Andrew/Whittet-Higgins: Air One pitfall is not allowing the needed spacing in the assembly housing. If the components are not locked together properly, the machinery can fail prematurely. A second pitfall is assuming that a particular torque measurement for one component is correct for the entire assembly.Jim/Stafford: * Using a set-screw collar on a hardened shaft. The screw does not "set," and holding power is greatly diminished.* Using a set-screw collar on thin-wall tubing, which can permanently distort the tubing.* Specifying too thin a width on a clamp-type collar, leaving it too weak to resist distortion when the clamp-screw is tightened.* Specifying too thin a clamp-slot on threaded shaft collars where the collar must flex more in order to adequately clamp onto the threaded shaft.

Before I could get out of the door to lend a hand, the car''s Needle owner emerged from the steam cloud and sprinted for the office. Breathless and clearly shaken, the driver yelled as he came through the door, "Man, you got to help me! I think my Beemer is on fire. There is so much smoke, I can''t even see the engine." "Calm down." I said. "It''s only steam. You have a coolant leak. Why don''t you have a seat and we''ll let it cool down a little before we take Scaers a look at it."He seemed comforted by the fact that his car wasn''t going to burn to the ground. While the steam cloud was dissipating, I Air got all the necessary information from him and then went out to push the car into the shop for a detailed inspection.There was coolant all over the engine compartment, so at first, it was hard to pinpoint where the leak was coming from. We began filling the radiator and before it was full, water began to leak out of a hole in the upper radiator hose.
