially hardened steel and features a perfectly ground surface for minimal friction within the piston and rod bearings.
Visual Compatibility: Before installation, perform a visual check. It is essential to measure the outer diameter and the total length of the pin with a caliper and compare the values with your old part.
Fitment: The pin should fit into the piston with a smooth, "sliding" feel. Never use force or a hammer, as this could deform the piston. Lightly heating the piston can make installation easier.
Lubrication: Generously coat the pin with fresh engine oil or assembly lube before insertion to ensure lubrication during the critical initial start-up phase.
Securing: Always use new circlips (G-clips) during installation. Ensure they snap fully and audibly into the grooves in the piston. The opening of the clip should point up or down (not to the side)
