Actuator Pod Removal - Polaris RZR XP Turbo Service Manual

4. With the use of an air regulator and pressure gauge,
attach an air supply line to the actuator pod pressure
reference port, located on the top of the canister.
5. Slowly apply pressure to the actuator, and watch the
indicator dial. Once the indicator dial has indicated a
displacement of .070" (1.75 mm), observe the line
pressure reading after the air pressure regulator.
NOTE
The intended actuator preload should result in a
displacement of .070" (1.75 mm) at 7 PSI supplied air
pressure. Having a correctly preloaded actuator will
help ensure correct turbocharger response and boost
pressure.
6. To adjust actuator preload, start by loosening the two
(13mm) lock nuts on the actuator rod, keeping in
mind the actuator rod itself is a left hand thread.

7. Using the same method of applying air pressure to
the canister as previously mentioned, the large
turnbuckle can be turned to adjust actuator preload,
until the desired preload is met. This correct preload
will result in .070" (1.75 mm) of displacement on the
wastegate flapper at a supplied pod pressure of 7
PSI. The nuts may be locked in place once again
using the (17mm) flats found on the actuator rod
turnbuckle.
NOTE
The preload may change when the lock nuts are
torqued. Ensure the correct preload is still measured
after locking the actuator rod turnbuckle in place.

ACTUATOR POD REMOVAL

1. Locate the actuator rod heim joint, located opposite to
the actuator pod.
2. Holding the opposite 13mm hex nut, loosen the bolt
securing the heim joint with a 4mm Allen key.
3. Remove both pieces to free the Heim joint from the
assembly.
