TM 5-3895-374-24-1 6. Lubricate the piston, seals and cylinder bore and install piston and shaft into the cylinder 7. Using the face spanner wrench tighten the cylinder head into the cylinder tube until the outer face of the cylinder head is flush with the end of the cylinder tube. 8. Install the hydraulic cylinder onto the equipment and connect the hoses. 9 Upon installation of the cylinder, completely extend and retract the cylinder under no load several times to allow trapped air to escape through to the reservoir. 3-4-1 3  Bin Heating System Removal and Replacement See figure 3-23. This procedure assumes a complete removal and replacement of the assembly.  A partial disassembly and replacement is possible.  Follow the procedure to the point of removing only those components requiring repair or replacement. A. Disassembly 1. Shut off the breaker for the surge bin heat in the 120/240 volt electrical panel (LP1) For added safety, unplug cable 128 from the control van and coil this cable at the surge bin. 2. The sloped portion of the bin has an electric heating element mounted under the insulation and the sheet metal cover Remove the rivets or screws holding the sheet metal to the frame on the hopper.  Remove the sheet metal on all four sides. Remove the Insulation 3. Use a chalk or soapstone and trace the routing of  the  heating  element.    It  is  held  in  place  by  wire  clips,  loosen these and remove the element. 4. Remove the cover on the junction box that the element connects to and disconnect the element. 5. The  bin  heat  thermostat  for  this  element  is  in  the  adjacent  junction  box.    Remove  the  cover  to  this  box  and disconnect the wires to the thermostat and remove the thermostat. 6. The two gates on the bin each have a thermostat and a heating element mounted on them under the insulation and  the  sheet  metal  cover.    Remove  the  sheet  metal  on  each  of  the  gates  and  remove  the  insulation.    (See Section 3-4-14). 7 Mark the electrical wires and disconnect them from the thermostat and the element. page 3-651
