It is used at the helm during a wheel swap or when pairing an aftermarket wheel with an existing SeaStar or BayStar mechanical or hydraulic steering system. The adapter is a precision-machined fitting designed to bridge the two shaft geometries so the wheel seats and locks securely without play. Because it is a dedicated hub adapter rather than a universal spacer, it is intended specifically for the 3\/4 inch taper to 1 inch straight conversion, and it ships as a standalone component for installation with the wheel's existing mounting hardware. This part falls under helm pump and steering hardware and is identified by the part number HB0573.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e SeaStar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e HB0573\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Adapter, 3\/4 Inch Taper to 1 Inch Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Helm Pumps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 10 x 9 x 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 731957801432\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the SeaStar HB0573 adapter do?\u003c\/strong\u003e The HB0573 converts a 3\/4 inch taper steering shaft to a 1 inch straight shaft so a steering wheel sized for one shaft profile can be mounted on the other.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shaft sizes does the HB0573 fit?\u003c\/strong\u003e It adapts a 3\/4 inch taper shaft to a 1 inch straight shaft, which is the specific conversion this part is designed for.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the HB0573 adapter weigh?\u003c\/strong\u003e It weighs 0.2 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the package dimensions for the HB0573?\u003c\/strong\u003e The HB0573 ships in a package measuring 10 x 9 x 8 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the HB0573 a genuine SeaStar part?\u003c\/strong\u003e Yes, HB0573 is the SeaStar manufacturer part number for this 3\/4 inch taper to 1 inch straight shaft adapter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat steering systems is this adapter used with?\u003c\/strong\u003e The HB0573 is used in helm pump and steering wheel installations, including SeaStar and BayStar steering setups, where the wheel hub and steering shaft have mismatched shaft profiles.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the HB0573 include mounting hardware?\u003c\/strong\u003e The HB0573 is the adapter component itself; it is installed using the steering wheel's existing mounting hardware.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the SeaStar HB0573 adapter?\u003c\/strong\u003e The UPC for the HB0573 adapter is 731957801432.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the HB0573 be used to install a new steering wheel on an older helm?\u003c\/strong\u003e Yes, when the new wheel's hub is machined for a 1 inch straight shaft and the existing helm shaft is 3\/4 inch taper, the HB0573 bridges that difference.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the HB0573 adapter reversible for other shaft combinations?\u003c\/strong\u003e No, the HB0573 is specifically machined for the 3\/4 inch taper to 1 inch straight conversion, not other shaft size pairings.\u003c\/p\u003e","brand":"SeaStar","offers":[{"title":"Default Title","offer_id":48989348102363,"sku":"TEL-HB0573","price":48.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/tel-hb0573_lg__89173.1558180995.500.750.jpg?v=1785188149","url":"https:\/\/www.goodvibesmarina.com\/products\/seastar-hb0573-wheel-shaft-bushing-adapter-3-4-taper-to-1-straight-for-marine-steering-helms","provider":"Good Vibes Marina","version":"1.0","type":"link"}
