Servicing of Hammer and Anvil (Rebuild)
Bottom Driver Body
• Wear eye protection.
• Remove the 6 bolts on the bottom half of the lower driver body. Be aware that the handle tubes
have anti-vibration springs that are installed under tension. The damper assembly washer will
sometimes be removed with the lower driver body, or it may remain in place in the upper driver
body.
• Remove the damper section and inspect the rubber O-rings and steel components for wear or
debris. Take notice of the orientation of the damper assembly parts, as they must be oriented
the same way when reinstalled.
• Remove the anvil (hammer that hits the post). Locate the Viton O-ring and replace it at this
time.
The anvil is made of high-quality, hardened-tool steel and should not show any signs of wear.
Thoroughly clean the anvil. See Figures 5 and 6.
