{"product_id":"bartell-10104-under-engine-spacer-5-16-oem-replacement-part","title":"Bartell 10104 Under Engine Spacer 5\/16 - OEM Replacement Part","description":"\u003cp\u003eThis 5\/16\" spacer fits directly beneath the engine on Bartell walk behind power trowels, maintaining the correct vertical alignment and load distribution between the engine mounting surface and the machine frame. When this spacer is worn, missing, or damaged, the engine can sit unevenly, placing stress on mounting hardware, misaligning drive components, and accelerating wear on belts and blade assemblies. Replacing it promptly restores proper engine positioning and protects the drivetrain.\u003c\/p\u003e\u003cp\u003eThe B446 and B446 Mega-T are heavy-duty commercial trowels running Honda GX270, GX340, or GX390 engines producing up to 11.7hp (8.7kW), with blade speeds of 180 RPM and operating weights of 240-260lbs (109-118kg). At these power and load levels, precise engine mounting geometry is critical. A correctly seated under-engine spacer ensures even clamping force across all mounting points and helps prevent vibration-induced fastener loosening during operation. When inspecting or reinstalling the engine, whether during routine service, belt replacement, or engine swap, this spacer should be inspected and replaced if any deformation or compression set is evident.\u003c\/p\u003e\u003cp\u003eCompatible models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBartell B446\u003c\/li\u003e\n\u003cli\u003eBartell B446 Mega-T\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGenuine Bartell Global OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Bartell","offers":[{"title":"Default Title","offer_id":43412748271664,"sku":"10104","price":36.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/10104.jpg?v=1784312807","url":"https:\/\/cce-industries.com\/products\/bartell-10104-under-engine-spacer-5-16-oem-replacement-part","provider":"CCE Industries","version":"1.0","type":"link"}
