Series A is designed to serve as a direct replacement for the Marley right-angle drives. The drives are built with the same critical mounting dimensions to simplify gear-drive replacements. The gear housing foot patterns are identical, eliminating the need for tower-gear-drive-support modifications. Also, the input shaft diameters and keyways match the Marley design, so couplings and drive shafts do not have to be replaced. According to the company, reduction ratios are within ±2 percent of the Marley units, eliminating the need to make fan pitch adjustments.
