VACUUM REGULATOR VALVE ADJUST

NOTE: During the check and adjustment procedure, the engine must not be operating.

1.Disconnect two port vacuum connector from vacuum regulator valve located on the left side of the fuel injection pump.
2.Disconnect throttle cable from throttle lever.
3.Remove throttle return spring. Install end of spring over throttle lever ball stud and other end of spring over throttle cable support bracket.
4.Connect a suitable vacuum pump to the upper port of the vacuum regulator valve (vacuum supply side).
5.Connect a suitable vacuum gauge to lower port of vacuum regulator valve labeled TRANS.
6.Apply and maintain 20 in Hg of vacuum to the vacuum regulator valve. It will be necessary to pump the vacuum up as it bleeds off. Cycle the throttle lever 5 times from idle to the wide open throttle position with vacuum applied.

7.Insert gauge block No. T83T-7B200-AH (0.515 in) between pump boss and throttle wide open stop. The throttle return spring as repositioned previously, will hold the throttle lever stop against the gauge block tool. The vacuum gauge should indicate 6-8 in Hg of vacuum. If reading obtained is not as specified, adjust vacuum regulator valve as follows:
a.Loosen two adjustment screws attaching vacuum regulator valve to the fuel injection pump.
b.Rotate vacuum regulator valve until correct vacuum reading is obtained, then torque the two adjustment screws to 75-90 in lbs.
c.If vacuum regulator valve cannot be adjusted, replace vacuum regulator valve and repeat adjustment procedure.
d.Remove gauge block tool.
e.Connect throttle return spring and throttle cable.
f.Apply 20 in Hg of vacuum to the vacuum regulator valve and while maintaining vacuum, cycle throttle lever from idle to the wide open throttle position 5 times. The vacuum gauge should indicate at least 13 in Hg (throttle at idle position).
g.If vacuum gauge indicates less than 13 in Hg the vacuum regulator valve must be replaced and the new valve adjusted.
h.After necessary adjustment procedure has been completed, remove vacuum pump and gauge from vacuum regulator valve. Reconnect vacuum connector.
i.Start engine and check operation of throttle. Check transmission shifts.
