Damper rubbers, set, Delta (silicone): a set of damper rubbers for Delta mopeds. The rubbers in the rear sprocket drum damp jerks when pulling away and protect the transmission.
Replace the part if the sprocket has play, there is knocking on acceleration and engine braking, or the rubber has cracked or flattened. Install the part with clean mating surfaces and, where possible, with new gaskets and fasteners.
