Inserting tip seals
NOTE:
Tips seals for Fixed Scroll and Orbit Scroll have opposing
seal cut angles (See NOTE and explanatory diagram below).
Insert tip seal so that the lip of tip seal is on the bottom of
seal groove and inner side of involute and the direction of lip
faces the center of involute (curving spiral). See Figure 5. This
is to be done for both FS and OS sets.
Use caution not to tear or distort lip.
1. Insert new HP tip
seal from the center
section for OS or Orbit
Scroll so that there
will be no clearance at
the tip (start) section
(See Figure 5 and 6).
2. Insert so that new LP
tip seal will contact
closely with HP tip
seal inside Scroll
Groove (See Figure 4
on page 4).
Insert approximately half of the LP tip
seal and remove the tip seal to confi rm
that a notch in the tip seal has been created. This will prevent
movement during installation (See Figure 7).
3. Repeat the same procedure for FS or Fixed Scroll tip seal
set, remove both the dust seal and backup tube located
on outermost side FS set.
4. Insert new backup tube in the FS Scroll in the 6 o’ clock
position (See Figure 8).
5. Insert new dust seal on the backup tube.
6. After replacing tip seal set, reassemble Fixed Scroll set
to the Orbit Scroll. Tighten nuts and bolts temporarily
and confi rm if crankshaft rotates smoothly by hand and
tighten them fi rmly. Tightening torques are:
NOTE:
Assemble so that dust seal and tip seal will not drop
between Orbit Scroll set and Fixed Scroll set.
