Rotor Maintenance 1. Remove the cap on the rotor valve and apply a little rotor spindle oil to the rotor bearings. * After applying the oil, remove the excess oil. After applying oil, replace the cap and move the lever a few times to distribute the oil evenly. 26 Maintenance 2. Apply a little rotor spindle oil to the rotor spindle and receiver. 3. Apply a little lever oil to each linkage of the lever assembly. * Remove excess oil and use a gauze cloth to clean the smaller parts. ¦ Once or Twice a Month Maintenance . Valve Slide Maintenance 1. Depress the valve levers and remove the valve slides. 2. Wrap a cleaning rod with a gauze cloth leaving no bare metal exposed, and remove dirt from the valve slides and the insides of the outer pipes. 3. Use the gauze to remove dirt from the surface of the valve slide, then apply a little slide grease. 4. Slide the valve slide in and out a few times to distribute the grease evenly. Then wipe off any extra grease that comes off the slide. 27 Maintenance ¦ Twice Yearly Maintenance . Cleaning the Instrument 1. Prepare a brass soap water solution using between 10 to 15 parts warm water (78°F to 88°F) and 1 part brass soap. Before putting the instrument into the solution, remove the valve slides. 2. Apply some soap water solution to the brush on the end of flexible cleaner and use the cleaner to clean the inside of the instrument’s tubing. 3. After cleaning the instrument, use clean water to thoroughly rinse out the dirt and soap. 4. After completely removing all moisture with a gauze, apply oil and grease. Take Care When Cleaning Inside of the Instrument Never dismantle the rotors. Also, when rinsing the tubing with water, run water through the main tuning slides in the opposite direction of the airflow. If water is run through the instrument from the mouthpiece, dirt can become clogged in the valves causing the valves to become sluggish. 5. Apply some soap water solution to a mouthpiece brush and insert it into the throat to clean the mouthpiece, then thoroughly rinse it out with clean water. 28 Tying the Rotor Strings . Wind the string as shown in the illustration below, and tighten the string stopper screw. Wind the string around the screw in the same direction that the screw tightens. After winding, use the String Stopper Screw B to adjust the lever’s height. Rotor Stem Screw String Stopper Screw B String Stopper Screw A Lever Linkage Lowers the lever Raises the lever The YHR-567/567D is used in this illustration. ¦ Switching the 4th Lever Function . F/Bb Double Horn The Yamaha double horn is designed so that it normally plays in the key of F (open F) when the 4th lever is not depressed, and in the key of Bb when the 4th lever is depressed. However, by re-configuring the linkage as shown in the illustration below, this function can be reversed so that the horn plays in Bb (open Bb) when the lever is not depressed, and in the key of F when the lever is depressed. To use this setup, move the string and the str...
