{"product_id":"30636","title":"Multiquip 30636 Spider Assembly with Arms - OEM Replacement Part for Walk-Behind Trowels","description":"\u003cp\u003eThe spider assembly with arms is the central rotating component that connects and supports the trowel arms on walk-behind concrete finishing trowels. Each arm attaches to the spider plate using a Zerk grease fitting (hex head bolt) and roll pin, allowing the trowel blades to rotate and finish concrete surfaces smoothly. This assembly is critical for maintaining consistent blade pitch and preventing machine wobble or bouncing during operation.\u003c\/p\u003e\n\n\u003cp\u003eThis complete assembly includes the spider plate with integrated trowel arms featuring both hexagonal and round shaft sections. The hex shaft section interfaces with the blade attachment system, while the round section connects to the spider plate through bushings. Each arm includes mounting slots, roll pin holes, and blade attachment bolt holes. Proper maintenance of this assembly is essential—bent or damaged trowel arms can prevent smooth blade rotation and cause uneven concrete finishing. Signs that replacement may be needed include excessive guard ring rocking, uneven blade wear, or a perceptible rolling motion during operation.\u003c\/p\u003e\n\n\u003cp\u003eCompatible with the following Multiquip models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eJ3036H55 Walk-Behind Trowel\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":43067389116464,"sku":"30636","price":700.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/30636.png?v=1779817214","url":"https:\/\/cce-industries.com\/products\/30636","provider":"CCE Industries","version":"1.0","type":"link"}
