SERVICE MANUAL 15. Insert a 12.7 mm (i") diameter rod or equivalent through the exhaust port in the bottom cap (Item 29  of  Fig.  23)  and  into  the  cross  hole  of  sleeve (5) to maintain alignment. If  the  cross  holes  are not aligned, the unit will not operate. 16. Apply   a   non-hardening   sealing   compound    to thread of the unloader valve nut (Item 27 of Fig. 23) and install the nut. Tighten nut to 81 Nm (60 ft.  lbs.)  maintaining  the  alignment  of  the  cross holes    of    sleeve    (5).    Overtightening    of     the unloader    nut    will    result    in    damage    to    the unloader assembly. 17. Remove the alignment rod inserted in step 15. 18. Reinstall the governor control line to UNL port in center of unloader nut. 19. Reinstall   in   air   input   line   from   the   air   com- pressor. 20. Connect electrical lead for the heater. 21. Test unit using the instructions listed in SERVICE CHECKS. Servicing Deflector Assembly There  are  several  indications  which  may  mean that the deflector assembly needs servicing: Compressed  air  was  cooled  by  the  unit  but  no longer is cooled properly. Water exhausted by the CR BRAKEMASTER is brownish or brown particles are exhausted. A piece of the deflector is caught in the unloader valve     assembly     causing     it     not     to     operate properly. These    situations    can    be    caused    by    several conditions. Check the TROUBLE SHOOTING GUIDE to make  sure  that  the  probable  cause  is  a  malfunctioning deflector   assembly.   If   it   is   a   malfunctioning   deflector assembly, the following are the instructions for replacing this deflector assembly. Refer to Fig. 25 for numbers in parenthesis. 1. Refer to General Instructions. 2. Disconnect  air  compressor  service  line  at  inlet port. 3. Disconnect  governor  control  line  from  unloader nut (Item 27 of Fig. 23). 4. Disconnect wire from heater assembly. Fig. 25 Contents of Deflector Kit 1 Deflector 2 Body Tube 3 Rod, Support  Assy. (Refer to 4 Plate, Mounting 5 Gaskets 5. Remove  the  eight  cap  screws  (Item  13  of  Fig. 23) retaining bottom cap to body (2). 6. Remove bottom cap and deflector assembly. On older units the deflector is secured to the bottom cap. If    this    is    the    case,    the    deflector    should    be removed   from   the   bottom   cap   by   means   of removing the four screws holding the deflector to the  bottom  cap.  The  feet  of  the  bottom  cap  (to which    the    deflector    was    attached)    must    be removed. 7. Remove all traces of old gasket(s) material from gasket    surfaces    of    bottom    cap    and    body. Discard old gaskets. Be careful not to scratch or mar gasket surfaces. 8. Wash    bottom    cap    and    inside    of    unit    with cleaning solvent. 9. Position   new   gasket   (5)   on   top   of   surface   of deflector mounting plate (4). 10. Position    second    new    gasket    (5)    on    gasket surface of bottom cap. 11. Align  bolt  holes  and  position  assembly  against bottom  gasket  surface  of  body  tube  (2).  Use  of gasket sealant is NOT recommended. CTS-4079 - CHAPTER XIV - Page 16
