ARMY TM 9-2815-255-24 AIR FORCE TO 38G1-95-2 MARINE CORPS TM 2815-24/4 FIGURE 3-114.  Balancer Shaft Bushing Line Boring References d. Apply a liberal amount of clean engine lubricating oil (MIL-L-2104) to bushings (16) in engine block and to balancer shaft (13 and 14) journals. CAUTION Do not intermix shafts (13 and 14) or gears (11 and 12) in location from which they were removed. Shafts are lapped for one direction of rotation, and exchanging locations could cause premature wear  of  shafts  and  bushings.    If  doubt  exists  as  to  which  shaft  Is  left  or  right-hand,  always replace the balancer shaft bushings (16). e. Install balancer shafts (13 and 14) and thrust plates (9 and 10). t. Secure each thrust plate (9 and 10) with two capscrews (7) and new lockwashers (8).  Tighten capscrews to 35 ft- lbs (47 Nm). g. Time balancer shafts as follows: (1) Turn right (camshaft side) balancer shaft (14) so timing mark is under timing tool (JD-254).  Timing mark on both balancer shaft gears (11 and 12) must align with centerline of crankshaft when correctly timed. (2) Install  lower  idler  gear,  and  without  turning  balancer  shaft,  secure  gear.    Spring  pin  must  enter  hole  in washer when it is installed. (3) Install  new  bolt  with  washer  from  oil  pump  side  and  new  nut  on  front  plate  gear  side.    Secure  nut  with adhesive (LOCTITE 242) and tighten to 70 ft-lbs (95 Nm).  Stake nut to capscrew by applying three center punch marks. 3-166
