Restore Structural Rigidity & Stop Hazardous Fuel Leaks: Genuine Echo Rear Handle Tank

Eliminate cracked handle frames, broken trigger guards, leaking fuel tank seams, stripped anti-vibration mount bosses, and hazardous fuel seepage on your chainsaw. This Genuine Echo Factory OEM Rear Handle & Fuel Tank Assembly (Part Number C041000588) is the authentic structural handle and reservoir replacement engineered explicitly for the Echo CS-490 50.2cc professional gas chainsaw . Operating a high-RPM chainsaw with a fractured handle or leaking fuel cell puts operator safety at severe risk and compromises positive control during bucking cuts.

Manufactured in Japan to Yamabiko’s rigorous commercial forestry standards, the C041000588 is molded from heavy-duty, impact-modified fluorinated polymer engineered to resist blunt force impacts, cold-temperature brittleness, and chemical swelling from ethanol fuels. The precision-engineered assembly integrates the main ergonomic gripping handle, broad lower safety boot-plate (designed to hold the saw firmly down during starting pulls), throttle control channels, and a high-capacity internal fuel cell. Factory-located mounting points mate seamlessly with your engine crankcase anti-vibration spring dampers and AV buffers, keeping hand-arm vibration to factory-minimum levels.

This authentic factory replacement component is cataloged under Echo / Yamabiko OEM Part Number C041000588 (Handle, Rear / Fuel Tank Assembly / CS-490 Gas Tank / Tank, Rear Handle Complete) .

Why This Genuine Echo C041000588 OEM Rear Handle Tank is the Professional Standard:

100% Genuine Factory OEM Component: Manufactured directly by Yamabiko for precise chassis geometry, anti-vibration alignment, and throttle linkage travel.

Heavy-Duty Impact-Modified Polymer: Engineered to survive tough forestry conditions, tree limb strikes, and rough handling without cracking.

Ethanol & Chemical Resistant: Blow-molded polymer prevents fuel vapor permeation, seam splitting, and internal degradation from modern pump fuel.

Complete Ergonomic Rear Handle: Features the integrated top grip, throttle trigger housing, and broad lower foot-step pad for safe recoil starting.

Airtight Fuel Containment: Restores leak-free fuel storage and proper atmospheric tank venting, eliminating fire hazards and vapor-lock stalling.

Factory Anti-Vibration Alignment: Precision-located damper bosses restore factory isolation between the engine crankcase and the operator's hands.

🛠️ Pro-Maintenance Tip: Watch the "Throttle Rod Free-Play & AV Buffer Swap Secret!" Throttle Rod Alignment Secret: When transferring your throttle trigger rod and lockout linkage over to the new C041000588 handle housing, verify that the throttle linkage rod moves completely free without rubbing the plastic internal ribbing before reassembling the carburetor cover! With the throttle lockout depressed, squeeze the trigger fully and look down at the carburetor throttle shaft: the butterfly valve must hit its wide-open stop completely, and snap back fully to the idle screw instantly upon release. If the rod catches, you risk a high-idle runaway on startup. AV Buffer Inspection Secret: When the saw is stripped down for this tank swap, inspect each rubber anti-vibration cushion and buffer spring. Rubber buffers that are fuel-soaked, soft, or cracked should be replaced immediately. Mounting a brand-new rigid handle onto tired, floppy AV mounts will overstress the plastic mounting lugs and cause premature fatigue cracking around the fastener holes.
