3) Remove the inlet side plate (Refer Removal/
Replacement Inlet Connection Side Plate).
4) Remove circlip (5) from end of swivel shaft
assembly (1) and slide the inlet shaft from the swivel
body (4).
5) Carefully remove the existing O-Rings by lifting O-Rings
out from grooves using a small screwdriver. With
o-rings extended, cut through the O-Ring onto the
screwdriver face. Be careful you do not score o-ring
grooves.
Do not damage or score inlet shaft surface when
removing or cutting o-ring.
CAUTION
5) Before fitting the new o-rings ensure that both the inlet
shaft and swivel are thoroughly wiped clean. Apply
‘Tranz’ 1434 lubricant (supplied in kit) or equivalent to
the o’ring grooves of the inlet shaft.
6) Slide the o-ring applicator sleeve (supplied in kit) over
the inlet shaft to expose only the furthermost o-ring
groove. Put the first o-ring onto the sleeve and slide up
to the exposed groove. Withdraw the sleeve, stopping
at each groove, and fit the o’rings one at a time
following the same procedure.
SWIVEL RE-ASSEMBLY
7) Slide the inlet shaft back into the swivel body and
replace the circlip. Note that if the circlip groove is not
exposed after fitting, the swivel body is back to front.
GAS LEAK TEST PROCEDURE
Test Oxygen /Acetylene hose lines seperately. Ensure
that all connections from the cylinder through to the torch
are tight.
1) Close both torch valves.
2) Open the Oxygen cylinder valve and adjust the delivery
pressure to 25psi or more.
3) Close the Oxygen valve and observe the delivery
pressure gauge. If a drop in pressure occurs,
re-pressure the hose and test all the connections
including the hose, swivel and swivel body by
brushing with warm soapy water solution looking for
the presence of any bubbles.
4) Open the Oxygen valve at the torch and re-close to vent
the Oxygen line. Repeat steps 1, 2 and 3 with the
Acetylene, with the delivery pressure set at 10 psi. Vent
the Acetylene line.
5) Replace or repair any faulty items immediately and
repeat ‘Leak test’ procedure.
