The "A" Series right angle gear drives for cooling towers from AMARILLO GEAR are designed as direct replacements for the Marley^® Cooling Tower line of right angle drives. Since there are no differences in the critical mounting dimensions, the "A" Series will make gear drive replacements easy. Gear housing foot patterns are identical, eliminating expensive tower gear drive 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^® reduction ratios, eliminating the need to make costly fan pitch adjustments.
