637316 ARO Air Motor Section Service and Repair Kit
P/N 637316 ARO Air Motor Section Service and Repair Kit
The ARO 637316 Air Motor Section Service and Repair Kit is a replacement service kit designed for the air motor section of compatible ARO 3" industrial piston pumps, including model series NM2304A and NM2304B 4:1 ratio two-ball pumps utilizing the 66913 air motor. This kit includes replacement U-cup packings, gaskets, O-rings, and specialized lubricant required to overhaul and maintain the pump's air motor section. Designed to handle maximum air pressure, this kit helps restore proper pneumatic sealing and smooth cycling. For a successful installation, housing bolts should be properly torqued during reassembly.
Please verify your pump and motor model before ordering to ensure compatibility, as this is an air motor section service and repair kit only and is not a complete air motor assembly or complete pump.
