Rocker Arm Bolts for Quad Bashan & Shineray 200-250

Stability for the Valve Train! – Rocker Arm Bolts for Quad Bashan & Shineray 200-250

High-strength rocker arm shafts – Precision within the cylinder head

Ensure the exact guidance of your rocker arms! These Rocker Arm Bolts serve as the shafts on which the rocker arms rotate within the cylinder head. Constant exposure to vibrations and high temperatures makes a flawless surface finish crucial for low-friction engine operation. Worn or scored bolts cause inconsistent valve clearance and disturbing mechanical noise. Made from specially hardened steel, these bolts guarantee minimal friction and maximum wear resistance.

  • And many identical 200cc - 250cc Chinese engines (e.g., Loncin, Zongshen)

• Material: Surface-hardened high-grade steel

• Benefit: OEM quality for high dimensional accuracy and a long valve train service life.

Installation & Maintenance Instructions: (For guidance purposes only)

• Visual Compatibility: Before installation, perform a visual check. Compare the length and diameter of the bolts, as well as any notches or threaded holes at the head end, exactly with your old part.

• Lubrication: Generously coat the bolts with fresh engine oil before insertion. Sufficient initial lubrication prevents dry friction during the first start after repair.

• Fitment: The bolts should slide into the cylinder head guides without excessive force. Check the bores in the cylinder head for cleanliness and debris.

• Valve Clearance: After replacing the bolts or rocker arms, the valve clearance must be readjusted, as the new components may have slightly altered the geometry
