Products Description
FS460 Clutch Drum Assembly | STIHL Brush Cutter Centrifugal Power Transfer Interface
Forged Steel Rotational Coupling Module featuring Hardened Running Surface and Integrated Sprocket Drive for Professional 45cc-Class Clearing Saw Power Transmission.
Brush cutter FS460 Clutch drum
The FS460 clutch drum constitutes a critical rotational power-transfer interface engineered to convert the expanding radial force of centrifugal clutch shoes into the rotary motion driving the cutting head of STIHL FS460 professional brush cutters. Machined from a forged or drawn steel billet with a precision-honed internal running surface, it engages with the clutch shoes at a calibrated RPM threshold, transmitting engine torque through the integrated output sprocket to the trimmer head or metal blade. The central mounting bore houses a needle roller bearing or sintered bushing, ensuring low-friction rotation around the crankshaft during idle disengagement while maintaining absolute concentricity under the extreme centrifugal loads of full-throttle cutting. Purpose-calibrated as a direct OEM-standard replacement, this component restores the factory-spec power-transfer efficiency and smooth clutch engagement essential for professional forestry and heavy-duty landscaping operations.
Technical Profiles & Materials
orged Steel Rotational Chassis High-carbon forged steel drum with induction-hardened inner surface (HRC 50-55). Withstands millions of clutch engagement cycles, avoiding surface grooving, judder and shifting engagement RPM.
Low-Friction Crankshaft Bearing Interface Caged needle bearing or oil-impregnated sintered bushing inside the center bore. Precise clearance enables smooth idle rotation and eliminates radial play, eccentric spin, uneven shoe contact & resonant vibration.
Integrated Output Sprocket Drive Precision spline/hex/key drive on drum output locks tightly to trimmer head arbor. Transmits full engine torque without slippage or backlash, reducing spline wear and rattling during throttle shifts.
Thermally Stable Dimensional Control Controlled grain structure from forging & machining keeps consistent inner diameter and concentricity. Stable dimensional accuracy from sub-zero startup to sustained high-temp full-load cutting work.

Products Application
Clutch-System Wear & Engagement Restoration
Serves as the critical drivetrain replacement component for professional clearing-saw operators addressing the classic clutch-drum failure triad: a glazed, grooved, or heat-discolored internal running surface that causes erratic clutch-shoe engagement and slip under load, an elongated or worn output drive interface that produces the audible knocking of a loose trimmer-head arbor, and a collapsed needle bearing that allows eccentric drum wobble and progressive damage to the crankshaft stub and oil seal. component replacement.
Post-Clutch-Shoe Replacement Drum Renewal
Ideally suited for mandatory drum replacement whenever worn or delaminated clutch shoes are serviced. A freshly machined drum surface is essential for the proper bedding-in of new clutch shoes-installing new shoes against a worn, grooved, or heat-damaged drum surface causes accelerated and uneven shoe wear, delayed engagement RPM, and the rapid recurrence of the clutch-slip symptoms that triggered the initial repair.
Professional Fleet Drivetrain Standardization
An essential power-transmission spare component for municipal vegetation-management departments, utility right-of-way contractors, and professional landscaping companies managing fleets of FS460-class clearing saws. The standardized OEM-spec geometry and complete bearing-and-drum assembly format support rapid, single-session clutch-system service, maximizing the operational availability of frontline brush-clearing equipment during the fire-season.

FAQ
Q: Are you an impartial industrial components dealer or a direct China water pump factors factory?
A:We are a direct, ISO9001-certified engineering water pump components manufacturing facility and precision fluid-control factor manufacture exporter primarily based in China. We function our personal cleanroom injection molding bays, computerized ultrasonic welding arrays, computerized hydraulic stress check stations, and clean-room packaging lines, passing direct-factory wholesale price financial savings straight to your element procurement margins.
Q: Can your manufacturing unit furnish full certification forms for food-contact or consuming water compliance?
A: Yes, absolutely. For food, beverage, or scientific applications, our manufacturing unit makes use of one hundred percent virgin, un-recycled polypropylene resins accompanied by means of fabric traceability certificates. We mechanically furnish B2B purchasers with complete FDA compliance documentation, NSF-grade compound declarations, and RoHS/REACH chemical protection screening sheets to make certain clean clearance thru worldwide customs.
Q: Do you provide customization picks for distinctly corrosive fluids like sturdy acids or ozone?
A: Yes, we are a thoroughly succesful OEM/ODM supplier. For aggressive chemical or ozone environments, we can improve the 12x26.5mm valve configuration in our factory: substituting the general PP housing with top class PVDF (Fluoropolymer) and changing any steel springs with Hastelloy or whole springless gravity-ball architecture, making sure final chemical resistance.
Q: How do we impervious a pattern batch to execute computerized lifecycle and burst-pressure testing?
A: We relatively inspire complete laboratory contrast earlier than logging mass grant agreements. We can ship a pattern lot of 5-10 gadgets of our inventory 12x26.5mm take a look at valves for assessment (setup costs and DHL/FedEx air freight apply). Once the factors pass by your inner lifecycle verification and a formal wholesale quantity manufacturing contract or container run is locked in, the sampling charges are a hundred percent credited returned to your industrial balance.
