The Bedford 20-3980 is a direct-fit replacement for the NXT 6500 Air Motor rebuild kit, engineered for pneumatic-driven pump systems in high-volume fluid transfer and coating applications. Industrial maintenance crews and pump service specialists rely on this kit to restore full operational capacity to air motors that experience reduced pressure, inconsistent output, or complete failure in the field.

Air motors subjected to continuous duty cycles accumulate internal wear on rotor assemblies, bearing surfaces, and port plates. This rebuild kit provides the precision components necessary to return NXT 6500 units to OEM performance standards without requiring complete motor replacement.

Common reasons for replacement:

• Reduced air pressure output or inability to maintain consistent pump speed during spray or transfer operations
• Audible grinding, chattering, or irregular noise indicating internal bearing degradation or rotor damage
• Air leakage around motor housing seams or port connections reducing operational efficiency
• Motor stalling or failure to start even with adequate air supply pressure

Manufactured to OEM-equivalent dimensions for proper fit and performance. Compatible Graco equipment models are listed in the Compatible Equipment section below, where available.
