ERT_S series Ebbert Rivet Tools (HK1038)
Assembly ERT3S & ERT4S
This procedure is for reassembly of ERT3S & ERT4S.
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 the
surface is free of gouges and nicks that will damage a new
seal. Small nicks and gouges can normally be removed
using a fine crocus cloth.
3. After all seals, O-rings and Back-up rings are replaced,
insert end cap assembly into piston, and insert as a
combination into the tool cylinder.
NOTE: Use caution
when inserting this assembly into cylinder.
Keep
the piston from cocking in the cylinder and nicking the
cylinder wall. This could ultimately cause a seal edge to be
cut. Secure the end cap and support loop assembly with
four screws.
4. Reposition the tool in the vise with the open front of the
cylinder pointing straight up. Use Option “a” or “b” for
filling the tool with hydraulic fluid:
a)
Gravity fill:
Connect the hydraulic line to the power
unit and allow hydraulic fluid to flow from the higher
positioned reservoir into the tool cylinder until it is level
with the front retaining ring, then disconnect the hydraulic
line for installation of remaining components.
b)
Optional fill:
Using the Model 300509 Bleed Pump
Assembly, pump from the hydraulic connector through
the line, filling the tool in the same manner and to the
same level as above.
5.
ERT3S:
Slide the front seal retainer down, using care to
get it positioned straight in the cylinder. The retainer does
not easily slide into the cylinder; it will be drawn into place
later when the handle is secured.
ERT4S:
Making sure the cut-out section will clear the
ears of the retaining ring, slide front seal retainer down,
using care to get it positioned straight in the cylinder. The
retainer does not easily slide into the cylinder; it will be
drawn into place later when the handle is secured.
6. Slide hydraulic seal down over piston threads and wrench
flats carefully to prevent nicking seal edges, and position
in cylinder (ERT3S) or front seal retainer (ERT4S).
Positioning this seal requires some effort to work it in.
Start it down on one side and slowly work it in until the
last small area may be assisted by using the flat side of a
common screwdriver.
7. Install handle and piston rod wiper down over piston and
into contact with front seal (ERT3S) or front seal retainer
(ERT4S). While doing this, hold trigger in position to
allow it to drop behind lock-in pin. Install four screws with
bearing plates with equal pressure to draw handle (and
seal retainer - ERT4S) into position in cylinder. Torque
screws at both ends of the tool to 60–80 in-lbs.
8. Air-bleed tool if necessary and connect to the power
unit for test cycle. The pulling head assembly can now be
installed.
