SPRING - VALVE OUTER (Doosan DWYT9012948-33)

A worn valve outer spring can cause incomplete valve closure, leading to reduced compression and potential misfiring. This aftermarket replacement part references Doosan catalog number DWYT9012948-33. The spring provides the mechanical force needed to return the valve to its seated position after each cycle. Over time, fatigue or breakage of this spring may result in valve float, which can damage the valve seat or piston. In a typical four-stroke cycle, the spring must withstand repeated compression and extension without permanent set. Verify the serial number or application, then call (562) 693-7748.
