YUKON 208 PROPELLER INSTALLATION GUIDE

deice kit, TKS bracket, etc… Verify all paperwork serial numbers match the actual propeller that was shipped. 25 Using the CST-2987 Beta Ring decompression tool, configure the puller as shown below. • PN 2987 Puller • PN 2987 + 7 Rods (4e) • PN 106788 Ring • Misc required hardware for attachment x x • Not used 26 PN 2987 PN 2987+7 BETA RING PULLER PN CST-2987 27 Install Beta Ring decompressing tool to propeller utilizing plate PN 106788 and related misc hardware as shown. • Install NAS1149F0963P (AN960-916) washer between beta ring and prop as shown to provide stability to swivel. 28 29 Install new prop flange O ring seal, this will be in your new prop kit. 30 Important! Locate 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 31 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 32 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 33 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. 34 35 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 36 SUGGESTED SAFETY CABLE TOOL WWW.DMCTOOLS.COM 37 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 38 SPINNER DOME INSTALLATION 39 REFERENCE HARTZELL SPINNER PARTS BREAKDOWN PER HARTZELL MANUAL 127, REV 26 OR LATER 40 REFERENCE HARTZELL SPINNER PARTS BREAKDOWN PER HARTZELL MANUAL 127, REV 26 OR LATER TKS CONFIGURATION DEICE AND PLAIN CONFIGURATION 41 INSTALLATION OF SPINNER DOME IS PERFORMED PER HARTZELL OWNERS 143, SECTION 3, PAR 5 AS SHOWN BELOW 42 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. 43 You are trying to achieve a fitment using supplied spacers with spinner to backplate hole misalignment as shown in Figure 3-17 Below. REF NEXT SLIDE 44 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. 45 NOTE: There may be slight spinner to nose cowl clearance issues. You may have to adjust the RH nose cowl bracket at this location to achieve sufficient space needed for clearance. You may also have to elongate holes slightly and reposition bracket if more clearance is needed. In the photo below, note the tightest area is typically just above oil cooler opening on RH cowl half 46 BETA FEEDBACK ARM 47 Installation of the reversing linkage arm is accomplished using 3 different data sources. 1. Hartzell Owners Manual 147, Section 3 and Figure 3-7 for fitment of the block into the beta ring and ONTO the arm 2. Cessna Maintenance Manual 60-10-00 and 61-20-00 3.

REFERENCE WIPAIRE DRAWING 1012329 (REV B OR LATER) FOR INSTALLATION AND BUILD UP REFERENCE 63 ENGINE RIGGING HIGHLIGHTS 64 THIS OPERATION WILL REQUIRE AN ADVANCED AMOUNT OF KNOWLEDGE FOR RIGGING THE PT6 TO FACTORY SPECIFICATIONS. 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. 65 WIPAIRE INSTALLATION DRAWING 1012329 Pay particular attention of notes shown on LH side of drawing for rigging points. 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. 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. 68 Reversing cam reference as noted below. 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. PERFORM INSPECTION AND ENSURE ALL SAFETY WIRE, COTTER PINS, ETC.. . ARE REINSTALLED UPON RIGGING COMPLETION 70 WEIGHT AND BALANCE NOTATIONS 71 NOTE: WEIGHTS AND ARMS APPLY TO BOTH THE 208B GRAND CARAVAN AND THE SHORTER 208.
