UPPER PACKING (9)
Disassembly
Disassemble the coupling rod from the air motor
and the piston (3) from the fluid section.
Unscrew the wetting-cup (4) by means of the
wrench provided with the pump.
Unscrew the cylinder (2) and pull the piston (3)
downwards. Pull the upper packing (9) upwards and
remove the seals (10 and 11).
Reassembly
Change the seals (10 & 11) and lubricate
them.
On the support washer (12), install the seals (10 &
11) (comply with orientation and order) as well as
the blocking washer (13) { upper packing (9)}.
You must install a seal (11), then another one
(10) according to the opposite drawing.The first
seal in contact with the material must be the stiffer
one.
Grease the cone shapped tool (the tool is
supplied with the fluid section).
Position the upper packing (9) on the tool (53).
Slide the piston (3) into the flange (1) by inserting it
from bottom to top.
Position the tool equipped with the seals on the
upper part of the piston.
Slide the seals on the piston. The tool prevents from
damaging the seals when assemblying the piston.
Remove the tool.
Position the seals (always set up on the piston) into
the upper flange (1).
Hold the piston to prevent from its sliding downwards.
Tighten by hand the wetting-cup (4) without tightening the upper flange (1).
After reassemblying, fill up the pump with solvent and increase progressively the pressure
to maximum setting up of the seals.
After half an hour, stop the pump and open the exhaust valve to depressurize.
Retighten the wetting-cup (4) by means of the wrench supplied with the pump in order to be
in accordance with the drawing. Comply with assembly dimension.
Before reassemblying the different components :
-
Clean the parts with the appropriate cleaning solvent.
-
Install the new seals if it is necessary after having lubricated them with PTFE grease.
-
Lubricate the piston and the inside of the cylinder to prevent from damaging the seals.
Install new parts if it is necessary.
