The most common failure of the Star Titan scaler is the rotor, and this is a repair that you can perform internally, without any special tools or equipment.
If the rotor fails, the Star Titan Scaler emits a low pitched “bubbling” sound and power is drastically reduced. To replace the rotor:
Climber disassembly
- Remove the tip of the Star Titan scaler.
- Then remove the scraper from the air supply.
- Remove the nose. The force of the hand should be sufficient to remove the nose, turn it counterclockwise, unscrew the nose and remove it by hand. Put the nose in the ultrasonic cleaner
- The metal tube that is now exposed is the shaft. Using your fingers, remove the 2 large shaft O-rings from the front of the scraper shaft and discard. (All o-rings must be replaced).
- Remove the main casing. The main casing is the part closest to the exposed shaft. The force of your hand should be sufficient to remove the main casing. Also place the main housing on the ultrasonic.
- Looking towards the base of the main shaft, you will now see the rotor surrounded by four rings. (There are two main variations of the shaft rotor area. One has 4 quad rings and the other has 2 quad rings. Make a note of your configuration.
- Slide the upper quad rings up (toward the front of the axle) and out.
- Slide the rotor to turn it off.
- Remove the remaining quad rings. Discard the quad rings and rotor. These are mandatory replacement parts.
- Wipe the shaft down with a 2×2 prep pad.
Reassembly of the climber
- Open your rebuild kit. Depending on your configuration, place 1 or 2 quad rings on the shaft and slide them into the quad ring slots at the base of the shaft.
- Slide the new rotor onto the shaft
- Slide the remaining quad rings (also placed in the quad ring grooves).
- Remove the parts from the ultrasonic cleaner; Rinse them well and dry them well. Use the air in your syringe to dry the inside of the components.
- Put a drop of oil on the threads to make installation easier, and then screw the main casing back onto the base until hand tight.
- Place the 2 front axle o-rings over the exposed axle and slide it until they rest against the main casing.
- Install Nose. Slide the tip over the exposed mainshaft and then screw the tip clockwise until hand tight.
Your Star Titan Scaler is now ready to go back to work for you. If the power is inadequate after replacing the rotor, disassemble again, slide the rotor out and invert.
