|---|---|
| Product Overview | OEM Titan split-ring lock washer used to prevent fastener loosening due to vibration on compatible AirCoat, Advantage, Helix, Impact, PowrLiner, PowrTwin, SprayTech, and other spray systems. |
| Function | Installed under the head of a bolt or under a nut to provide spring tension that resists loosening caused by vibration, thermal cycling, or dynamic loads. The split-ring design creates tension that resists rotation, maintaining clamping force on critical fasteners. Manufactured from spring steel with appropriate temper, this replacement washer restores proper locking action. The split design compresses under load, maintaining tension as components settle. Regular inspection during maintenance helps identify washers that have taken a set and lost their spring characteristics. |
| Replacement Indicators | Signs that replacement is needed include a flattened or compressed washer that no longer provides spring tension, corrosion damage that has weakened or compromised the washer, a missing washer lost during disassembly or operation, and a broken or cracked split ring. |
| Service Guidance | Lock washers can lose their spring tension after being compressed. Always install a new washer when servicing to ensure proper locking action. Inspect lock washers for flattening or corrosion during regular maintenance. Replace any that no longer provide spring tension to prevent fastener loosening. This washer is used in engine mounts, pump assemblies, handlebar attachments, cover plates, and numerous other locations. |
| Industrial Applications | Professional painting, line striping, fine finishing, and applications requiring reliable vibration-resistant fastening. |
| Compatible Models | AirCoat 423 GB_D_F, Advantage 700/1100/GPX 220, Helix FR/LP/VR, Impact 740/840/1040/1140, Power coat 630 GB_D_F, 1045, 1064, 1072; PowrDriver1, PowrLiner 4950/6950/6950_1, PowrTwin 4900/6900/8900/12000 Plus, SprayTech Airless Advantage EPX2555, SprayTech CS 55/CS5100/CS10000. |

The 9821503 Lock Washer is a genuine OEM component for compatible Titan, SprayTech, and Wagner spray systems. Split lock washers are critical for preventing fastener loosening in high-vibration environments. A missing or ineffective lock washer may allow fasteners to back out, leading to component misalignment, fluid leaks, or mechanical failure. A flattened, corroded, or missing lock washer can allow fasteners to back out, leading to component loosening and potential damage. Regular inspection during maintenance helps identify washers that have taken a set and lost their spring characteristics. Replacing them during service restores the integrity of bolted connections and ensures safe, reliable operation. This part is not listed as a component for the Commander air-powered airless sprayer.
