When it comes to unclogging a spindle motor, it's important to handle the task with care to avoid causing further damage. Here are some leading methods you can try:
1. Power off and inspect: Start by turning off the device and disconnecting the power supply. Inspect the motor for any visible debris, foreign objects, or kinks in the water lines that may be causing the clog. Use a flashlight to get a clear view.
2. Soft brush or toothbrush: Gently brush the motor's exterior and the area around the spindle with a soft brush or toothbrush. This can help dislodge any loose dirt or debris that may be causing the clog. Avoid using excessive force or harsh bristles that could scratch or damage the motor.
3. Compressed air: Remove the two water lines from the spindle motor, then remove the spindle motor from the clamp. Having a small bucket or pan will help keep water splashing on your machine to a minimum.
Using a can of compressed air or an air compressor with a nozzle attachment, alternate blowing compressed air into both water fittings on the spindle motor. This can effectively dislodge loose particles that may be causing a clog.
4. Cleaning solvent: If there is stubborn residue or dirt that cannot be removed with air or brushing alone, you may consider using a mild cleaning solvent. An example is a 1:1 solution of white vinegar and distilled water. Be sure to follow the instructions on the solvent you choose and flush with clean distilled water afterward.
Spindle with submersible pump and bucket:
Empty then fill the bucket with a 1:1 white vinegar and distilled water solution so that the pump is completely submerged by at least 1 inch (approx 2-3 gallons in total). Turn the pump on by plugging the power cord into an outlet or power strip. Let the pump push the vinegar and water solution through the water lines and spindle motor for 30 minutes to an hour.
Next, rinse the bucket out and fill it with 2-4 gallons of fresh water and place the outlet water line into a separate bucket. Turn the pump on and let the fresh water flush out the vinegar and water solution into the second bucket. This should take approximately 2-4 gallons. While flushing out the water lines, you should see the water flowing or an increase in flow on the flow meter. If not, repeat using compressed air, then the water/vinegar solution for 30 minutes to an hour.
Once the water lines are flushed out, rinse the bucket and pump once again, then fill will 3-4 gallons of distilled water or other Recommended Coolants for Spindles.
Spindle with eCool system
Unplug the power supply and remove the black outer cover of the eCool pump by loosening the four Phillips head screws on the sides. To drain the reservoir, carefully remove the inlet line from the spindle motor and place the line in a cup or bucket. Next, power on the eCool pump until the reservoir is empty, then unplug the power supply to turn off the pump.
Reconnect the inlet line to the spindle motor and fill the reservoir with a 1:1 white vinegar and distilled water solution, then turn the pump back on. You may need to fill the reservoir again after the water lines have filled up. Let the pump push the vinegar and water solution through the water lines and spindle motor for 30 minutes to an hour.
Next, drain the reservoir by disconnecting the inlet line from the spindle motor and running the eCool pump. Reconnect the inlet line to the spindle motor then disconnect the Outlet water line from the eCool. The outlet water line is the top hose fitting on the heat exchange. The outlet line is released by pressing and holding in the circular fitting, then pulling the water line out. Place the loose oulet line into a small bucket, then fill the reservoir with fresh water. Turn the pump on and continuously fill the reservoir with fresh water (about 1-2 gallons total) to rinse the pump, spindle motor, and water lines. While flushing out the water lines, you should see the water flowing or an increase in flow on the flow meter. If not, repeat using compressed air, then the water/vinegar solution for 30 minutes to an hour.
Once the water lines are flushed out, reconnect the outlet water line by pressing and holding in the circular fitting and pushing the hose into it. Once seated, pull out the circular fitting to secure the hose. Lastly, fill the reservoir with distilled water or other Recommended Coolants for Spindles, then secure the black cover back into place.
