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 using a soft dolly.
3. Add a small amount of EP 0 grease to the crank pin shoulder and reassemble. Be careful to k
eep
grease off of the crank pin threads. Remember it is left-hand thread. Torque the crank pin to 228
in
ch-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 wit
h
t
he 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 guid
e
t
ube.
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 edge) is facing down toward the anvil. Remember, round to the ground. See Figure 9.
