Reassembling the hammer
After thoroughly cleaning and drying the components and checking for excessive wear,
reassembly can occur.
1. Apply a coating of the supplied EP 1 grease around the Piston O ring (BS222) and
outside of the piston, and gently push back into the housing using a soft dolly.
2. Add a small amount of grease to the Crank Pin (CEPD 38 PIN) and reassemble
remembering it is
Left Hand thread . Do not over tighten this pin; maximum 30Nm.
3. Add a coating of EP 1 Grease to the outside of top hammer, and gently push into the
housing. The O ring will be at the top.
4. For the bottom hammer section, slide the Damper Washer (CEPD DAMPER 3MM)
back onto the Hammer Housing (CEPD936-1). Then add a light coating of EP1 Grease
to the 3
rd
Hammer (CEPD 937) and push through the flanged adapter (CEPD938-1).
Push this into the Hammer Housing (CEPD936-1).
5. Align the two flat faces of the 3
rd
Hammer (CEPD937-1) with the two holes in the
Hammer Housing (CEPD936) for the retaining dowel pins and gently tap the dowels
(CEPDPIN 8X36) into place.
Note the dowels can only be driven from one direction.
6. Reassemble the damper components with a small amount of EP 1 Grease to all
components. (CEPD 22/ 20 & 2xBS326).
For the damper assembly:
• Place the hammer housing (CEPD936) on a bench and
place one of the damper O rings (BS326) in the cup.
• Place the hammer guide (CEPD 20) inside the cup on
top of the first O ring with internal radius facing down.
Once assembled the Flat side needs to be to the top of
machine. The curved side to bottom of the machine.
This is important – if assembled incorrectly this could
cause damage to the hammer.
• Place the second Damper O ring (BS326) on top of the hammer guide, inside the
cup.
• Place the damper washer (CEPD 22) on top of the O
ring, ensuring the small diameter spigot is facing up. This
spigot aligns inside the cylinder liner.
• Fit the damper assembly in the bottom guide tube over
the bottom hammer.
7. Install the bottom guide section back into the main housing and insert handlebars
and springs back into the bottom housing in this process, ensuring the thin section O
ring is not damaged between the housings.
8. Apply medium strength thread locking compound to the 4 socket screws (M8x80) in
the flanged adapter (CEPD938-1) and tighten to 20Nm.
9. Apply medium strength thread locking compound to the 8 guide tube retaining bolts
(M8X18) and ensure lock washers are fitted to the screws. Put all screws finger tight
into the respective holes and then tighten in an alternate pattern.
10. Apply 75ml of the supplied grease to the crank area, and reinstall the 4 socket screws
(M4x10) using medium strength thread locking compound.
All screws must be correctly tightened in an alternate pattern, as machine
damage can occur from loose or lost bolts.
