Precision Brass Flywheels
Among the most critical components when repowering your locomotives are quality flywheels. As a general rule of thumb, use the largest flywheel(s) that you can fit into your repowering project. A-LINE flywheels are custom precision machined to our specifications from quality brass stock. Concentricity is held to within one-thousandth of an inch (.001") for smooth, quiet operation. A-LINE flywheels are drilled and reamed to allow a slip fit onto motor shafts for easier positioning during installation or removal. Slip fit flywheels should be set with A-LINE flywheel cement #20010 and are superior to their press fit counter-parts because there is no chance of damaging the motor during mounting. Each flywheel includes Athearn coupling or no coupling if it is a Hex drive flywheel and mounting instructions. Each package contains 2 flywheels.
