water inlet opening.
TYPICAL
1. Inspect impeller and boot
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 meth-
od 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 In-
spection 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.
Clearance should not exceed 1.0 mm (.040 in). If
clearance is greater, disassemble jet pump and in-
spect impeller and wear ring. Renew worn parts.
