P/N 637434 ARO Air Section Service and Repair Kit
The ARO 637434 Air Section Service and Repair Kit is a replacement service kit designed for the air section of compatible ARO industrial pumps, including model series 6662XX and 6663XX 2" and 3" metallic double diaphragm pumps. This kit includes the necessary replacement U-cup packings, retaining rings, O-rings, air motor gaskets, and specialized Lubriplate® FML-2 grease required to completely overhaul and maintain both the pilot valve and major air control valve assemblies within the pump's center body.
Designed to handle maximum air pressure, this kit helps restore proper pneumatic sealing and smooth cycling, while relying on internal grease rather than external air line lubrication for optimal seal protection. For a successful installation, center body and valve components should be properly torqued during reassembly, and care should be taken to avoid over-tightening fasteners.
Please verify your pump model before ordering to ensure compatibility, as this is an air section service and repair kit only and is not a complete air motor assembly or complete pump.
