Figure 3. 25271−192 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 intermediate was removed, lay it on a flat sur-
face with the impeller side facing up. Subassemble
the O-ring in the stationary seat and press it into the
intermediate bore until it seats squarely against the
shoulder. Install the seal ring (7) on the shaft and
secure the intermediate to the engine with the
hardware (19 and 20, Figure 1). Be careful not to
damage the stationary seat on the shaft threads.
NOTE
If the intermediate was not removed, subassemble
the O-ring in the stationary seat and use thumb
pressure to press it into the intermediate bore until it
seats squarely against the shoulder.
Subassemble the rotating element in the retainer
and bellows, then slide this subassembly onto the
shaft sleeve (5) until the face of the rotating element
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 seal ring (7).
Position the seal spring on the retainer and pro-
ceed with Pump Reassembly.
Pump Reassembly
(Figure 2)
If the wear ring (12) was removed, press the re-
placement ring into the casing bore until fully
seated against the casing shoulder.
NOTE
The wear ring must seat squarely in the casing bore
or binding and/or excessive wear will result.
Inspect the impeller and replace it if cracked or
badly eroded. Install the same thickness of impel-
ler shims (4) as previously removed and screw the
impeller onto the shaft until tight.
