YUKON 208 PROPELLER INSTALLATION GUIDE

the orientation of the propeller pins on the prop shaft. The PT6 on this installation utilizes the N flange as referenced in Hartzell Owners Manual 147, Figure 3-5 For Reference Only 29 Apply Hartzell provided anti-seize compound PN A-3338 to threaded studs on prop. This is typically provided with your new propeller. Align the Yukon prop in the correct orientation to the prop shaft dowell pins For Reference Only 30 Make note of washer, nut, and O ring reference as noted in Hartzell Owners Manual 147, Chapter 3, Figure and Table 3-1 as referenced below. Orientate washers accordingly For Reference Only 31 Torque per the installation instructions found in Hartzell Owners Manual 147, Section 3, Table 3-2 utilizing torque adapter PN AST- 2877-3. Torque per sequence found in Figure 3-3. For Reference Only 32 For Reference Only 33 Safety wire or Safe-T-Cable to secure prop nuts after torque sequences. Do not allow pig tails or cable crimps to protrude outwards. This may result in undesirable contact with the beta bracket as it moves forward and aft. Note: Highly recommended to use Safe- T-Cable over safety wire Incorrect Correct Beta bracket movement of travel For Reference Only 34 SUGGESTED SAFETY CABLE TOOL WWW.DMCTOOLS.COM For Reference Only 35 Important-While you CAN use safety wire, it will be very difficult to access the nuts adequately and wire cleanly, let alone keep the wire away from beta ring. Extremely tight area For Reference Only 36 SPINNER DOME INSTALLATION For Reference Only 37 Installation of spinner dome is performed per Hartzell Owners 143, Section 3, Par 5 as shown below For Reference Only 38 Spinner PN 107196P is used in all propeller configurations Support bulkhead PN C-5324 is used in all propeller configurations For Reference Only 39 Installation of the FWD spinner bulkhead PN C-5324 onto hub as shown below may require Hartzell Propeller Tape PN B- 6654-100 to be installed as shim material for shimming radially (side to side) There is an optional use of this same tape between bulkhead and spinner dome as noted in Par D and Figure 3-18 shown below. For Reference Only 40 You are trying to achieve a fitment using supplied spacers with spinner to backplate hole misalignment as shown in Figure 3-17 Below. For Reference Only 41 Gently and evenly install the spinner. Once holes are aligned start with the center holes first in all four spinner quadrants. Once these center four screws are installed, work outward on the remaining 4 screws. 1 2 3 4 Fiber Washer PN A-1020 Screw 10-32 PN B-3845-8 For Reference Only 42 SPINNER IPC REFERENCE HERE- PENDING FROM HARTZELL For Reference Only 43 BETA FEEDBACK ARM For Reference Only 44 Installation of the reversing linkage arm is accomplished using 3 different data sources. 1.

THE YUKON PROPELLER INSTALLATION CHANGES A SINGLE RIG POINT, HOWEVER THAT CHANGE MAY AFFECT OTHER RIGGING POINTS. BE PREPARED AND FAMILIARIZE YOURSELF WITH RIGGING A PT6 (-114A AND -140 AS APPLICABLE) PRIOR TO THIS PORTION OF YOUR YUKON PROPELLER INSTALLATION. For Reference Only 65 WIPAIRE INSTALLATION DRAWING 1012329 Pay particular attention of notes shown on LH side of drawing for rigging points. For Reference Only 66 https://www.youtube.com/watch?v=H7c2NiFCNHo If the assumption is made that the engine is properly rigged prior to previous propeller removal, only one parameter is required to be changed on the PT6A-114A installation. This can be found in the video below, reference the 12:18 point of the video. NOTE: By adjusting the low idle NG per note 7, other parameters of the engine rigging may change. Be wary of completing a single adjustment and expecting all other rigging to hold properly. For Reference Only 67 https://www.youtube.com/watch?v=0pApxlmLiMw If the assumption is made that the engine is properly rigged prior to previous propeller removal, only one parameter is required to be changed on the PT6A-140 installation. This can be found in the -140 video below, reference the 14:35 point of the video. NOTE: By adjusting the low idle NG per note 8, other parameters of the engine rigging may change. Be wary of completing a single adjustment and expecting all other rigging to hold properly. For Reference Only 68 Reversing cam reference as noted below. For Reference Only 69 PERFORM FULL ENGINE RUNS WITH RIGGING CHECKS USING VIDEOS SHOWN AS A GUIDE. ENSURE THAT ALL STOCK PARAMATERS ARE BEING HIT INCLUDING THE INCREASED LOW IDEL NG PER WIPAIRE DRAWING 1012329 FOR YOUR INSTALLED ENGINE (-140 OR -114A) AND RIG AND ADJUST ACCORDINGLY.
