![]() The phillips head screws are a point size number 2, and the best screwdriver bit is an APEX 480-2-ACR2. The APEX 480-2-ACR2 has an anti-camout tip. This bit has ridges which grip the screw slot to help keep the head engaged with the screwdriver bit. Check the bits you purchase to make sure they have the ridges on all faces or on the face used to remove screws. I mounted the screwdriver bit in a 3/8" drive adaptor, so that it could be driven with POWER TOOLS! The hex bolts are a 5/16" and/or 3/8" socket size. Some linkage bolts are press fit, and require the use of a simple c-clamp type press to remove them without damaging the threads. You will need extensions (1/4" drive for some locations), swivel adaptors. Wiss Metalmaster Compound action snips M3R with the yellow handles, can be used to cut wiring or cable clamps and they are easy on your hands! The throttle quadrant has two pulleys mounted on the rear. They need to clear the rudder cross tube. If you position the captain's rudder pedals "Forward," using the hand crank, and the First Officers' rudder pedals full "Aft," using the F/O hand crank, this will position the cross tube in the most aft position. Since I will not be using any of the existing wiring in the aft electronics console, I used the snips to cut the wiring flush with the bottom of the throttle quadrant. There is a cable clamp directly below where the wires exit the throttle quadrant, once this clamp is opened the wires may be pulled from the throttle quadrant. Lift the front of the throttle quadrant and move it forward, so that the rear two pulleys clear the opening, then UP and it's out! Some tips from James Price 737simguy use a small (Flight deck door opening is only 21") shop vacuum to clean up the flight deck, all the screws and washers will be on the bottom, and use a camera to document what you have done, or about to do! I may have missed something, so let me know your suggestions! They are always welcome! | |||||
