It measures 39mm across and has a reverse thread, so it is tightened and loosened in the opposite direction from a standard nut: it turns clockwise to come off. Because of this, it needs careful handling. You will need a starter clutch nut tool to install and remove it properly.

The reverse thread keeps it seated tight during engine operation so it does not work loose on its own. Use the correct tool when servicing it, since the wrong one can damage the nut or nearby engine parts.\u003c\/p\u003e\u003ch3\u003eWhen to Replace\u003c\/h3\u003e\u003cp\u003eThink about replacing the starter clutch nut if you see wear or damage such as stripped threads or cracks. A worn nut may not engage the starter clutch properly, and that can hurt engine performance. Checking it regularly helps you spot problems early and keeps your engine running reliably.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e M22x1.00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter:\u003c\/strong\u003e 30.5mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Reverse Thread\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e GY6 150cc (157QMJ) engines, including 125cc, 150cc and 169cc 157QMJ-based engines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eGY6 150cc (157QMJ)\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eHow to choose:\u003c\/strong\u003e Compare the engine code stamped on your engine against this list: 157QMJ, 161QMK, 152QMI, 1P61QMK, YN1P57QMJ, 1P52FMI, 154FMI, JJ157QMJ, 1P57QMJ, BN157QMJ or BN161QMK-A.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it goes:\u003c\/strong\u003e Refer to part #6 on the starter diagram for the GY6 150cc (157QMJ).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eShop more:\u003c\/strong\u003e \u003ca href=\"\/collections\/gy6-scooter-parts\"\u003eGY6 Scooter Parts\u003c\/a\u003e · \u003ca href=\"\/collections\/chinese-scooter-parts\"\u003eChinese Scooter Parts\u003c\/a\u003e · \u003ca href=\"\/collections\/scooter-clutches\"\u003eScooter Clutches \u0026amp; Clutch Springs\u003c\/a\u003e · \u003ca href=\"\/collections\/scooter-starters-relays\"\u003eScooter Starters \u0026amp; Relays\u003c\/a\u003e · \u003ca href=\"\/collections\/scooter-parts\"\u003eScooter Parts\u003c\/a\u003e\u003c\/p\u003e","brand":"Trend Times Toy Stores","offers":[{"title":"Default Title","offer_id":51138797568057,"sku":"TT-26797","price":1.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0665\/3358\/9049\/files\/starter-clutch-nut-notched-reverse-thread-39mm-for-gy6-1.jpg?v=1794377863","url":"https:\/\/www.trendtimes.com\/products\/gy6-starter-clutch-nut-notched-reverse-thread-39mm","provider":"Trend Times Toy Stores","version":"1.0","type":"link"}
