Type 57 Gear Operated Parts List (Gear: Sizes -/" ") Troubleshooting What if fluid still flows when the valve is closed?. Make sure lever or gear is in a fully closed position (gear type may require travel stop adjustment].. Liner is damaged or worn. Replace liner.. Disc is damaged or abraded. Change disc. 4. Foreign material is caught between seat and disc. Remove the substance. 5. Mating flange bolts either over-tightened or unevenly tightened. Retighten properly. What if fluid leaks outside between seat and mating flange? Caution. Seat damage. Change seat.. Mating flange bolts not tightened with proper torque or unevenly tightened. Retighten to the appropriate torque. What if valve does not operate smoothly?. Foreign material is caught between disc and seat. Remove the material and clean.. Lever or gearbox is damaged. Replace..
