HEAVY DUTY ALTERNATORS Figure 22 - Removing Slip Ring Assembly. 3. Clean  the  rotor  shaft  and  apply  a  small  amount of Loctite "Sleeve N’ Bearing Mount" to the shaft on the section normally occupied by the slip ring assembly. 4. Position the new slip ring assembly on the shaft so  that  the  two  leads  are  aligned  with  the  two rotor coil eyelets on the rotor, and carefully press the slip ring assembly onto the shaft. There is no stop on the shaft to prevent the slip rings   from   being   pressed   on   too   far.      It   is therefore  necessary  to  press  the  slip  rings  only to  a  point  where  there  is  9.5  mm  (3/8")  space between the inner edge of the slip rings and the rotor (See Figure 23). Figure 23 - Slip Ring Locating Dimension. REASSEMBLY 1. If slip ring end bearing has been removed, press a  new  bearing  in  place  from  the  outside  of  the housing.    Bearing  should  be  installed  with  seal facing    in    toward    slip    rings.        When    properly installed, the manufacturer’s part number stamped on the end of the bearing will be facing toward   the   outside   of   the   housing.      Bearing should  seat  against  lip  on  inside  end  of  bearing bore.    After  bearing  is  installed,  apply  a  small amount of grease (Chevron SRI 2 or equivalent) to rollers. 2. Reinstall heat sinks in slip ring end housing.  Be sure that upper and lower insulating washers are in their proper location.  Install but do not tighten lower  heat  sink  retaining  screws,  lockwashers, guardwashers     and     insulating     washers     (See Figure  10).    Replacement  heat  sinks  may  differ in   thickness   or   appearance   from   the   original assemblies, but will fit and function interchangeably. 3. Install   terminal   bolts   and   regulator   lead   wires. Red  wire  goes  on  positive  heat  sink  and  black wire   goes   on   negative.      Be   sure   that   mating surfaces  of  heat  sinks,  terminals  and  terminal bolts are clean and free of paint to insure a good electrical connection (See Figure 8). 4 Install  two  insulating  bushings  on  each  terminal bolt  and  install  regulator  housing.    Be  sure  that red and black regulator leads are properly routed through   cutaway   section   of   end   housing,   and install  and  tighten  nuts  on  terminal  bolts  (See Figure 4). 5. Tighten  lower  heat  sink  screws   and   check   all leads for proper routing, being sure that no lead is pinched under heat sink. 6. Reinstall capacitor. 7. Reinstall stator and terminal nuts.  It is advisable to    align    stator    and    housing    by    temporarily installing the through bolts. 8. Press    drive    end    bearing    into    housing    and reinstall bearing retainer and four screws.  When installing  bearing,  press  on  outer  race  to  avoid transmitting    force    through    the    bearing    balls which could brinnell the bearing. 9. Press drive end housing and bearing on to rotor shaft.  Using a sleeve around the shaft, press on the inner race to avoid brinnelling the bearing. 10. Install   rotor   and   housing   assembly   into   stator and  slip  ring  end  housing  assembly,  being  sure that mounting ears are aligned. 11. Install  three  through  bolts  and  self  locking  nuts. Torque to 5.6-6.8 Nom (50-60 in.  lbs.).  Place a small   amount   of   grease   (Chevron   SRI   2   or equivalent)   in   housing   and   reinstall   the   metal dust cap by carefully pressing it into place.
