Figure 4. 25271--903 Seal Assembly
This seal is not designed for operation at
temperatures above 160_F (71_C). Do not
use at higher operating temperatures.
If the balance ring (9) was removed, the replace-
ment ring should be pressed into the intermediate
before installing the seal. Position the ring in the in-
termediate bore with the chamfered end toward to-
ward the bore shoulder and press it into the bore
until fully seated.
NOTE
The balance ring must be fully seated in the inter-
mediate bore, otherwise binding and/or excessive
wear could result.
If the intermediate was removed, lay it on a flat sur-
face with the impeller side facing up.
Lubricate the stationary seat O-ring with light oil
and install it in the stationary seat. Use thumb pres-
sure to press this subassembly into the intermedi-
ate bore until fully seated. Be careful not to damage
the seal face. After installation, wipe the seal face in
a concentric pattern with a clean, lint-free cloth to
remove any fingerprints.
Secure the intermediate to the engine with the
hardware (26 and 27).
Be careful not to damage
the stationary seat on the shaft threads.
Slide the rotating portion of the seal (consisting of
the retainer, bellows and rotating element) onto the
sleeve (8) until the rotating face is
just flush with
the chamfered end of the sleeve. Slide the sleeve
onto the shaft until the seal faces contact. Continue
to push the sleeve through the seal until it seats
against the shaft shoulder.
Install the seal spring. Make sure that all compo-
nents of the seal are seated squarely.
