Description of Change: An improved recoil Spring is now used on certain Excavators. The recoil spring can be rubbed by mud when the mud is compressed around the spring. The mud can rub off the paint and create a pit on the surface that can result in corrosion of the spring. The new Spring is coated with a zinc rich paint. This zinc coating will ionize the steel and help restrict corrosion.

Adaptable To: The new 340-8237 Spring is available as a service replacement of the 239-4350 Spring. If moisture adheres to the place where the paint peels, the zinc ionizes and steel corrosion is restricted. The new Spring will have a longer service life compared to the former Spring.
