Restore Full Cutting Torque & Eliminate Gearhead Grinding: Genuine Husqvarna Gear Kit

Eliminate gear slipping under heavy grass load, noisy metallic whining, seized spindle arbors, and stripped splines on your commercial trimmer. This Genuine Husqvarna Factory OEM Bevel Gear Kit (Part Number 584307001) is the authentic complete lower drive gearbox engineered explicitly for Husqvarna, RedMax, and Jonsered commercial straight-shaft trimmers and brushcutters (directly superseding prior part numbers 528840301 and 584928801) . Operating a commercial trimmer with a damaged or worn gearhead bleeds engine power, causes intense hand-arm vibration, and risks total gear seizure in the middle of a commercial mowing shift.

Instead of gambling with weak aftermarket reproduction gearheads made from soft cast pot metal that strip their internal pinion splines upon the first curb strike, installing this authentic factory component ensures true Swedish commercial-grade durability. Precision-manufactured by Husqvarna from heavy-duty cast aluminum alloy with hardened spiral bevel gears and high-load sealed ball bearings, this complete gearbox delivers optimal gear mesh tolerances and low operating friction. It features a factory split-collar clamp with dual pinch bolts for a solid lock onto the drive tube, a recessed drive-tube locating hole, an integrated grease service port screw, and a threaded spindle arbor engineered to accept standard commercial tap-and-go bump heads and blade adapters.

This authentic factory replacement assembly is cataloged under Husqvarna OEM Part Number 584307001 (584 30 70-01 / Gearhead / Bevel Gear Complete / Gearcase Assy) and directly supersedes / replaces prior OEM Part Numbers 528840301 (528 84 03-01) and 584928801 (584 92 88-01) . (Note: This listing is for the complete gearhead housing assembly with internal spiral gears, bearings, clamp bolts, and grease service plug as shown).

Why This Genuine Husqvarna 584307001 OEM Bevel Gearhead is the Fleet Standard:

100% Genuine Factory OEM Assembly: Precision-engineered to factory blueprints for seamless alignment on 24mm outer diameter drive tubes and factory inner drive shafts.

Hardened Spiral Bevel Gearing: Heat-treated alloy steel ring-and-pinion gear set handles violent blade impacts against rocks and roots without chipping or stripping.

Dual-Bolt Clamp & Locating Pin Boss: Clamps securely to the lower drive shaft housing, preventing the gearbox from twisting out of square during high-speed sweeping.

Serviceable Grease Purge Port: Threaded service port allows quick periodic repacking with genuine high-pressure bevel gear grease to extend bearing life.

Direct Multi-Part Supersession: Fully updates and replaces older part numbers 528840301 and 584928801 across all compatible commercial trimmer fleets.
