Good To Know

Q: Can a rotary valve be reused after removal? A: A rotary valve should not be reused once removed because the sealing surface and timing can be affected, so a new valve is recommended.

Q: Does this valve require special tools to install? A: Installation requires a degree wheel or timing tool to set the correct opening angle, along with a replacement cover gasket.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
