Straighten or replace bent or damaged parts (WP 0056 00).Step 2. Check for clearance between pins on latch bar and upper and lower striker receptacles. Adjust travel latch clearance (WP 0056 00).END OF TESTING10. UPPER COUPLING WILL NOT ENGAGE IN RECEPTACLE BLOCKStep 1. Check for obstructions such as rocks or debris lodged in receptacle blocks. Free and remove debris from area.Step 2. Check gap between inner-to-inner pontons.Close gap using connecting strip and crowbar until inner-to-inner ponton upper couplingscan be engaged.Step 3. Check alignment during bay-to-bay connection. a. Level top surface of adjoining roadways using coupling tool.b. Draw adjoining bays closer together using grip hoist (TM 5-5420-278-10).Step 4. Check for bent or heavily worn lever or receptacle block. a. Replace bent or worn lever or removable receptacle block (WP 0057 00).b. If transverse receptacle block is worn or damaged, notify supervisor.END OF TESTING11. UPPER COUPLING WILL NOT RELEASE FROM RECEPTACLE BLOCKStep 1. Check to see if lower lock-drive pins were inadvertently disengaged before the upper couplings. Use grip hoist and pull bays together until bay-to-bay upper couplings can be released (TM 5-5420-278-10).Step 2. Check for obstructions between inner-to-inner pontons. Remove obstructions and close gap using connecting strip and crowbar until inner-to-innerponton upper couplings can be released (TM 5-5420-278-10).END OF TESTING12. LOWER COUPLING JAMMED AND WILL NOT LINE UPStep 1. Check for obstruction between bays. Remove obstruction from between bays using crowbar.Step 2. Check alignment of top surface of adjoining roadways. a. Level top surface of roadways using coupling tool.b. Draw adjoining bays closer together using grip hoist (TM 5-5420-278-10).c. Extend yokes (ramp bay only) until lower lock drive pins can be engaged (TM 5-5420-278-10).d. If lower lock-drive pins still will not engage, check lower lock-drive for damage (malfunction 7).END OF TESTINGUnit Mechanical Troubleshooting (Contd)MALFUNCTIONTEST OR INSPECTIONCORRECTIVE ACTIONEND OF WORK PACKAGE
