All Hammers shipped from the factory now are equipped with a Valve Liner. When the Valve Seat area is worn the Valve Liner can easily and quickly be replaced. This eliminates the old time consuming and expensive re-machining of the Valve Seat. The Liner also allows Valve timing in the field with field tools and less than an hour’s time.
Old style Vulcan Hammers can be machined to fit the new Liner. Contact the factory for instructions.
