Task Instructions
1. Remove engine cowling. (Remove Engine Cowlings) It is necessary to access the engine throttle lever inside the cockpit and the cable lever on the engine. (Figure 376)
Figure 376. Throttle Assembly
Figure 377. Throttle Assembly—Exploded View.
Note:
ASN 00049 and below use a different THROTTLE CABLE BRACKET than shown.
2. Remove throttle bezel. (Throttle Handle and Bezel Removal)
3. Have a helper in the cockpit move the throttle forward and backward to confirm if the cable is clear and free to move.
4. Check that the throttle cable is secured and connected appropriately to throttle lever. (Figure 377 Figure 380)
5. Clear and remove any obstructions that would prevent cable from moving.
6. Check in the idle position that the throttle lever has at least 0.50 inches of clearance to full travel.
◦ In cockpit, retract throttle handle to contact AFT stop (idle position). At engine, ensure lever idle stop contacts idle adjustment screw at the same time or just before the throttle handle contacts the aft stop. (Figure 378)

7. Check in the full throttle position that the throttle lever has at least .050 inches clearance.
◦ In cockpit, move throttle handle to full throttle position (FWD stop). At engine, ensure the lever full throttle stop contacts the throttle body before the throttle handle contracts the FWD stop. (Figure 379)
Note: 
The throttle lever on the engine is spring loaded to the full open position.
8. Adjust position of cable in cable fixation fastener as required. (Figure 380)

9. When cable adjustment is complete, torque jam nut to 45±5 in-lb.
10. When cable adjustment is complete, torque cable fixation fastener to 35±5 in-lb. Check that hardware is secure.
11. Inspect for any loose bolts. (Figure 377)
12. Replace throttle bezel. (Throttle Handle and Bezel Removal)
13. Replace engine cowl. (Remove Engine Cowlings)
