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 ven-
turi/nozzle assembly.
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. For
GTX 4-TEC clearance should not exceed 0.35 mm
(.014 in). If clearance is greater, disassemble jet
pump and inspect impeller and wear ring. Renew
worn parts.
