Its job is to keep engine oil contained within the crankcase. Part of our \u003ca href=\"\/collections\/gy6-scooter-parts\"\u003eGY6 scooter parts\u003c\/a\u003e range, it helps stop leaks so the engine runs cleanly.\u003c\/p\u003e\u003ch3\u003eConstruction and Design\u003c\/h3\u003e\u003cp\u003eThis seal is made from Nitrile Butadiene Rubber (NBR), a material that holds up well against engine oil, heat, and everyday wear. It has two lips, and the extra outer dust lip keeps road grit out of the seal area, which helps protect the crankshaft. Measurements are 20mm inner diameter, 30mm outer diameter, and 5mm width, so it seats accurately.\u003c\/p\u003e\u003ch3\u003eFunctionality and Maintenance\u003c\/h3\u003e\u003cp\u003eAn internal tension spring keeps steady pressure against the shaft, including when temperatures swing. Check this part regularly and replace it when needed to maintain a good seal and avoid oil leaks, since leaks can cause serious engine damage over time.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Nitrile Butadiene Rubber (NBR)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 20mm ID x 30mm OD x 5mm Width\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition:\u003c\/strong\u003e Crankcase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e GY6 150cc (157QMJ) engines; generic fit for most 125-150cc GY6 air-cooled 4-stroke engines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eGY6 150cc (157QMJ) (crankcase position)\u003c\/li\u003e\n\u003cli\u003eTaoTao Lancer, Icebear Blaze II, Wolf EX-150 (GY6 150cc 157QMJ engine)\u003c\/li\u003e\n\u003cli\u003eZnen \/ Jonway YY150T-8, YY150T-12, Falcon 150, Roar 4 (GY6 150cc engine)\u003c\/li\u003e\n\u003cli\u003eBMS \/ Puma Heritage 150, Romeo, Juliet, La Vie 150 (GY6 150cc engine)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eHow to choose:\u003c\/strong\u003e Select a seal that matches your crankcase dimensions of 20mm ID x 30mm OD x 5mm width.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it goes:\u003c\/strong\u003e Refer to part #12 on the crankcase 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-gaskets-seals\"\u003eScooter Gaskets \u0026amp; Seals\u003c\/a\u003e · \u003ca href=\"\/collections\/scooter-engines\"\u003eScooter Engines \u0026amp; Engine Parts\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":51138802942009,"sku":"TT-26829","price":2.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0665\/3358\/9049\/files\/gy6-crankcase-oil-seal-20-30-5-1.jpg?v=1794377909","url":"https:\/\/www.trendtimes.com\/products\/gy6-crankcase-oil-seal-20-30-5","provider":"Trend Times Toy Stores","version":"1.0","type":"link"}
