C3 is the loosest clearance, CN (Clearance Normal) is the middle and slightly tighter than C3, C2 is the tightest clearance. Unfortunately there is no definitive guide to what was \"correct\" for most of these motorcycles, as a rule C3 is generally the safest option when rebuilding your engine. *Due to their nature we do not accept returns of bearings. If you are unsure which bearing to purchase to suit your application, please reach out prior to purchase.","brand":"Trophy Classic Cycles","offers":[{"title":"Default Title","offer_id":43223794417727,"sku":"70-2879-C3-H","price":65.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0661\/0350\/9055\/files\/70-2879_c3_triumph_hepolite_bearing_01.jpg?v=1778174801","url":"https:\/\/www.trophyclassiccycles.com\/products\/70-2879-c3-h-hepolite-triumph-unit-650-750-crankshaft-main-bearing","provider":"Trophy Classic Cycles","version":"1.0","type":"link"}
