Setup
Before using the impeller wrench, ensure you have the correct size wrench for your specific impeller nut. The WR007 is designed for standard SOLAS impeller nuts. Always work in a well-lit area and ensure the personal watercraft or jet boat is securely supported and powered off.
Required Tools (Not Included):
- Appropriate torque wrench (for installation)
- Impeller removal tool (if impeller is seized)
- Marine grease or anti-seize compound
- Safety glasses and gloves
Operating Instructions
Impeller Removal:
- Ensure the watercraft is stable and the engine is off.
- Locate the impeller and the impeller nut at the rear of the jet pump.
- Carefully align the four prongs of the SOLAS WR007 Impeller Wrench with the corresponding slots on the impeller nut.
- Apply firm, steady pressure and turn the wrench counter-clockwise to loosen the impeller nut. If the nut is seized, use penetrating oil and allow it to soak.
- Once loosened, remove the impeller nut and then the impeller.
Impeller Installation:
- Clean the impeller shaft and apply a thin layer of marine grease or anti-seize compound to the threads.
- Carefully thread the impeller onto the shaft by hand until it is snug.
- Place the SOLAS WR007 Impeller Wrench onto the impeller nut, ensuring proper engagement of the prongs.
- Using a torque wrench (if specified by the watercraft manufacturer), tighten the impeller nut clockwise to the recommended torque specifications. Do not overtighten.
- Verify that the impeller spins freely without obstruction.
Maintenance
The SOLAS WR007 Impeller Wrench requires minimal maintenance. After each use:
- Clean the wrench with a damp cloth to remove any dirt, grease, or marine residue.
- Dry the wrench thoroughly to prevent corrosion.
- Store the wrench in a dry place, away from direct sunlight and extreme temperatures.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Wrench slips on impeller nut | Incorrect wrench size; Worn impeller nut; Improper engagement | Ensure WR007 is the correct size for your impeller nut. Verify prongs are fully seated in slots. Inspect impeller nut for wear. |
| Impeller nut is seized | Corrosion; Overtightening | Apply penetrating oil and allow to soak. Use an impact wrench with caution if necessary, or consult a professional. |
