FITTING YOUR GEN V WASTEGATE
Mounting your New Turbosmart Gen V IWG
Wastegate
1
Slide the actuator head through the mounting bracket, be sure
the ball joint assembly has been removed from the actuator
canister otherwise the unit cannot be assembled onto the
bracket. Once mounted on the bracket, secure nuts to hold
actuator in place, be sure at this point to determine the orientation
of the actuator as it can be flipped 180º on the actuator bracket
to allow for fitting clearance, or aligning the actuator to your liking
without need to disassemble the actuator.
CAUTION!
Ensure nuts are tightened
Applying Actuator Preload / Ensuring
Wastegate Flap is Closed
3
CAUTION!
This step is important
In order to ensure the actuator does not suffer any
stiction/temperature creep issues or the wastegate flap does not
stay slightly open, it is important to apply a small amount (2mm/
0.078”) of preload to the wastegate actuator.
To correctly preload the wastegate, ensure wastegate flap is in
the full closed position by holding the actuator flap as far closed
as possible, wind the adjuster nut onto the back face of the
actuator flap as shown below until hand tight
Figure 3 – Install Actuator through bracket
To apply (2mm/0.078”) preload, simply turn the adjuster nut 2 full
turn in the clockwise direction.
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)

If a regulated air source is available on-hand, apply the air
pressure of the spring installed to the actuator (5, 7 or 14psi) and
observe the rod, the rod 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
troubleshooting.
Install the ball joint
2
Once the actuator has been mounted to the bracket, install the
ball joint onto the main shaft out the actuator, orientation of the
ball joint is not important. Use the flats machined into the ball joint
to hold the ball joint in place as you tighten the nut on the main
shaft to prevent unnecessary movement of the ball joint during
operation.
Start Engine and Check for Leaks

Congratulations, your Gen V wastegate is installed and ready for
use. Double check all fittings, lines and mountings then proceed
to start engine and check for leaks.
