Checking spinner tracking is part of normal maintenance.
Locate a fixed object on a flat floor to just clear the lower edge of the tip of the Spinner.
Rotate the propeller by hand and check that the Spinner runs true.
Spinner tracking can be adjusted by loosening the mounting screws, moving the tip in the
required direction and re-tightening.
If required, spinner balance can be checked by removing the spinner and balancing it on a
sharp probe positioned inside the centre of the spinner tip. Balance can be adjusted by adding
weight as required. Contact Jabiru Aircraft or our local approved representative for details.
Note: spinner balancing is not a part of normal maintenance. It is provided for reference
purposes & for troubleshooting vibration.

Inspect ducts for damage or wear.
If the hard-points where the ducts screw to the engine are damaged they must be repaired by
the installation of reinforcement as shown in Figure 32:
While the duct is sitting on the engine position the reinforcement as shown and mark the two
rivet holes.
Drill duct to suit and rivet the reinforcement in place.
