Important Notes

• Verify compatibility with your specific generator model, manufacturing number, engine configuration, and production revision before ordering.
• Homelite OEM suppliers identify D266002 specifically as “SPRING VALVE.”
• Ryobi factory documentation uses the description “Valve Spring.”
• Factory documentation specifies two D266002 Valve Springs per applicable engine assembly.
• The valve springs are installed within the same cylinder head assembly as the D261702 Intake Valve, D265903 Exhaust Valve, D261807 Intake Valve Returner, and D93513 Valve Oil Seal.
• The D261805 Exhaust Valve Spring Seat is a separate component and should not be confused with the D266002 Valve Spring.
• Inspect the intake and exhaust valves, valve seats, retainers, oil seals, rocker assemblies, push rods, valve lifters, and related cylinder head components when servicing the valve springs.
• Replace weak, cracked, distorted, excessively worn, heat-damaged, or otherwise defective related valve train components as necessary.
• Valve train service may require specific clearance settings, assembly procedures, and specialized tools. Follow the applicable manufacturer service procedures.
• This listing is for one Homelite D266002 Valve Spring only unless otherwise specified. A confirmed engine assembly may require two springs, so verify the quantity needed before ordering.
• Intake valves, exhaust valves, retainers, valve seals, spring seats, rocker assemblies, push rods, and other engine components are sold separately.
• Match part number D266002 with your generator's illustrated parts diagram or OEM documentation before ordering to ensure proper fitment.
