The case set is supplied without serial numbers, and a Bill of Sale will be issued for the blank cases. The rear motor mount halves are stamped with the numeral “7” to denote 74 cubic inches; builders may also stamp these numbers in.\u003c\/p\u003e\n\u003cp\u003eOil from the top end returns through the pushrod tubes rather than through the cylinder base. The case accepts loose roller bearings on the sprocket and pinion shaft sides and includes pinion and sprocket shaft races. When mounting the oil pump body, use two gaskets for proper clearance.\u003c\/p\u003e\n\u003cp\u003eBefore final assembly, confirm the main bearing fitment clearance using the supplied technical guidance. Multiply the standard bearing measurement by two, then add that result to the left-side sprocket shaft measurement. For example, a .250-inch standard bearing measurement multiplied by two equals .500 inch; adding a 1.000-inch left-side sprocket shaft measurement produces 1.500 inches, indicating 1.501-inch fitment with .001-inch clearance. This set is sold as a complete case set and is manufactured in Taiwan.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eApplication: Designed as a replacement for original cases on 1941–1947 Harley-Davidson FL models\u003c\/li\u003e\n\u003cli\u003eCase Design: Oil from the top end returns through the pushrod tubes rather than through the cylinder base\u003c\/li\u003e\n\u003cli\u003eBearing Support: Accepts loose roller bearings on the sprocket and pinion shaft sides\u003c\/li\u003e\n\u003cli\u003eIncluded Case Components: Includes pinion and sprocket shaft races\u003c\/li\u003e\n\u003cli\u003eOil Pump Installation: Use two gaskets when mounting the oil pump body for proper clearance\u003c\/li\u003e\n\u003cli\u003eIdentification: No serial numbers are provided; a Bill of Sale is issued for blank cases\u003c\/li\u003e\n\u003cli\u003eEngine Marking: Rear motor mount halves are stamped with the numeral “7” to denote 74 cubic inches\u003c\/li\u003e\n\u003cli\u003eUnit of Measure: Set\u003c\/li\u003e\n\u003cli\u003eCountry of Origin: Taiwan\u003c\/li\u003e\n\u003cli\u003eFitment Guidance: Verify main bearing fitment clearance using the stated bearing and left-side sprocket shaft measurement procedure\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\nFitment\u003cbr\u003e\nHarley Davidson FL  1941\u003cbr\u003e\nHarley Davidson FL  1942\u003cbr\u003e\nHarley Davidson FL  1943\u003cbr\u003e\nHarley Davidson FL  1944\u003cbr\u003e\nHarley Davidson FL  1945\u003cbr\u003e\nHarley Davidson FL  1946\u003cbr\u003e\nHarley Davidson FL  1947","brand":"Motorshop","offers":[{"title":"Default Title","offer_id":68143064449209,"sku":"10-0980","price":1539.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/2285\/8794\/files\/10-0980a.jpg?v=1793745202","url":"https:\/\/atticusgoods.com\/products\/motorshop-knucklehead-engine-case-set-for-1941-1947-harley-davidson-fl","provider":"Atticus Goods","version":"1.0","type":"link"}
