Fig.  72  Air Injection System Used on Small V8 Engine (For California)
ENGINE DIVISION SERVICE MANUAL TM 5-4210-230-14&P-1 Fig.  71  Air Injection Pump With Diverter Valve (Except California) (1) Disconnect   left   bank   air   injection   hose   from   air manifold  check  valve  and  connect  air  pump  output tester SE-2498 to end of hose. (2) Disconnect  left  bank  pressure  limiting  hose  from  air cleaner and plug end of hose. (3) Connect tachometer to engine. (4) Operate   engine   at   speed   specified   (see   Emission Control Tune-Up Specifications) (5) Observe pressure indicated.  If air pressure does not exceed minimum specification (see Emission Control Tune-Up  Specifications)  perform  the  following  steps a, b, c and d. a. Check   air   hoses   for   leaks.     Check   diverter valve  for,  external  leaks.    If  leaks  are  found, replace   hose(s)   and/or   diameter   valve   and repeat steps 4 and 5. b. Disconnect   air   hose   (connecting   air   pump outlet   to   diverter   valve   inlet)   from   diverter valve and connect air pump output tester SE- 2498 to end of hose. c. Operate    engine    at    specified    speed    (see Emission Control System Tune-Up Specifications) and observe minimum pressure. (1) If  air  pressure  is  less  than  specified  minimum  (see Emission  Control  System  Tune-Up  Specifications), air  pump  is  faulty  and  must  be  replaced.    When installing  a  new  air  pump  or  adjusting  the  air  pump belt tension, do not pry on the pump housing. (2) If    air    pump    pressure    is    higher    than    specified minimum   (see   Emission   Control   System   Tune-Up Specifications),  diverter  valve  is  faulty  and  must  be replaced. d. Connect air pump output tester SE-2498 to air injection   hose   removed   from   check   valve. Connect  air  injection  hose  from  air  pump  to diverter valve inlet and repeat steps 4 and 5. (6) With    the    engine    operating    at    speed    specified, observe   the   pressure   gauge.      Multiply   observed pressure    by    .7    to    obtain    multiplied    pressure. (Example:  Observed  pressure  is  6  PSI  and  multiply by .7.  6 x .7 = 4.2 PSI multiplied pressure) (7) Remove   plug   in   the   pressure   limiting   hose   and observe the pressure gauge. a. If  observed  pressure  in  step  7  is  higher  than multiplied pressure in step 6, diverter valve is acceptable for further use. b. If  observed  pressure  in  step  7  is  lower  than multiplied pressure in step 6, diverter valve is faulty and must be replaced. (8) With  the  engine  operating  at  speed  specified  (see Emission  Control  System  Tune-Up  Specifications), remove vacuum hose from diverter valve and check for vacuum pull at the end of the hose.  If no vacuum is felt, check for restriction in vacuum hose, vacuum manifold  and  carburetor  vacuum  port.    Repair  as needed.
