ERT_S series Ebbert Rivet Tools (HK1038)
Disassembly ERT1S & ERT2S
This procedure is for the complete disassembly of the
ERT1S & ERT2S tools . For component identification,
see Figure 2.
1. Unscrew two socket head screws (ERT1S) or four
screws (ERT2S) that secure piston rod guide to the
front of the tool, and remove piston rod guide.
2. Loosen hose clamp/sleeve at rear of tool, and pull
it back far enough to allow clearance for removal of
end cap. From rear of tool, remove two socket head
screws (ERT1S) or four screws (ERT2S) and support
loop assembly.
3. Push piston toward rear of cylinder to remove end
cap/guide tube assembly, piston, and piston forward
stop.
4. Remove remaining seal from front of cylinder.
5. The cylinder is now stripped of parts except retaining
ring. For typical tool service, it is not necessary to
remove this retaining ring. If it is removed, when
replacing it, relocate retaining ring ears at bottom of
cylinder, allowing clearance for hydraulic inlet port.
6. ERT1S : Remove retaining ring and all seals from
piston, and piston rod wiper from piston rod guide.
ERT2S : Remove retaining ring, front seal retainer
and all seals from piston, and O-ring, Back-up ring,
seal, and piston rod wiper from piston rod guide.
NOTE: When servicing the tool to this extent, the
piston rod wiper must be replaced.
7. Remove the O-ring from the end cap.
8. Clean disassembled parts in cleaning solution. While
cleaning the piston, ensure that the small hole in the
“V” groove is open.

Assembly ERT1S & ERT2S
This procedure is for the re-assembly of the ERT1S &
ERT2S tools .
1. When replacing seals, make sure they are correctly
positioned as shown on the Tool Schematic. Wipe
all seals with a thin film of seal lubricant before
reassembly.
2. It is important to inspect the cylinder wall to ensure
surface is free of gouges and nicks that will damage
a new seal. Small nicks and gouges can be removed
using a fine crocus cloth.
3. After all seals, O-rings and Back-up rings are
replaced:
ERT1S : With piston forward stop placed on the piston
shaft, insert end cap assembly into piston, then slide
the complete assembly into tool cylinder.
ERT2S : Insert end cap assembly into piston, then
slide the complete assembly into tool cylinder.
NOTE: Use caution when inserting this assembly
into cylinder to keep piston from cocking in
cylinder and nicking cylinder wall. This could
ultimately cause a seal edge to be cut.
Secure end cap and support loop assembly with two
screws (ERT1S) or four screws (ERT2S).
