Instructions for Printing & Binding

Delete this page before printing

This page gets wasted even though it is printed, to maintain orientation of pages throughout the manual. Print on 20 Lb. Premium Paper or better. I prefer Spiral Bound with Clear Front Cover and Heavy Black Back Cover. This allows the manual to be opened and folded back leaving the desired page exposed and lays flat when opened to expose 2 pages while doing Inspections or Maintenance. This allows a blank page for making notes. I generally get them printed at Staples or Office Depot where it costs as little as $15.00 USD per manual. Some of the pictures are in Color for online viewing, but we print them in black & white except for the Cover. Be Safe & have Fun!!

Press Block and Undersize Dowel for pressing dowels out when replacing bearings.

Tools needed: Torque Wrench (Inch Pound), Offset Phillips Screw Driver, 3/8” X 7/16” sockets and wrenches and Plastic Face Hammer or Hard Rubber Mallet.. 10 ton Press. Note: Never use a regular hammer to strike any part or fastener in the Slick Trim Assembly. Excessive force should not be required, all parts are machined fit. Gentle use of a plastic hammer should suffice. NEVER USE an impact driver to tighten nuts. Even small cordless impact drivers can over torque nuts. Use a cordless drill set on low resistance, 10 or 11 Something that simply snugs nuts prior to torqueing.

Assemble Side Plates and Actuator Plates, in opposite directions, for left and right sides. As shown above. Parts needed: 14 - MS24694-S59 or AN509-10R16 Countersunk Screw 14 – AN960-10 Washer Reg. 14 – AN365-1032 NyLock Nut Torque = 35 In.Lbs. Use 100 degree countersink if needed to assure flush screw heads.

8

Use of Press Block

Side Placement

Top Placement on wide Truck

On Narrow and odd size Trucks place block on an angle. This allows Truck to stand on Press Block while you press out one pin & Bearing at a time.

9

Assemble Truck with Bearings and Shims

Parts needed for Truck Assembly: 10 - Bearings #1614 McMaster Carr (MMC) # 2780T57 Sealed 10 – 3/8” by 0.010” or 0.007” Stainless shims McMaster # 98126A371 4 - 3/8” x 1” Dowel Pins MMC # 98381A624 6 – 3/8” x 2” .001” oversize Dowel Pins MMC # 98385A632 (Grind .015 to .020” off tapered end, all 6 ) NOTE: For Oversize Truck with 3 pins above and 3 pins MMC # 98385A634 cut and bevel to 2.235” long.

1 ) Press first dowel in flush with round end down, then press it in further with the second dowel. NOTE: ground ends together as they go in. Stop an release pressure occasionally to ensure straight push. 2 ) Place one .010” shim over dowel and press bearing and shaft down tight. Note: Have room (Press Block) under truck for Dowel to pass through. 3 ) Repeat until all 3 on one side are done.

4 ) Place shims and press bearings on second side Note: Use another dowel and insure that dowels are pressed slightly recessed into bearings. Check all 6.

10

5 ) Press 1” dowels into top about ¼”, then, with shim under bearing, Press in tight, all 4 6 ) Place Clevis Pin AN394-43 and Cowling Pin AN416-1 Note: The Clevis Pin is trapped when unit is fully assembled. Finish Slick Trim Assembly IMPORTANT: Refer to “Configurations 2” forward, aft or center & 3” page 13

Parts needed: 7 – AN3-47A Bolts (AN3-51A for Wide Version) 7 – AN960-10L Thin Washers 7 – AN365-1032A NyLock Nuts 2 – Stops ½” OD ¼” ID Anodized 1 – Actuator Rear Anchor 2 – AN4-47A Bolts (AN4-51A for Wide Version) 2 – AN960-416L Washers (Thin) 2 – AN365-428A NyLock Nut IMPORTANT NOTE: Insure Clevis Pin and Cowling Pin are installed in Truck as shown above. Clevis Pin is trapped when unit is assembled. Particularly the narrow trim. 1) Place the 7 - 3/16” (AN3) bolts ( 6 for Power Steering Option ) and 2 - ¼” (AN4) Bolts as shown then add 2 Stops and Actuator Rear Anchor as shown. 2) Place the Left side over bolts as shown, add appropriate washers (Thin Washers on AN4 Bolts and Thick (standard) washers on AN3 Bolts), and start nuts to finger tight.

11

3) Turn unit upright and drop Spacers into place leaving center bolt exposed as shown. 4) Torque 4 - 3/16” nuts on bolts that pass through Spacers to 40 Inch Lbs. 5) Torque remaining 3 – 3/16” nuts on bolts to 15 Inch Lbs. 6) Torque 2 – ¼” Nuts on AN4 Bolts on Actuator Rear Anchor, to 40 Inch Lbs. Setting Linear Actuator. Run actuator in electrically until it stops electrically. Be sure that actuator ends turns freely. Note: Insure that it has not stopped by running out of screw space.

Minimum 5/16” setting (shown in picture above). Dirt Guard to inside of hole.

12

Align hole to match angle of fixed hole on far end of actuator. NOTE: There must be 5/16” to less than 3/8” from the plastic dust sweeper to the inner edge of the ¼” hole. Note: any less than 5/16” will cause damage to the dust sweeper & can cause mechanical stoppage and screw jack damage. Use 12 VDC power to Run Actuator out and back in until it stops electrically and confirm measurement. To install Actuator:

Allow clevis pin to drop into bearing channel. Slide pin through actuator and insert Cowling pin. Note: The easiest way is to put actuator into position and turn unit over maintaining alignment. The pin will drop through when alignment is gained. Let gravity do the work, just gently move actuator until alignment is achieved, and the pin will drop through. Put cowling pin in to secure clevis pin.

Place PVC washer on each side of Anchor plate, and put AN4-47A through to secure actuator into position. With thin washer and nut, tighten to snug, 10 inch lbs.. NOTE: Wide Version changes to AN4-51A and each side of Anchor plate gets 2 AN4 thick washers on each end of steel tubes to get proper spacing. Connect electrical and cycle to insure full unobstructed movement of truck.

13

Actuator Guard ( Optional ) Guard is to protect the Actuator during wing setup and set down. Is installed with: 4 - AN3-5A bolts (AN3-6A and 2 thick washers between Guard and each side plate for spacing) 4 – Thin washers (outside of actuator plate under nuts) 4 – AN364-1032A Thin Nuts Torque to 35 inch pounds.

Configurations 2” forward, aft or center & 3”

14

Installation Instructions.

Installation shown on Northwing Apache, but can apply to many trikes and wings.

Place Collar 5/16” from forward most obstacle. We use 5/16” Hex Driver to establish space. Torque Collar with even spaces, to 144 Inch Pounds. Back and forth to keep even spacing.

15

Place Delrin Block into position, and move rear collar forward, use Feeler Guage and allow 0.025” space between Delrin Block and Rear Collar, and torque same as front Collar.

Install Slick Trim onto the Trike Mast Using the nylon spacers normally used on the trike Hang Block, or large Fibeer washers to Center the mast in the aluminium Truck. Use 3/8” bolt AN6-46 ( AN6-50 for Wide Version), 2 - spacers, 2 – Black Luster Washers and Castle Nut. Be sure to use spacers as shown (above left) in the safety groove. Order of assembly, put 1 Black Washer on bolt and a Spacer, put bolt in from right side of trike and push through hole in Truck while maintaining alignment and put other Spacer and Washer on, then Nut on the left side. Tighten Finger tight and install Cowling Pin.

16

Important Note: Use wiring harness and 12 Volt Battery to position Hang Bolt slightly Aft of Centre position. It is best to have wiring installed at this point. If this is the original installation, skip ahead to the wiring section and complete that first. Set Nose of wing on 3rd rung of step ladder to achieve proper wing angle

Roll Trike into position maintaining alignment. Release “Pull Down Rope” to allow Trim to move up into position

17

Insert 3 – 5/16” Bolts ( AN5-43) from the right side. Install Castle Nuts on left side, Finger Tight plus ( Like more than snug. ) whatever is needed to gain Cowling Pin alignment by light tightening. And install Cowling Pins.

Install 5/16” Northwing Safety Cable as shown, wrapping around Keel Tube in front of Down Tube Block. Both sides, using Spacers and AN5-47 Bolts furnished. Note: Make sure Stainless Tangs are bent out far enough to allow clearance of hang bolt as it moves fore and aft. Important Note: Run Trim to Aft position before raising the wing, this will allow more room to clear the nose of the Trike.

Wiring Diagrams Simple DPDT rocker switch

OR

Connect power leads

To Maximum 5 Amp. Protected circuit, Hotbox or fuse bar. White and Blue/White leads to Positive and Negative on Hotbox or Fuse bar. Connect outer shield Ground or Negative terminal not being used, to establish good ground to Engine.

If the Rocker Switch is working backwards Reverse the White and Blue/White leads at your power pick-up point, Hotbox, or Fuse Box. This will make the Rocker Switch run in the opposite direction.

19

Power Steering ( Option ) To get the Power Steering Option only the Side Actuator Plates (2 each) must be changed and add the Torque Bracket. This also requires 2 Split Spring Pins McMaster #92383A727 and remove top front countersunk screws. Also need an AN5 Bolt long enough to secure down tube brackets to Trim System.

Close Pins while keeping them round Press pins in with smooth jaw pliers

Finish pressing pin until it sticks through about 1/8” Full Assembly

Inspection Procedures and Intervals

Annual and/or 100 Hour Inspections

1) Remove Wing & Slick Trim from Trike, for partial Dis-Assembly. 2) Before taking Trim off trike, electrically retract Actuator to aft shutoff position. 3) Remove Guard & Actuator from Trim Assembly. 4) Replace Clevis Pin and Cowling Pin in Truck. 5) Remove 7 – Nuts and washers on long 5/16” Bolts and 2 – remaining ¼” Actuator support plate

Bolts, that secure both halves together. 6) Separate both outer halves and remove Truck. 7) Inspect entire Truck for Cracks or Wear. 8) Inspect Bearings for wear and roughness of operation. Replace if necessary. **Note Below. 9) Inspect Bearing wear surfaces in the Side Plate Tracks and where the Lateral Alignment bearings

run above Tracks. Bearing Tracks must be kept Clean and Oil Free. Replace worn parts as needed.

10) Inspect Entire Assembly for cracks or excessive wear. Note: Any cracks in Anodized Parts will require replacement.

11) Inspect all bolts you have taken off for wear, Replace as needed. 12) Inspect 3/8” (AN5) Hang Bolt for excessive Wear or Distortion. With the head of the bolt over

the edge of a flat surface, roll the bolt to insure that it is straight. Any wear in excess to 0.002” in depth, sharp grooves or bent bolts must be replaced with new.

13) Inspect Actuator Screw by operating. Put ¼” bolt through end to keep it from turning while operating. Excess resistance may indicate the actuator screw jack is worn or damaged. There should be no end play in actuator arm while extended. End Play in excess of 0.013” will require Actuator replacement.

14) Generally, Nylon Lock Nuts should only be used through 3 removals. Be sure they have not lost their gripping power.

** Note: Bearing replacement is best accomplished by shipping Truck Assembly back to Pitman Air or your Authorized Slick Trim Dealer. Or Special Dies & Tools used to press bearings out can be purchased through Pitman Air. Important Note: Cracks in Anodized Surfaces become stress concentrations and/or indicate excessive stress. These Parts must be returned to Pitman Air for inspection. Replacement parts will supplied at our cost, or free of charge under Limited Warranty. Please accompany these parts with The Serial Number (located on the front of the Truck), an explanation of hours of use and any unusual circumstances that may have added to the wear or cracks. Use “Safety of Flight & Service Difficulty Report Form” in the back of this manual to report problems.

Appendix A Wiring of Seat Rail Rocker Switch on Northwing Apache:

Install Rocker Switch on seat rail near back of Front Seat on the left side as shown or on the right side, using hose clamps. Note: Put heavy durable tape on the inside of switch box to prevent wear of seat side. Note: Position hose clamps to prevent wear on seat and avoid a catch hazard for rear occupant legs. Coil extra wire below back seat. Note: It is best to coil the excess wire before routing to prevent un-needed twisting. Route the Actuator Wire up the back of Mast. Best to be on the back and under Foam protector, then secure with Zip Ties. Attach Power Source to Hot Box on a 5 amp max. circuit. We use the Strobe circuit, to power both the Strobe and Trim. And ground shield to empty negative post. If the Rocker functions backwards to your preference, simply switch the 2 power leads to reverse function. Hot Box wiring shown on next page.

22

Hot Box located behind back seat.

Ensure that wires will not interfere or be caught or cut, when folding the Trike for Wing removal and installation. Cycle trim to insure nothing is catching.
