ENGINE DIVISION SERVICE MANUAL TM 5-4210-230-14&P-1 ENGINE 60.   Place  the  water  pump  pulley  on  the  shaft  and  install  V- belt   over   crankshaft,   water   pump   and   power   steering pulleys. 61.   Install  freon  compressor  bracket  to  right  cylinder  head. Refer to Figure 20. 62.   Place freon compressor on bracket and secure it with four bolts and lockwashers. 63.   Install idler pulley bracket on freon compressor with bolts and washers. NOTE:   The   bottom   two   bolts   utilize   two   hardened washers each.  Refer to Figure 18. 64.   Install   air   pump   mounting   bracket   and   adjusting   strap with spacer on right side of freon compressor. 65.   Install  air  pump  loosely  on  bracket.  Place  V-belt  on  air pump and freon compressor pulleys.  Connect air hoses between  air  pump  and  air  manifold  check  valves.    Refer to Figure 16 for location. 66.   Install V-belt on freon compressor, idler, water pump and crankshaft pulleys. 67.   Place  alternator  bracket  and  adjusting  strap  in  position and secure with bolts and flat washers. 68.   Install    alternator    loosely    in    position    on    bracket    and adjusting strap.  Install two V-belts alternator, water pump and crankshaft pulleys. 69.   Place air compressor bracket with "O"-ring in position and secure with bolts and washers. 70.   Place  air  compressor  with  gasket  in  position  on  bracket and  secure  with  bolts,  nuts  and  washers.    Install  water return,  water  inlet,  air  inlet  and  oil  feed  lines.    Refer  to Figure 8 for proper locations. 71.   Install V-belt on air compressor and water pump pullys. 72.   Place  fan  blade  and  spacer  in  position  and  secure  with bolts and lockwashers. 73.   Adjust all belts to proper tension according to "Accessory Drive Belts" in CLEANING, INSPECTION AND RECONDITIONING. 74.   Install low temperature vacuum control valve and exhaust gas recirculating valve hoses if so equipped. 75.   Install engine front mounting bracket. 76.   Attach suitable hoisting equipment to the lifting eyes and apply   sufficient   pull   to   support   the   engine   assembly. Remove   the   engine   overhaul   stand   bracket   from   the engine. Accessory Drive Belts Conventional    "V"    belts    are    utilized    to    drive    the various  accessories.    Four  belts,  driven  from  the  crankshaft pulley,  drive  the  freon  compressor,  alternator,  water  pump, fan  and  power  steering  pump.  Another  belt,  driven  from  the water  pump  pulley,  drives  the  air  compressor  and  another belt,  driven  from  the  freon  compressor  pulley,  drives  the  air pump.  Engines having dual belts driving the water pump and alternator should have the belts replaced in matched pairs. Alternator belt tension can be accomplished with the use    of    SE-2312    gauge,    Figure    156.        Check    tension    at midpoint between the pulleys.  Apply gauge to the longest belt span.  Instructions for checking are as follows: 1. Grasp  gauge  and  depress  ball  handle  all  the  way  down. Make  certain  hook  extends  beyond  legs  to  pick  up  the belt. 2. Apply    gauge    to    belt,    Figure    156.        Be    sure    belt    is positioned  between  nose  piece  and  hook  and  that  the nose piece is centered on the belt. 3. Release ball handle quickly.  A slow release may prevent full return of the hook, thus giving a false reading. 4. Observe the area of the gauge face indicated at the index mark.  If the index mark does not indicate a NEW reading on a new belt, or a USED reading on a used belt, it will be necessary    to    increase    or    decrease    belt    tension    as required. 5. Before changing belt tension, repeat Step 3 several times to become familiar with gauge operation.  Observe gauge reading each time the operation is repeated. NOTE:     Check     tension     of     both     belts     when     so equipped. CGES-210  Page 64 PRINTED IN UNITED STATES OF AME RICA
