Echo Clutch Side Chain Brake Cover P021046210 CS-370 CS-400 Chainsaw OEM

Echo Clutch Side Chain Brake Cover P021046210 CS-370 CS-400 Chainsaw OEM.

Restore Critical Kickback Protection & Rigid Guide Bar Clamping: Genuine Echo Brake Cover

Eliminate crooked bar clamping, oil leakage, melted plastic housings, and sticky or disabled kickback safety brakes on your Echo chainsaw. This Genuine Echo Factory OEM Clutch Side Chain Brake Cover Assembly (Part Number P021046210) is the authentic complete safety brake and sprocket cover engineered explicitly for the Echo CS-370 and CS-400 chainsaws (directly replacing and superseding prior part numbers P021013401, P021013400, and 43300039431) . Running a chainsaw with a heat-distorted or cracked clutch cover ruins cutting accuracy and leaves the operator vulnerable to serious injury during high-velocity bar kickback.

Manufactured in Japan from Echo’s proprietary impact- and heat-resistant engineered composite polymer, this complete assembly arrives with the internal chain brake mechanism fully pre-assembled from the factory. It includes the heavy-gauge spring steel brake band, high-tension trip release spring, metal guide bar reinforcement clamp plates, and the hand guard pivot linkage. Engineered to withstand high crankcase and clutch drum heat cycles without softening or bowing, it secures the guide bar perfectly parallel to the crankcase, ensuring precise oil delivery from the oiler port straight into the bar rails while channeling chips and sawdust cleanly out the rear exhaust port.

This authentic factory replacement assembly is cataloged under Echo OEM Part Number P021046210 (P021013401 / P021013400 / Cover, Sprocket Guard / Chain Brake Assembly Complete / Clutch Cover) .

Why This Genuine Echo P021046210 OEM Chain Brake Cover is the Pro Standard:

100% Genuine Factory OEM Assembly: Precision-molded in Japan to exact Echo factory dimensions for direct alignment over CS-370 and CS-400 bar studs.

Pre-Assembled Internal Brake Mechanism: Arrives complete with factory-installed steel brake band, actuator linkage, and calibrated heavy-duty trip spring.

High-Heat Composite Polymer: Formulated to resist thermal softening and warping caused by clutch friction and radiant muffler heat.

Reinforced Steel Bar Pad Insert: Heavy-duty steel inner plate prevents bar nuts from pulling through or crushing the composite housing under full tightening torque.

Smooth Sawdust Clearance: Internal cavity geometry prevents wet wood chips and resin from packing around the drive sprocket and clutch drum.

🛠️ Pro-Maintenance Tip: Watch the "Brake Reset Position & Bar Nut Torque Secret!" Installation Reset Secret: Before attempting to install this P021046210 cover onto your saw, always verify that the chain brake is in the disengaged / tripped-back position ! If the brake band is tripped forward (engaged), the circular steel band will be constricted and will not fit over the clutch drum. Pull the front hand guard lever firmly back toward the top handle until you hear and feel a loud, distinct mechanical "click," which expands the steel band to drop effortlessly over the drum. Bar Nut Torque Caution: When clamping your bar and chain, tighten the bar nuts hand-tight with your scrench, lift the nose of the guide bar up to set the chain tension, and then snug the nuts down firmly. Avoid using oversized cheater bars or impact tools, which can strip the bar stud threads in the magnesium crankcase.
