$12.56Graco 190484 Shim is engineered to provide precise tip clearance adjustment within high-pressure airless pump systems. By setting the optimal gap between the pump vane and housing, this shim maintains stable fluid flow, consistent atomization and prevents premature wear on critical pump components. Highly straightforward to integrate, it supports recurring maintenance cycles and guarantees uniform performance across demanding coatings applications. Professionals trust this component for its exact tolerances and reproducible thickness, ensuring each spray session delivers uniform coverage and minimal downtime.
Crafted from high-grade stainless steel with a corrosion-resistant plating that endures solvent and abrasive coatings, this shim delivers mechanical stability under extreme pressures. Precision machining ensures thickness tolerances within ±0.0001 inches, guaranteeing reproducible dimensions across batches. A micro-finish surface treatment reduces insertion friction and prevents galling within the seal plate. Chamfered edges facilitate seamless alignment during service and protect pump housing surfaces. Each shim’s hardness rating is optimized to withstand repetitive compression cycles without deformation, reinforcing reliability in demanding airless coating environments.
Inserting the shim into the pump assembly requires minimal disassembly and only basic hand tools, typically a hex key and a calibrated torque wrench. Begin by depressurizing the system and removing the manifold cover plate. Slide the shim between the seal plate and vane retainer, ensuring edges align flush with mating surfaces. Applying the manufacturer-recommended torque of approximately 80 in-lb to the manifold bolts prevents leaks without warping. After reassembly, perform a low-pressure test and recheck torque after the first operating hour. Precise adherence to these steps preserves clearance and integrity.
Thickness options for the Graco 190484 Shim range from 0.005 to 0.020 inches, accommodating a variety of fluid viscosities and pump designs. Rockwell hardness typically measures between C48 and C52, balancing durability and elasticity. With a nominal outer diameter of 1.25 inches and negligible weight addition, it integrates seamlessly into standard pump modules. Tolerances within ±0.0001 inches ensure predictable fluid dynamics, while chemical compatibility with common solvents extends service life. Detailed quality control inspections and traceable certification accompany each batch for comprehensive documentation.
Optimized clearance provided by this shim improves atomization efficiency, yielding finer droplet distribution and smoother finishes. Production lines benefit from reduced spray pressure fluctuations and uniform coating thickness across large panels. Incorporating the shim reduces pump cavitation and extends tip lifespan. Operators report quicker start-ups and fewer purge cycles when using a correctly sized shim. Coupling this component with the graco 395 airless paint sprayer maximizes throughput and finish consistency.
Although originally designed for a range of Graco HY and Xtreme series pumps, this shim integrates seamlessly with many 201-series and 5900-series fluid ends. Versatility allows retrofit into both direct-mount pumps and cart-based sprayers. OEM guidelines confirm compatibility when installing alongside a graco 490 paint sprayer, ensuring that recommended gap settings fall within manufacturer specifications. Industrial painters appreciate how easily it adapts to diverse equipment platforms without compromising performance.
Regular inspection of the shim during routine service intervals reveals surface wear or micro-cracks early. Cleaning with solvent-compatible solutions and gentle brushing removes coating residues. Replacement frequency depends on material pumped and duty cycles; many professionals schedule shim checks every 500 operating hours. Storing shims in a dry environment prevents corrosion. Keeping a small inventory of spare shims reduces machine downtime. Such proactive maintenance is vital when servicing a graco 695 paint sprayer.
Incorporating a precision shim upgrade transforms maintenance workflows and enhances equipment longevity. Return on investment is realized through lower consumable costs and improved application speed. Fine-tuning clearance delivers a competitive edge in quality control, especially on critical architectural and automotive projects. Value-conscious operators find this upgrade more cost-effective than complex pump redesigns.
By refining tip clearance and ensuring stable fluid flow, the Graco 190484 Shim enhances spray reliability and finish quality. Technicians benefit from straightforward installation and precise engineering backed by detailed specifications.
