tip seal, and spring from the GC/MSD interface. (See
“GC/MSD interface tip

properly aligned, the transfer line clamp screw will be difficult to tighten.

8 Open the bus door and remove it by lifting the door vertically off its hinge
pins.

9000 GC/MS Tail click and run bus connection. Also remove the bolt from the
empty bus connection. (See
Figure 14 .)

the clamp and rotating the clamp down.
11 Push the MS tail heater assembly back a few millimeters. A magnet will hold
the heater assembly away from the 9000 GC/MS Tail.
