Impeller/Wear Ring Clearance
This clearance is critical for jet pump performance.
Clearance can be checked from water inlet open-
ing or from venturi side. However, the last method
requires more work.
To check clearance from water inlet side, remove
inlet grate.
To check clearance from venturi side, remove venturi/
nozzle assembly as described in OIL INSPECTION in
this subsection.
Using a feeler gauge with 30 cm (12 in) blades,
measure clearance between impeller blade tip and
wear ring. Measure each blade at its center. Clear-
ance should not exceed 1.0 mm (.040 in). If clear-
ance is greater, disassemble jet pump and inspect
impeller and wear ring. Renew worn parts.
