Reassembly
After thoroughly cleaning and drying the hammer components and the cylinder, reassembly can be
done.
1. Wear eye protection.
2. Apply a wipe of EP 0 grease around the O-ring and outside of the piston, and gently push it
back into the housing. Be careful not to score any metal parts.
3. Add a small amount of EP 0 grease to the crank pin shoulder and reassemble. Be careful
to keep grease off the crank pin threads. Remember it is left-hand thread. Torque the crank
pin to 228 inch-pounds.
DO NOT OVERTIGHTEN THIS PIN.
4. Add a wipe of EP 0 grease to the outside of the hammer and gently push it into the housing
with the O-ring toward the top.
5. For the anvil section, add a wipe of EP 0 grease to the anvil, and push the anvil into the
guide tube.
6. Reassemble the damper assembly, adding a small amount of EP 0 grease to all
components. The hammer guide ring should be oriented correctly so the side with the large
chamfer (slightly rounded/sloped
edge) is facing down toward the anvil. Remember, “
round
to the ground”
. See Figure 9.
7. Install the metal damper washer back over the anvil.
8. Install the bottom guide section back into the main housing. Be sure to install the new
bottom housing O-ring.
9. Insert the anti-vibration springs back into the handlebars and reinstall them into the upper
and lower handle cups. When parts are inserted correctly, there will be resistance from the
springs to seat the lower driver body. This is normal.
10. Reinstall the bottom housing bolts with new Loctite. You must clean the bolt and the area
of the bolt hole with parts cleaner to remove any grease residue. The Loctite will not be
effective if grease is present. Torque these bolts to 132 inch-pounds.
