13. Ensure the sensor wire is supported as close to the sensor pick-
up as possible. Flight loads may cause stress and damage to the
wire where it enters the sensor body.
14. Make sure the cowl is secured to the airplane and that the
spinner to cowl clearance is at least 3.2mm [1/8"]. If starting the
engine the fi rst time and during break-in it’s recommended that
you run the engine without the cowling.
Drill and Install the Propeller
The easiest way to drill the propeller to fi t the hub is to use a DLE
drill guide (DLEQ1111). If you do not have a drill guide, you can
use the following method to drill your propellers. Most propellers
within the recommended size range have a 0.393" [10mm] center
hole pre-drilled. If your propeller has this predrilled hole, move on
to step 3. If not, start with step 1.
1. Remove the cowling from the aircraft. Use the included propeller
washer to mark the centering hole on the propeller.
2. Once the location is established, use a drill press with a #5
(.2055" / 5.21mm) drill bit as a pilot hole. Once the pilot hole is
established use a 13/32" (.406 / 10.31mm) drill bit to fi nish the hole.
In order to achieve a clean opening on both sides of the propeller,
drill only half way through the propeller with the fi nishing drill bit.
Then fl ip the propeller over and drill completely through the hole.
3. Next, set the engine at the
beginning of the compression
stroke. Note the position of
the ignition magnet.
