{"product_id":"20882","title":"Multiquip 20882 Gearbox Assembly HDA 13H - OEM Replacement Part","description":"\u003cp\u003eThe gearbox assembly is the core power transfer component in walk-behind trowels, located beneath the engine to transfer rotational power to the rotor while governing trowel blade speed. This precision-engineered unit houses both input and output shafts that work together to deliver controlled rotor speeds ranging from 35 to 225 rpm for optimal concrete finishing performance.\u003c\/p\u003e\n\n\u003cp\u003ePower flows from the engine through a V-belt pulley system and centrifugal clutch to the gearbox input shaft, which then drives the output shaft connected to the blade rotor. The internal worm and worm gear set must be replaced as a matched pair when worn. Common failure symptoms include clutch slipping, sluggish response to engine speed changes, difficulty rotating the input shaft by hand, or complete failure of blade rotation despite engine operation. Troubleshooting includes checking input and output shaft bearings for wear and verifying that the gearbox shaft rotates freely when the input shaft is turned.\u003c\/p\u003e\n\n\u003cp\u003eThis complete gearbox assembly is designed for HDA Series walk-behind trowels featuring Honda GX340 or GX390 gasoline engines. These professional-grade trowels operate at 327 lb. working weight with a 46-inch path width and 48-inch ring diameter.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with the following models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHDA-SERIES Walk-Behind Trowels\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Multiquip OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Multiquip","offers":[{"title":"Default Title","offer_id":43066617626672,"sku":"20882","price":3358.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/20882.png?v=1779816000","url":"https:\/\/cce-industries.com\/products\/20882","provider":"CCE Industries","version":"1.0","type":"link"}
