Tighten adapter fasteners evenly to avoid cocking or damaging adapter.
13. Replace impeller and shims, ensuring that key (Ref. No. 8) is in place and
lock impeller to shaft with fastener and impeller seal on fastener.
14. Replace volute seal and volute with fasteners, ensure that check valve
(Ref. No. 12) is in place then remount casing seal and pump casing with
fasteners and nuts.
IMPORTANT: Always inspect all seals when unit is disassembled. Replace
when rubber is hard, cracked, or worn.
When reassembling parts with O-ring seals or gaskets, it is sometimes helpful
to apply a small amount of soapy water on O-ring so that parts slide over O-ring
without pinching or shaving it.
SHIM ADJUSTMENT
When installing a replacement impeller or mechanical seal, it may be necessary
to vary the number of shims (Ref. No. 21) that will be required. This is easily
done by adding one 0.010” shim more than was removed and reassembling
pump as described.
Ensure that casing is snugly in place and check shaft to make sure it is turning
freely. If it turns freely, check to ensure that adapter (Ref. No. 3) and casing
(Ref. No. 15) are fitted tight together. If they are not, tighten fasteners (Ref.
No. 16) and recheck shaft for free turning. Tighten carefully, turning shaft while
tightening. If shaft seizes before fasteners (Ref. No. 16) are completely tight,
disassemble pump and remove one shim and repeat reassembly.
If any time during above operation shaft does not turn free, follow procedure
indicated above and repeat procedure.
Above procedure ensures that pump will have proper running clearance (less
than 0.010”) between impeller and casing and perform like a new unit with new
impeller or motor.
