Shipping Breakdown And Re-Assembly - Wills Wing RamAir 154 Owner's Service Manual

RamAir BREAKDOWN PROCEDURE FOR SHIPPING AND RE-ASSEMBLY
PROCEDURE
The RamAir 154 can be broken down to approximately 13.5 feet by removal of the rear
leading edges.
STOP: DO NOT REMOVE ANY OF THE CLEVIS PINS OR SCREWS IN THE VI-
CINITY OF THE REAR LEADING EDGE STEP DOWN JUNCTION.
1) The front leading edge of the RamAir is 60 mm (2.36") tubing, into which slides the rear
leading edge of 50 mm (1.97") tubing, with an overlap of 6". Because of the great difference
in diameters of the front and rear leading edges, they are not concentric; that is they do not
share a common axial centerline. Instead, the 50 mm and the 60 mm tubes are tangential
(they contact each other) on a line along the forward edge of the leading edge, just below
the horizontal centerline. (See diagram).Inside the 60 mm front leading edge, six inches from
the rear end, is a 58 mm diameter ryton plastic crescent reducer which is secured in place
by a 3/16" clevis pin which passes all the way through the 60 mm front leading edge. (See
diagram). DO NOT REMOVE THIS PIN.
A second crescent in located at the aft end of the 60 mm front leading edge, where the 50
mm rear leading edge exits. This crescent is held in place with a screw. DO NOT REMOVE
THIS SCREW EITHER.
A reinforcing inner sleeve is located
inside the 50 mm rear leading edge, and
is secured in place by a clevis pin. DO
NOT REMOVE THIS PIN EITHER.
The rear leading edge is slotted at it's
forward end, such that the slots engage
around the clevis pin which secures the
forward crescent.
STOP: THE REAR LEADING EDGE
WILL PROPERLY ENGAGE THE
CLEVIS PIN IN ONLY ONE AXIAL
ORIENTATION. IF INSERTED WITH
180 DEGREES ROTATION, IT MAY
SEEM TO BE ENGAGING, DUE TO
THE FLARE AT THE ENDS OF THE
SLOTS. HOWEVER, FORCING THE
TUBE IN IN THIS ORIENTATION
WILL DAMAGE THE TUBE, SPLIT-
TING THE SLOT OPEN.
