Task Instructions
1. If required sub-assemble 2 each engine cooling fans with 6 X screws (6C62MTF3-100), 1 cooling fan half (ICA005858), 6 X nut (MS21043-06), 6 X washer (NAS1149CN632R), and 1 backing plate half (ICA11499). Ensure backing plate is oriented with beveled edge facing away from cooling fan. (Figure 483)
Figure 483. Cooling Fan Half Assembly
2. Torque 12X fasteners to 9 in-lbs.
3. Install 1 propeller extension (6-IN Rotax) and cooling fan onto propeller flange using 6 X bolt (AN5C20A), 6 X bushing (ICA012162), 6 X nut (MS21043-5), 6 X washer (NAS1149C0563R). Figure 484

4. Apply lubricant (ICA012078) to the surfaces indicated in Figure 485.
CAUTION: 
Rotate engine in counterclockwise direction ONLY.

5. Ensure fan is oriented with the blades pointing away from the engine.
6. Torque 6 X bolts according to sequence in
CAUTION: 
Rotate engine in counterclockwise direction ONLY.

7. Ensure propeller hub is seated flush against propeller extension flange.
8. Apply torque stripe.
9. Place spinner bulkhead onto propeller extension. (Figure 487)
Figure 487. Spinner Bulkhead Attachment
10. Install propeller onto spinner bulkhead as shown using 6 X bolts (AN5C34A), 6 X washer (NAS1149C0563R), on the bolt head/propeller hub side, 6 X washer (NAS1149C0532R), 6 X nut (MS21043-5).
11. Apply lubricant to bolt shanks and under washers where they contact the propeller and propeller extension flange. Fasteners should be slightly snug. Do not torque.
12. Torque 6 X bolts according to Figure 488.

13. Ensure propeller hub is seated flush against propeller extension flange.
14. Don’t apply torque stripe. Torque stripe should be installed at the end of propeller balance. (Balance Propeller)
15. Perform propeller pitch check.
Verification Method
Perform dynamic propeller balancing. (Balance Propeller)
