Even in the worst of economic conditions, some manufacturers always seem to ride out the storms better than others. A good example of that might be Magnum Products.The company, which manufactures a range of smaller equipment, much of it for the rental and light construction industry, is adding another 70,000 sq.ft. to its existing 50,000 sq.ft. facility that serves as the headquarters for manufacturing and administration. The Berlin, Wis.-based company is more than doubling its size in order to house its expanding product lines, which include: new mobile generators, light towers, water trailers and power buggies, all sold under the Magnum brand name.

On some systems, a portion of the fuel is used for lubrication and cooling. This fuel bypasses the nozzle tip and returns to the fuel tank.Let''s take a quick look at the individual components that make up the fuel system.* Fuel Tanks -- All fuel tanks have a fuel intake fitting on top of the tank for filling and a drain or outlet fitting on the bottom. One or two additional fuel fittings may be found for returning unburned fuel to the tank.Fuel tanks are not trouble-free components. Metal tanks will eventually rust. The rust, combined with water from condensation, forms a mud inside the tank. Sludge forms in the tank when unburned carbon from injector nozzles is carried back to the tank with overflow fuel and combines with water. Thin flakes of hardened mud or sludge can easily plug the fuel outlet hole. This usually occurs when the tank is severely shaken.

* How important is run-out of the installed component?* What are the tolerance or precision requirements of the specific industry you are in?Keith/U.S. Tsubaki: Proper selection requires more than calculating the required torque. Centering requirements, ease of installation, and the forces the unit applies to the shaft and hub also apply.Jeff/KTR: Precisely determine the hub location required for the desired application. Evaluate the radial and axial position and the amount of space available for the locking device, and then select the type of device needed.Andrew/Whittet-Higgins: Choose the right device, taking into consideration static and dynamic loading, assembly, maintenance, misalignment, price of the full assembly, and availability.Vic/Rimtec: Avoiding keyways improves shaft maintenance. Using keyless clamping locking devices or shrink discs makes it easy to change parts.
