2 Grip the Bal seal between your thumb and index finger and pull it off.
Figure 8-3 Removing Bal seal
3 Install the new Bal seal spring-side up, just above the threads for the SIP
retainer.
4 Reinstall the retainer and outer sleeve.
Tighten the retainer enough to hold it in place, and slide the outer sleeve
over the SIT, into the retainer opening. Push the sleeve up as far as it goes as
you continue tightening the retainer.
5 Gently push the seal in place to seat it.
If the seal does not remain in position when you let go, hold it with one hand
while you reinstall the retainer. The seal seats as you screw on the retainer.
6 Install a sample tube on the SIP.
If the sleeve hits the bottom of the tube, loosen the retainer slightly, and
push the sleeve up. Retighten the retainer.
