Graco 15D576 Crowned Spacer

Graco 15D576 Crowned Spacer — Detailed Description

The Graco 15D576 crowned spacer is a genuine OEM component manufactured to fit select Graco texture spray machines. Its crowned design ensures precise spacing and alignment in assemblies where proper spring compression and plate positioning are critical, delivering consistent performance and reduced wear in demanding spray applications.

Key Features & Benefits

• Crowned profile provides accurate seating and alignment in the machine’s spring or bracket assembly.
• OEM specification ensures proper dimension and material compatibility—promoting long service life.
• Helps maintain consistent plate force and spacing under load, reducing the risk of component fatigue or misalignment.
• Minimizes downtime by providing an exact replacement part rather than requiring custom spacers or fabrication.
• Designed for use in tough service environments—ideal for texture and finish sprayers subjected to high cycle counts and vibration.

Compatibility & Application

The 15D576 crowned spacer is listed in the parts breakdown for Graco RTX models and similar texture sprayers where spring plates and spacers are used in pump or cylinder mount assemblies. The part plays a small but essential role in ensuring that spacing and alignment remain within factory tolerances.

Technical Specifications

Installation & Maintenance

1. Turn off the machine and relieve any pressure or energy stored in the system before starting maintenance.
2. Access the assembly where the current spacer is installed—typically under a spring or between bracket plates.
3. Remove any fasteners or components holding the old spacer, taking note of orientation and stack order.
4. Discard the old spacer and clean the mounting surfaces to remove any debris or corrosion.
5. Install the new 15D576 crowned spacer in the same location and orientation as the original; ensure the crowned surface faces correctly if specified.
6. Reassemble the bracket or spring system, torque fasteners to manufacturer specification, and verify that the spacer seats without rocking or misalignment.
7. After installation, run the machine through a short cycle to ensure there is no abnormal noise, bolt loosening or misalignment; inspect periodically during routine service and replace if wear or deformation is observed.

Why This Part Matters

• Even a small spacer like the 15D576 plays a significant role in maintaining proper mechanical geometry—misalignment can cause uneven wear, loss of efficiency or failure over time.
• Using non‑OEM or incorrect spacers can lead to gaps, improper spring compression, noise, vibration or bracket fatigue.
• Replacement is cost‑effective and simple, and ensures your machine continues to perform reliably at factory specs.
