These high quality gears are carefully machined, heat-treated and then finish ground. If the stock gear is unmarked and the size is unknown we recommend that you order a gear in the middle of the tolerance range. These sizes were used more often and should provide adequate gear clearance under most circumstances. \u003cstrong\u003eNote: \u003c\/strong\u003eGear sizes for 1954 thru 1989 are listed from biggest to smallest. This color coding sequence is identical to stock Harley-Davidson color coding for the late 1977 thru 1989 models. For the 1954 thru early 1977 models there was only one size available from Harley-Davidson, Jims and S\u0026amp;S issued their own color coding for these pinion gears. Sizes are given measured over .105\" pins.\u003c\/p\u003e\n\u003cp\u003eS\u0026amp;S Gear, pinion - yellow - BTl77-89\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Cam Accessories\u003c\/li\u003e\u003c\/ul\u003e","brand":"S\u0026S Cycle","offers":[{"title":"Default Title","offer_id":62567352369482,"sku":"734910","price":1376.0,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/standard-rgba_b3f8eecb-c7bd-42b3-a76a-06e8d1e75a12.png?v=1782770924","url":"https:\/\/partsdenmark.se\/products\/s-s-cycle-pinion-gears-for-big-twin-engine-4","provider":"Parts Denmark","version":"1.0","type":"link"}
