Genuine Echo Speed-Feed 450 Bump Cap X472000031 | SRM-266 SRM-280 SRM-3020 OEM
Is your trimmer head refusing to "bump" out new line, or has the bottom cap worn through to the spring? The bump cap is the sacrificial hero of your trimmer. This Genuine OEM Echo Lid Drum Cover (X472000031) is the factory-original replacement specifically for the heavy-duty Speed-Feed® 450 head.
Don't be fooled by "universal" caps that don't click into place or use soft plastics that wear out in a single afternoon. This Authentic Echo/Shindaiwa part is made from high-density, abrasion-resistant polymer designed to take thousands of bumps against grass, dirt, and gravel while maintaining a secure lock on your trimmer line spool.
Engineered Wear Surface: Thick-walled construction at the contact point provides a long service life and consistent "bump" sensitivity.
Precision Locking Tabs: Features the exact tension required to stay locked during 10,000+ RPM operation while remaining easy to remove for cleaning.
Smooth Glide Profile: Designed to minimize turf gouging, allowing the trimmer head to float over the grass for a professional finished look.
Perfect Internal Clearance: Maintains the exact gap required for the Speed-Feed® spring to compress, ensuring you never "over-feed" or jam your line.
Direct Factory Fit: Specifically for the 450 head (the larger commercial version), ensuring a dust-tight seal for the internal gears.

🛠️ Trimmer Pro-Tip: The bump cap is your "wear gauge." Diagnostic Tip: If the center of the cap feels "spongy" or you can see the metal spring through the plastic, replace it immediately. A worn cap causes the line to advance uncontrollably. Maintenance Tip: When you replace the cap, take 30 seconds to clean the grass "syrup" and grit out of the internal housing. Installation Tip: To install the X472000031, line up the arrows on the cap with the eyelets on the head and push until you hear a solid "click" on both sides. Pro-Check: Give the cap a firm tug before starting the engine; if it isn't fully seated, it will launch off the shaft at high speed!
