Requires a 73-77 breather gear. Only this 36-69 style pump offers an adjustable primary chain oiling system; but is not equipped with a rear chain oiling provision. Offers several options for oil line placement. All S\u0026amp;S billet pumps come complete with everything you need to replace the stock pump and include mounting instructions. Machined with an oil pressure relief bleed off passageway \u0026amp; relieves pressure build up on top of the valve to maintain consistent oil pressure. Oil pressure regulation bypass routes excess oil directly to the supply side of the pump \u0026amp; reduces the amount of oil returned to the tank; reducing foaming and cavitation. Note: Requires 73-77 breather gear. Note: 36-69 engines used with S\u0026amp;S pinion shaft and drive shaft gears will speed-up oil pump by 25%; identical to 73-up models. S\u0026amp;S pumps for 1936–’67 engines used with the S\u0026amp;S oil pump drive gears deliver 33% more oil than the original cast iron pumpNote: There may be more differences in Harley-Davidson crankcases than you might think. Plugging or drilling a hole is sometimes necessary. S\u0026amp;S offers a drill jig as MCS 518150. This is a special tool that is mounted on the crankcase and used as a guide to help you drill holes correctly.\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 36-69 Big Twin (NU)\u003c\/p\u003e","brand":"S\u0026S","offers":[{"title":"Default Title","offer_id":54307909370183,"sku":"519922","price":522.21,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/7812\/0519\/files\/519922k.jpg?v=1784484729","url":"https:\/\/www.chopperessentials.com\/products\/s-s-billet-oil-pump-36-69-style","provider":"Chopper Essentials Co.","version":"1.0","type":"link"}
