Before I could get out of the door to lend a hand, the car''s owner emerged from the steam cloud and sprinted aor for the office. Breathless tool 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 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 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.

Keith/U.S. Tsubaki: The overall costs of a locking device must be balanced against the requirements of the application. Keyless locking devices co handle both high torque and thrust, while increasing shaft aor strength. They are not affected by torsional load reversal or impact, which can damage keys and keyway connections.Jeff/Tollok: tool and One commonly mentioned advantage of keyless connections is that no secondary processes are necessary. The mechanical interference fit principle of a keyless locking assembly precludes having to cut keyways, tapers, splines, or threads. A straight cut hub with a good surface finish by a machine tool is sufficient. Assembly and disassembly is easy and quick, and angular adjustments can be carried out on the spot. And because the connections are backlash free, you don''t need to compensate for mechanical inefficiencies elsewhere in your co machine or controls system. It was a quiet Tuesday morning, about IS minutes before opening the shop doors. All the techs were busy performing their morning rituals -- drinking coffee, reading trade publications and oiling their air tools. Without warning, our otherwise tranquil morning was interrupted by a horrendous screech of brakes as a late-model, metallic-blue BMW M3 slid into the aor service drive. Steam was billowing out from underneath the engine compartment. The driver, a moderately dressed, thirty-something tool suburbanite, jumped out and opened the hood. Instantly, a huge white cloud engulfed him and the entire front half of the car. I fully expected that when the fog cleared, at least one of them would have vanished -- like a magician''s disappearing act.
