CAUTION; DO NOT adjust the wastegate so that
higher pressures are required to open the waste-
gate valve. The turbocharger speed will be
increased and can cause damage to the turbo­
charger and cause a loss of engine performance.
(1) Connect regulated air pressure to the waste-
gate actuator (Fig. 39). Install a dial indicator to
measure the control rod movement. Apply 103 - 138
kPa ( 1 5 - 2 0 psi) to seat the components and take
any slack out of the control rod. Release the air pres­
sure and zero the dial indicator gauge.

(2) Apply 133 kPa (19.3 psi) air pressure to the
actuator. The control rod should move 0.33 - 1.27 mm
(0.013 - 0.050 in) total travel. I f the rod travel is out
of limits, the wastegate linkage must be adjusted.
(3) To adjust the wastegate linkage, apply air pres­
sure to the actuator to release the spring tension on
the lever. Remove the control rod from the wastegate
lever (Fig. 40). Pull the wastegate lever toward the
actuator (closed position).
(4) Adjust the length of the clevis end of the con­
trol rod to align the clevis pin hole to the wastegate
lever. Install the adjusting link and retaining clip
(Fig. 40).
CAUTION: DO NOT pull, push or force the align­
ment of the clevis pin.
(5) After the adjustment is complete, tighten the
actuator rod jam nut.
(6) Recheck the travel on the wastegate control
rod. Adjust, i f necessary.
