Section 6: Troubleshooting Guide General Troubleshooting Guide Control Head Troubleshooting Problem Head doesn’t release dump valve Head releases dump valve prematurely Tripline jams on returning Tripline doesn’t return Possible Cause Solenoid malfunction Jammed linkage Loose trip block bolts Links are above center Worn catch at point Tripline sleeves are fouling cast lugs on head. Broken spring in reel Solution Check the electrical connections for proper operation of the solenoid. A click should be heard when the circuit is closed. See picture 1 on the following pages. Check the white wires on the solenoid for shorting. Check terminal block for loose wires. Check for a burned-out solenoid, measured with an ohmmeter, the solenoid should have about 5.7 ohms resistance. A higher resistance may indicate a poor connection or a burned out solenoid. A lower resistance may indicate a shorted-out solenoid coil. With the cover plate removed, activate the solenoid and check for jamming of linkage. Check terminal block for loose wires. See picture 1 on the following pages. The tail of the catch may ride up on the bearing. Activate solenoid to release. See picture 3 on following pages. Check that the spring link is resting on the body of the stop bolt and not on the head of the bolt, with the control head sitting vertically. See picture 2 on the following pages. Check the catch for burrs at the bearing or the point. The point can be worn by the passage of the trip line bullet. Remove burrs with a fine file. See pictures 4 and 7 on the following pages. Check for rifling in the trip block and deformation on the top of the bullet. Tighten trip block bolts. See picture 5 on the following pages. Check that links are below center line of clevis pins. Adjust links. See picture 6 on the following pages. Check the catch point for wear at the bullet. Replace catch. See picture 7 on the following pages. Pull the tripline completely out. Check that the swaged sleeves at the end of the tripline are not fouling the cast guide lugs on the head and cover. Round the end of the swage sleeves with a file. If necessary the lower set of cast lugs (closest to the trip block) on the head act as a safety keeper to prevent a tripline broken at the top end from causing a tail rotor strike. The swage blocks should not pass between them. See picture 8 on the following pages. Check for a broken spring in the reel. A broken spring is indicated if the tension on the reel doesn’t increase as the reel is wound, or if the tension increases in jerks or the spring seems to “slip” inside the reel. See Spring Power Reel Replacement for reel replacement procedure. We Engineer Solutions Bambi Bucket Service Manual – Models 5566-HL9800 (Version D) 24
