Technical Information
The following figure shows the various components involved in a tip seal
replacement procedure. Refer to the figure 26 as you follow the procedure
(Video is available at Agilent.com).
To remove the worn tip seals:
1 Disconnect the pump from electrical power.
2 Remove (4) M5 socket head bolts (item 1).
3 Remove the front cowling and disconnect the electrical connector
and set the cowling aside.
4 Remove (4) M5 bolts (item 4).
5 Remove the outboard housing axially off the frame (item 5).
6 Remove and discard the worn tip seals (item 6) and the main O-ring (item 7).
7 If compressed air is available, blow any remaining seal debris off the scroll
parts. If seal debris is attached to the sides, use a razor or Exacto knife to
scrape the debris off.
To install the new seals and O-rings:
1 Unpack the tip seals.
Two tip seals are provided in the kit; one fits the orbiting scroll and the other fits
the outboard housing scroll.
2 Install the correct tip seal into the groove of the orbiting scroll (item 8) by.
a. Facing the cutting burrs on the edges of the seal upwards, inserting the
tightly curled end into the center of the orbiting scroll, until the seal is well
seated in the groove and the anchor inside the groove protrudes into the
seal's side (see following figure). The seal may need to be pushed firmly
to sit well into the groove.
The seal is correctly installed when it sits in its entirety into the groove,
sticking out just slightly over the top.
