Bedford 57-1748 is Graco 183563 Piston Rod aftermarket replacement

Graco 183563 Piston Rod — AfterMarket by Bedford Precision Parts

This direct-fit piston rod is an AfterMarket by Bedford Precision Parts replacement for the Graco 183563 (also referenced in older manuals as 183-563). It’s sold as Bedford P/N 57-1748 and built in the U.S.A. to restore smooth piston travel, fast priming, and steady output on professional rigs.

Where it fits & how it’s used: Designed for Graco Nova (Ultra-style), Fuller OBrien Pro 501, Ultra 400/500, and EM-series pumps (EM380/390/490). Install this rod when you notice pressure loss, slow priming, or irregular spray patterns—the refreshed drive helps stabilize pump performance for consistent finishes across shifts.

• Aftermarket value: Bedford engineering and materials deliver OEM-level fit at a cost-effective price point.
• Drop-in replacement: Matches OEM form/fit/function to minimize downtime during scheduled service.
• Built for uptime: Precision machining supports prime/hold characteristics and uniform film build in demanding duty cycles.

Installation tips: De-pressurize and flush the sprayer, then follow your pump manual for disassembly and torque specs. Inspect the cylinder and packings for wear, lubricate on reassembly, verify the system’s pressure relief valve, and perform a low-pressure leak check before returning to full output.

Pro results, end to end: A healthy lower performs best with clean filtration and the right gun-side setup. During the same service window, consider renewing consumables to keep patterns crisp and overspray low.
