10. Remove four 1/4" hex bolts and stationary seat retainer ring.
(See Figure 28, items A and B).
11. Pull the stationary seal and L-
gasket out of the backplate.
(See Figure 28, items C and D).
NOTE: The stationa
ry seal is brittle. Prying or hammering on the
seal plate can shatter the seal. If the stationary seal cannot be
removed by hand, place a 2-1/4 inch diameter plastic or wood rod
on the impeller side of the seal and apply even pressure to dis-
lodge the seal.
Inspect Parts
Once disassembly is complete, perform the following inspections.
1. Examine all seal surfaces and replace seals that have
become scratched, cracked and/or braised.
2. Inspect all o-rings and o-ring seats for abrasions, cuts or
oth
er wear that could cause leakage.
3. Clean all seat areas and alignment surfaces.
NOTE: Stationary seals are reversible. Use both sides before
replacing.
NOTE: Replace the rotary seal when the seal face extends less
than 1/32 inch (1mm) from the body See Figure 29.
