4.4.1 Replacing the Saver Sub
It is not expected that the saver sub would need to be replaced during normal
operations but if damage occurs to a pressure fitting or a leak is found during
pressure testing then this procedure should be followed.
Ensure that the pressure is bled off.
Do not remove the pressure fittings at this time as they can be used to
provide grip to remove the plug.
Remove the two socket head cap screws and lock washers. (If they
appear unusually tight or difficult to move re-check that the pressure
has been removed).
Grip the pressure fitting and pull out the saver sub with a pulling and
rocking motion. If the pressure fitting has been removed already then
two ¼-20 UNC screws (not supplied) can be used to jack out the sub.
Inspect the o-ring for signs of damage and replace if necessary
Inspect the seal bore for signs of damage and report if necessary
If required, remove the pressure fitting
– clean and inspect the pressure
port.
To re-fit the sub, apply grease to the o-ring and seal bore.
Push the sub into the bore by hand as far as possible and drive home
with a soft faced hammer.
Fit the screws and washers and tighten.
