{"product_id":"s-s-90-99-b-t-pinion-shaft-gear-conversion-kit-blue","title":"S\u0026S 90-99 B.T - pinion shaft gear\/conversion kit - Blue","description":"\u003cp\u003eBlue color coded for average size. Stock replacement for all L77-89 B.T. models. Used as conversion kit on 90-99 Evo B.T. with pre-90 pinion shaft. For 1989 and earlier type pinion shafts used on 90-99 Evo B.T. models (engines that use S\u0026amp;S flywheels or other multiple parts flywheel assemblies) S\u0026amp;S offers this conversion package. Kits include a color coded 77-89 pinion gear, 54-89 oil pump drive gear, 54-89 pinion shaft gear spacer and a 54-89 pinion shaft gear nut. \r\n\r\nNote see: 531306 Black (smallest), 531308 Blue (average), 904148 Red (average), 531309 Yellow (biggest). \r\nNote: All kits must be used with a 73-99 B.T. style oil pump driven gear (S\u0026amp;S 531209 \/ OEM 26345-73). \r\nNote: If the stock gear is unmarked and the size is unknown or you are scratch building an engine and without gear, S\u0026amp;S recommend a gear in the middle of the size range. These sizes were used more often and should provide adequate gear clearance under most circumstances. When in doubt, use a gear from the middle to the small side of the range, because a combination of looser fitting smaller gears will give a harmless clicking sound but to tight can cause a wining sound, binding and premature wear. Consult the factory service manual for information on optimum cam gear to pinion gear fit instructions before you order.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Pinion conversion kits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 33-4181\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"S\u0026S","offers":[{"title":"Default Title","offer_id":63008386974026,"sku":"MSH-531308","price":1699.0,"currency_code":"DKK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/531308k.jpg?v=1787172131","url":"https:\/\/partsdenmark.dk\/products\/s-s-90-99-b-t-pinion-shaft-gear-conversion-kit-blue","provider":"Parts Denmark","version":"1.0","type":"link"}
