Description
Overview:
The Cup Spring A16 is a genuine Stihl disc-style spring washer designed for use in selected Stihl walk-behind lawnmowers, including the RM 545.0 VM and RM 545.0 VR. Manufactured from high-strength spring steel, it delivers controlled axial preload to keep mating parts tight under load, helping to prevent loosening, vibration, and premature wear. This compact component supports smooth, reliable operation in key assemblies such as drive and control linkages. Engineered to Stihl tolerances for a precise fit, it is identified by MPN 9486 648 0300. If your mower shows signs of rattle, inconsistent drive engagement, or components that won't hold adjustment, replacing a fatigued cup spring with this genuine part can help restore proper function and extend service life.
Key Features:
- Genuine Stihl part for assured fit and performance
- High-strength spring steel for consistent clamping force and longevity
- Helps maintain tension and alignment in drive and control assemblies
- Resists fatigue from repeated loading and vibration
- Compact disc (cup) profile offers strong preload in a small space
- Supports smooth operation by reducing backlash and loosening over time
- Precisely made to Stihl specifications for the listed models
- Simple like-for-like replacement when servicing related assemblies
Typical Applications:
Used where reliable axial preload is needed in Stihl mower assemblies, such as self-propelled drive systems, control linkages, adjustment pivots, and mounting points that see vibration. Ideal when refurbishing worn components, solving recurring loosening, or completing preventative maintenance on domestic and professional lawnmowers.
