{"product_id":"alternator-rotor-clutch-shell-sprocket-assembly","title":"Alternator Rotor \/ Clutch Shell \u0026 Sprocket Assembly","description":"\u003cp\u003eOEM style replacement alternator rotor\/clutch shell with primary chain sprocket combo. Incl. ball bearing. Magnets are encapsulated in a stainless steel shell. This will help prevent magnets coming loose; which fequently happens with OEM equipment. OEM replacement reference 36791-84.  Note: Replacement clutch hub ball bearing is separately available as 556626\/36799-84.  TECH TIP: On L84-90 XL Sportster the alternator is installed on the clutch hub. This was poor design. Excessive clearance between clutch hub bearing; mainshaft ball bearing and needle bearing between the two parts of the transmission shaft allows the clutch hub to cock sideways; enough for contact between stator and clutch hub. Grinding stator and\/or clutch hub is sometimes done; but not recommended by MCS; to add clearance which reduces output. Better is installing new bearings. From 1991-on the alternator was moved and the rotor is run on the sprocket shaft. This fixed the problem.\u003c\/p\u003e","brand":"Mcs","offers":[{"title":"Default Title","offer_id":50010595557704,"sku":"936791","price":732.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2711\/4344\/files\/936791.jpg?v=1779038011","url":"https:\/\/holydeath.com\/products\/alternator-rotor-clutch-shell-sprocket-assembly","provider":"Holy Death Motorcycle Co.","version":"1.0","type":"link"}
