TM 5-3895-374-24-2 12. Remove the clevis pin holding the air cylinder shaft clevis to the plug valve lever.  Lower the air cylinder so that it does not interfere with the disassembly. 13. Remove the three way plug valve by splitting it at the two flanges.  Remove the four bolts holding it to the asphalt return line.  Remove the four bolts attaching it to the asphalt meter.  Remove the valve. 14. Remove the four bolts in the flange between the asphalt pump and the asphalt meter.  Remove the asphalt meter by removing the four fasteners in the base of the meter.  The assembly can be lifted clear of the base. B. Inspection 1. Clean all components thoroughly.  Clean them in a bio-degradable solution intended for the removal of liquid asphalt products. 2. Replace all flange gaskets with new ones. 3. The   asphalt   meter   should   be   inspected,   tested   and   disassembled   according   to   the   manufacturer’s instructions in Section 3-7-8. 4. The three way plug valve should be inspected for wear.  Remove the valve core and inspect the plug and openings.    If  this  portion  is  worn  or  damaged  it  should  be  replaced.    It  may  allow  asphalt  past  the  core slitting the flow rather than directing it to the correct location. 5. Inspect  all  heat  transfer  lines  for  damage  to  the  line  or  the  threaded  ends.    Replace  any  lines  that  are damaged or suspicious. C. Assembly NOTE Assembly during an overhaul would only proceed after the disassembly and inspection have been completed in Sections 3-7-5 and 3-7-10. 1. Clean the rear deck of asphalt and debris prior to beginning the assembly. 2. Install the asphalt meter to the deck.  Install the four bolts, washers and nuts that hold it in place.  Install the gasket  between  the  flanges  of  the  asphalt  meter  and  the  asphalt  metering  pump.    Install  the  four  flange bolts and tighten.  Tighten the bolts holding the meter to the deck.
