Install The Wheel Pants - GREAT PLANES RV-4 Instruction Manual

4. Position the cowling so that there is approximately
3/32" [2.4mm] between the back of the spinner plate and the
front of the cowl.
5. Mark the position for the cowl on the fuselage. Drill three
1/16" mounting holes in the cowl and into the fuselage. One hole
should be located in the top of the cowl. The other two should
be drilled on the side at the bottom of the fuselage. Remove the
cowl and drill a 3/32" [2.4mm] clearance hole through the three
mounting holes your drilled in the cowl. Do not drill clearance
holes in the fuselage. Apply a drop of thin CA into each of the
mounting holes in the fuselage.This will harden the wood, giving
a stronger surface for the screws. Mount the cowling to the
fuselage with three #2 x 5/8" [15.9mm] sheet metal screws.
6. Cut holes in the cowling to provide access to the
muffler, glow plug and the needle valve for the engine you
have installed.
