Amarillo Marley - Model A Series -Single Reduction Gear Drive

The Single Reduction “A” Series Gear Drives for cooling towers from Amarillo Gear Company are designed as direct replacements for the Marley® right angle gear boxes. Since there are no differences in the critical mounting dimensions, the “A” Series will make Marley® gear box replacements easy. Gear housing foot patterns are identical, eliminating expensive gear drive mechanical support modifications. The input shaft diameters and keyways are the same, so existing couplings and drive shafts do not have to be replaced. All service ports are also easily accessible. Reduction ratios are within ±2% of the Marley® gear box ratios, eliminating the need to make costly fan pitch adjustments.
