Hyceker Clutch Cover Kit for Echo CS-370/CS-400 — Complete Chain Brake, Adjuster & Bar Nuts

Hyceker's CS-370/CS-400 clutch cover kit is a drop-in replacement that restores the chain brake, sprocket guard and chain adjuster functionality for Echo CS370, CS400 and CS-420ES chainsaws.

This clutch-side chain brake and cover assembly is designed to match factory fit and function for Echo-compatible models and select Shindaiwa units. Supplied as a complete repair kit, it includes the clutch cover, chain adjuster components, bar nuts and small engine consumables you commonly replace during mid-life service. Each part aligns with Echo part numbers P021046210, P021017220 and related OEM codes, making it straightforward to swap the worn or damaged cover without modifying the saw.

How does this kit restore my chainsaw's safety and chain control?

Replacing a damaged or missing clutch cover re-establishes the chain brake engagement and sprocket protection that prevent accidental chain movement. The included chain adjuster and bar nuts let you set proper tension, while the cover keeps debris away from the sprocket and clutch components.

• Complete clutch cover that houses the chain brake mechanism
• Chain adjuster kit for precise tensioning
• Two bar nuts compatible with factory guide bar fittings
• Sprocket guard integration to shield the drive sprocket from impacts

Which Echo and Shindaiwa models will this part fit?

The kit is engineered to fit Echo CS-370, CS-400 and CS-420ES saws and also matches the clutch-side arrangement used on some Shindaiwa 402s models. It replaces several OEM reference numbers so you can confirm compatibility before ordering.

• Direct fit for Echo CS370, CS400, CS-420ES
