Aftermarket GRACO® 206734 Repair Kit for 7 Inch Bulldog & “Adjust-A-Stroke” Air Motors (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 622155

Comparable OEM Part Number: 206734

Description: Total Finishing’s part # 20-631 is a direct-fit replacement for the Bulldog Air Motor (7″) rebuild kit, an essential service component for maintaining GRACO®’s reliable diaphragm-driven spray equipment in industrial and mobile applications.

Pump service specialists and fluid handling technicians rely on air motor rebuild kits to restore performance when pneumatic drive components show wear or responsiveness issues. This kit contains the internal packings, seals, and wear components needed to return the Bulldog motor to OEM operating specifications without requiring a complete unit replacement.

Common reasons for replacement:

• Air motor loses pressure or fails to maintain consistent spray delivery during production runs
• Diaphragm seals wear out after extended use, causing air bypass and reduced pump output
• Internal packings degrade from exposure to fluid residue or moisture in compressed air lines
• Rebuild becomes more cost-effective than downtime when motor efficiency drops below acceptable thresholds

Manufactured to OEM-equivalent dimensions for proper fit and performance.
