The Graco 160623 Arm, Toggle is a precision-engineered linkage component designed to transform rotational motion into linear displacement within air motor drive assemblies and diaphragm pump systems. This critical actuator serves as the mechanical fulcrum that engages pump diaphragms or piston valves, delivering consistent stroke length under operating pressures up to 3000 psi in high-volume coatings applications. Manufactured to OEM tolerances, it provides repeatable actuation cycles without lateral play, minimizing dynamic stress on seals and bearings. Integration into modular pump manifolds ensures optimized fluid routing and compatibility with a wide range of solvents, resins, and viscosity grades used in heavy-duty industrial painting. Its robust pivot interface is compatible with President Air Motor models and other Graco pump platforms. Designed for straightforward replacement and retrofit, this toggle arm enhances system uptime and aligns with preventive maintenance schedules. Built to support rapid cycling rates exceeding 200 strokes per minute, it underpins the reliable performance of an airless sprayer assembly in demanding production environments.
Graco’s selection of aerospace-grade alloy steel for the 160623 Toggle Arm undergoes a multistage heat-treatment process to achieve a Rockwell hardness in the 45–50 HRC range, balancing toughness and fatigue resistance. Advanced surface finishing techniques, such as phosphate coating or specialized passivation, provide exceptional corrosion resistance when exposed to waterborne and solventborne formulations. Dimensional tolerances are held to ±0.001 inch on critical pivot diameters and shaft bores, ensuring interchangeability without rework. Each arm receives a final inspection on a high-precision coordinate measuring machine (CMM) to verify geometric dimensioning and tolerancing (GD&T) features. Assembly considerations include a polished pin interface to reduce frictional torque and extend the service interval. This attention to material metallurgy and manufacturing consistency supports prolonged seal integrity and reduces the likelihood of equipment downtime during large-scale spray and dispense operations. The result is a component ideally suited for demanding work with professional coatings across automotive, aerospace, and heavy machinery finishing lines.
The toggle arm geometry has been optimized via finite element analysis to distribute stress uniformly along the bending axis and avoid local stress concentrations under high thrust loads. Critical dimensions such as lever arm length, pivot offset, and angular range are specified to maximize volumetric throughput while preserving seal longevity. The design accommodates high-pressure filtration systems upstream, protecting against particulate ingress that could accelerate wear in the pump chamber. Key performance metrics include a dynamic fatigue life exceeding 50 million cycles at 2500 psi operating pressure and allowable angular deflection within 0.5 degrees to maintain alignment under thermal expansion. Special attention is given to joint clearance and lubrication paths to minimize stiction and start-up force requirements. Integration points are compatible with standard 5/16" pivot pins, and the toggling motion produces minimal lateral load on bearings. Extensive bench testing validates the component’s performance against cycle rate, load amplitude, and temperature extremes to ensure reliability in harsh manufacturing environments.
In field deployment, the 160623 Toggle Arm demonstrates superior pump efficiency by maintaining consistent stroke volumes and reducing pulsation in the fluid stream. Operators report improved finish quality and reduced overspray when paired with correctly tuned system pressures and nozzle selections. Preventive maintenance procedures recommend inspecting the arm for surface scoring, ensuring pivot-pin lubrication using manufacturer-approved grease, and verifying tightness of retention fasteners every 500 operational hours. Its robust architecture contributes directly to minimizing downtime, as the component can be swapped without disassembling the entire manifold block. Performance validation includes checking actuation force with a calibrated load cell and confirming actuation frequency using optical sensors. This component’s reliability supports continuous production runs, translating into lower total cost of ownership and simplified service logistics. Enhanced high-pressure filtration, combined with optimized arm dynamics, ensures long-term stability in fluid delivery systems while maximizing pump efficiency and extending overall seal longevity under demanding industrial conditions.
