Familiarise Yourself with Cap and Body
closed as possible, wind the eyelet in to ensure that the correct
amount of preload has been applied.
To apply 1mm/0.039” preload, simply turn the adjuster eyelet
full turn in the clockwise direction.
Locate cap and body notches and grooves which dictate the
alignment of the cap. These notches are used to locate the
cap onto the body and must be aligned prior to compression
of the cap onto the body
To lock the actuator in this position, turn the locking nut by
hand until finger tight, then proceed to tighten nut firmly to
secure actuator in place. (6.5Nm / 4.8 ft lb)
Ensure notches are aligned and seated home correctly
prior to exerting force to tighten collar, permanent
damage will occur if these are not aligned correctly.
If a regulated air source is available on-hand, apply the air
pressure of the spring installed to the actuator and observe the
linkage, the linkage should begin to move slowly and freely
over the range of travel as air pressure increases. If the rod
does not move at all with increasing air pressure, proceed to
Press Cap onto Bod
Using a press or vice, comp
ensuring the notches are remain
seated home onto the body, scr
a clockwise direction. While stil
the collar further with the collar tool until the collar will not turn.
Reinstall Gen V Wastegate
Install wastegate actuator assembly to bracket
Install rod to straight gate
Apply wastegate preload
Lock adjuster nuts
Connect wastegate signal lines and check for leaks
Maintain downward pressure on cap while tightening
collar or non-repairable thread damage will occur.
If an adjustable air source is available, connect to signal ports
and check for smooth free operation of wastegate, if
wastegate does not move with increasing air pressure,
proceed to troubleshooting.
Reinstall fittings to the cap of the wastegate using fresh
Loctite 567 thread sealant.
Turbosmart sets preload from factory and should only
need to be set after changing springs.
To correctly preload the wastegate, ensure wastegate valve is
in the full closed position by holding the actuator valve as far
