Setup and Preparation
Before using the SOLAS WR007H tool, ensure you have the following:
- Appropriate wrenches or sockets for the impeller nut.
- Penetrating oil (optional, for stubborn impellers).
- Safety gloves and eye protection.
- A clean workspace.
Important: Disconnect the PWC's battery and ensure the engine is off before beginning any maintenance.
Operating Instructions: Impeller Removal
- Access the Driveshaft: Depending on your PWC model, you may need to remove the pump or other components to gain clear access to the impeller and driveshaft.
- Position the Tool: Slide the SOLAS WR007H tool onto the driveshaft. The internal splines of the tool are designed to engage with the splines on the driveshaft, preventing it from rotating.
- Secure the Tool: Ensure the tool is fully seated and gripping the driveshaft firmly. You may need to hold the tool steady with one hand or use a vice if possible, depending on the access.
- Loosen Impeller Nut: With the driveshaft held stationary by the WR007H tool, use the appropriate wrench or socket to loosen the impeller nut. Note that many impeller nuts have reverse (left-hand) threads, meaning you turn clockwise to loosen. Confirm the thread direction for your specific impeller.
- Remove Impeller: Once the nut is loose, carefully slide the impeller off the driveshaft.
Operating Instructions: Impeller Installation
- Prepare Driveshaft: Ensure the driveshaft splines are clean and free of debris.
- Install Impeller: Slide the new or reconditioned impeller onto the driveshaft, aligning the splines.
- Position the Tool: Slide the SOLAS WR007H tool onto the driveshaft, engaging its internal splines with the driveshaft.
- Secure the Tool: Ensure the tool is fully seated and gripping the driveshaft firmly.
- Tighten Impeller Nut: With the driveshaft held stationary by the WR007H tool, thread the impeller nut onto the driveshaft. Remember to turn counter-clockwise for left-hand threads to tighten. Tighten to the manufacturer's specified torque settings.
- Remove Tool: Once the impeller nut is securely tightened, remove the SOLAS WR007H tool from the driveshaft.
Maintenance
To ensure the longevity and proper function of your SOLAS WR007H tool:
- Cleaning: After each use, wipe the tool clean of any grease, oil, or debris.
- Storage: Store the tool in a dry environment to prevent rust. A light coat of oil can be applied to the metal surfaces if storing for extended periods in humid conditions.
- Inspection: Periodically inspect the internal splines for wear or damage. Damaged splines may reduce the tool's effectiveness and could potentially damage the driveshaft.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Tool slips on driveshaft | Incorrect tool size; Driveshaft or tool splines are worn/damaged; Tool not fully seated. | Ensure correct tool for 20mm shaft. Inspect splines on both tool and driveshaft. Ensure tool is fully engaged. |
| Impeller nut won't loosen/tighten | Incorrect thread direction (left-hand vs. right-hand); Nut is seized; Insufficient leverage. | Confirm thread direction (often left-hand for impellers). Apply penetrating oil. Use a longer wrench or breaker bar for more leverage. |
